OK, thanks.

But what's the answer to Qs 2 and 3?

Are there any special problems, or steps to be taken, in order to bridge two wireless interfaces on the same device? Can it even be done?

tombrdfrd66

OK. Specific question/s: For a while we're going to have a QRT at one end of the link and the old 'single-chain' wireless and (vertical polarity) antenna at the other end. Do we need to turn one chain off on the QRT or will having the 'other', ie horizontal, chain on still add some dB to the signal?...

tombrdfrd66

If I may hijack this thread, as the original poster appears satisfied, can I as a beginner ask about routing on a bridge? I understand that a bridge essentially just accepts a packet on one interface and spits it out the other so that routing decisions shouldn't be necessary, and that indeed the int...

tombrdfrd66

OK. Thanks.

I've spent a chunk of the community's cash on some QRTs which should arrive tomorrow. Hopefully I'll be able to get them to work.

So does the system itself work out which chain is MIMing and which is MOMing?

tombrdfrd66

4. there is one channel for both polarities. We can answer specific questions such as these. We usually don't have time to write a curriculum of study to take someone from zero to knowledgeable practitioner. Search engines, with the right query terms, are more time effective. I apologize if that se...

tombrdfrd66

Thanks Lambert, but this is a beginner basics board. Your response is the kin to pointing me at a manual of advanced brain surgery because I complained of a headache. Do I take it from what I've read that: 1. Dual chain means the same as MIMO? 2. MIMO involves two antennas at each end of the link? 3...

tombrdfrd66

Beginner Basics? OK, could someone explain what 'dual chaining' is, why you'd do it and how it's implemented on RouterOS and something like the QRT5.

Thx.

tombrdfrd66

Thanks for that.

Are you saying it's better not to disable CSMA?

tombrdfrd66

So here we are, six years after this was first raised - by this poster and a similar set of questions from Wireless Rudy at about the same time - and nstream framing policy is still an arcane mystery. Just the blandest, briefest and most unhelpful skim over the subject in the Wiki, two desperate and...

tombrdfrd66

Thanks InoX. This is new to me. So you have one antenna connected to each of the two MMCX sockets on the board/card? How do you actually get the board/card to drive them? Is it just a case of putting a tick in the "chain 1" boxes in the HT tab in the wireless interface in Winbox - for Tx a...

I've a mountain-top AP serving a few clients in two valleys to north and south. An omni would 'beam' most of its signal over the top of the clients nearest the AP, clearly in sight but hundreds of metres below it.

I want to install an IP camera at a remote site where we have had a few problems, but I also need the ability to turn it on and off to preserve battery power if necessary.

tombrdfrd66

Three-plus years after first posting to this thread I have the problem again - on an RB532A running RouterOS v5.8 I can say the problem is nothing to do with Windows as I can Winbox through this router to Mikrotiks on the subnet behind it. I can ping the wireless interface and Telnet to it but any a...

tombrdfrd66

OK, the links will be 5GHz and there's plenty of room locally, so frequencies won't be a problem. Here's a schematic. Relays B and C are on the same pole connected by ethernet but each can also talk to A wirelessly. Is it better to have each network 192.168.x.x connected to the gateway 10.0.1.1 with...

tombrdfrd66

A pretty basic question, but one hard to define for a Google. I have two wireless network sub-nets each connecting to its own interface at a site which then connects wirelessly over a 15km backhaul to our gateway. As it's a pretty inaccessible mountain-top site I'm considering adding a second interf...

tombrdfrd66

As our local regulators are making noises about enforcing the EIRP regulations I need to ensure that the little non-profit community-run wireless network I do the tech for is within the rules. Could someone take pity and explain the mystery of Tx power to me in words of one sound. I understand the b...

tombrdfrd66

Thanks Patrick.

I'd already pondered a DC-DC converter but was put off by the warning of the heat they produce - using expensive solar power to heat the atmosphere seems counter-productive.

tombrdfrd66

In many examples I have seen in the forums it is advisable to use 24V (2 batteries in series) as over-voltage protection will turn power off at ~28V Forgive me janisk but is this really what we want? I've already had my entire network brought down when a gateway router on top of a mountain turned i...

tombrdfrd66

just be careful, as over-voltage protection will kick in at ~28V (28V is guaranteed to work)

Will the board reboot when voltage drops below 28V again or will it stay off until it's physically disconnected and re-powered?

Also, the less clients on a single radio channel is better to have anyway. I guess this is the crux of it - If you had two clients would you be better giving each its own channel or would an omni manage both perfectly well saving hardware costs, power and channels? Is it the same for twenty clients...

tombrdfrd66

but I don't know the answer. I've a point-to-point backhaul that can handle 10MBps each way, A (gateway) <> B (serving clients).

You have some reading to do. Yeah, I've done some reading. This kind of stuff: "Figure 3 depicts MRC operation graphically for a 1x2 channel. In this example, the two channel gains have magnitudes of 3 and 2. With expected noise power 1, these gains correspond to SNRs of 9 and 4, given that a ...

Isn't it wonderful that a great new protocol like N is developed by a small group of experts, put into effect by a slightly larger group of experts who have the time and know-how to comprehend the technical papers and leaves the rest of us admiring it from a distance and wondering how it's done?

tombrdfrd66

Have been trying to comprehend N. I believe a 1 x 2 antenna arrangement is possible, ie 1 TX/Rx antenna at one end of a link and 2 antennas/chains at the other. If I'm right, at the two-antenna/chain end is it better to have both antennas TX and RX or one TX and one Rx. And in the former case does t...

I want to contol client access to a wireless AP simply by MAC authentication.

Did you try to measure voltage on the batteries and at the end of the cable?

Nothing! No such things are locked.

So if you can't use Nstreeme, clarify the problem in detail instead of b...

Its in the bridge. Did you bridge both ports on B together? Give the IP on B to the Bridge interface.

Or do I need to change the mode of B's wireless to C from "station" to "bridge" to enable it to form a bridge with B's (ap-bridge) wireless to A? Sounds counter-intuitive to me, but then much of MT's config labelling is. (ie 'access' list and 'connect' list. I have to look up to ...

This is a very old product, I don't think we had any distributors in your region when it was sold. So you probably bought the US market version from somebody.

tombrdfrd66

Perhaps whatever damaged the green lines (lightning, surge, etc) also damaged the RB433 port itself (and/or the PC port).

You need to test the RB port and the PC port with a known-working device temporarily.

Yes, that's possible. I'll give it a try. Thanks.

Here I can't find any:
http://wiki.mikrotik.com/wiki/Manual:Interface/L2TP

Here, in black and white:

tombrdfrd66

OK, I give up. According to the manual for v3.0 L2TP-server has a keepalive-timeout setting, but in V3.30 I can't find it. PPTP server set-up has a windows to set Keepalive, but L2TP doesn't. You can set idle-timeout in ppp profile, but not keepalive. Can anyone give me a clue as to the obscure and ...

tombrdfrd66

Thanks tgrand.

I believe I'm beginning to see some trees in the wood, so I'll quit while I'm ahead.

tombrdfrd66

Thank you.

When I get to grips with WDS and discover what L3 is I'm sure I'll be a long way towards mastering bridging.

tombrdfrd66

Thank you. So I have a choice of: A. Using WPA2 security profiles to both protect the routers from unauthorised access and encypt all traffic across the network to prevent it being intercepted and read, or B. Try to secure the routers with Access Lists and only encrypt user's traffic with end-to-end...

I don't think it's a bug - at least in my case - but it is a problem. I initially used PPPoE from MT CPEs to MT AP running User-Manager, but found I was being plagued by duplicate open sessions - UM would report 50-odd active sessions for only a dozen users. So I switched to L2TP and that seemed to ...

This seems so obvious that I must be missing something, tho' I can't find the answer on this board or in the Wiki. How do I stop a remote Dude server?

Thanks. WLAN1 is an AP. WLAN2 could as R<>G is a point-to-point backhaul. So I can bridge two wireless interfaces in AP mode?

Yes, definitely a preference. Might be nice to have it in the tool kit but it's esoteric stuff for those of us who are self-taught. Mikrotik's documentation on the protocols are on a par with their standard 'Brain-surgery for Dummies' approach and on the odd occasion I've experimented with them I'v...

tombrdfrd66

IMHO you have to have way for router to see what route routes where. But only at a 'next step' level. Router B doesn't need to know if the route is via D1 or D2, just that the next step is C1. Just think about it as adding 2 addresses from same subnet to 2 different interfaces - you do not have any...

tombrdfrd66

Well I still don't understand it but you guys must be right because RouterOS won't even let me do it - if I try to add a static n.n.n.n/20 route with a gateway to a dynamic n.n.n.n/20 router with a preferred source it colours it blue and won't do what it's told. Pity. There was a mathematical elegan...

tombrdfrd66

I've learned from this exchange that I can't rely for onward routing on the static routes added to the table simply by reason of the IP addresses given to the interface, and think I understand why. However I still think my network scheme set out above would work simply with one static entry 'reinfor...

tombrdfrd66

IT DOESN'T WORK. Ping works and traceroute works but when the PC at the start of the ethernet link tries to set up a tcp connection it hangs, and from watching the interface traffic it seems to me that replies are reaching the router via the PPP tunnel but then being lost, as through the router does...

tombrdfrd66

It seems to me that the answer is simple, which is what makes me suspicious as anything connected to RouterOS is usually a riddle wrapped in a mystery in an enigma. If I create a PPP tunnel from the CPE to the gateway with the default route via the tunnel as usual, anything internet-bound from the e...

tombrdfrd66

I don't see how either plan would have made the switch between backhauls any different. That would happen at router B? You have routers B1 and B2 both connected to A. Normally the whole network beyond B1 uses the B1<>A backhaul, ditto for B2. However if the link B1<>A fails the B1 network is routed...

tombrdfrd66

Is four routes too much? No, but your example is a fairly simple set-up. I have eight terminal subnets with eight routers nested to three levels, and two back-hauls. I also have a cross link at 'layer B' between two routers to enable internal traffic to avoid the back-hauls and gateway and to enabl...

tombrdfrd66

Take a look at this:
http://www.mikrotik.com/testdocs/ros/2.9/ip/address.php
Select "Proxy-ARP feature" link.

OK, but it looks as though you can only use proxy-arp to 'bridge' one router.

tombrdfrd66

I don't know why you think having many entries in a routing table is bad. The routers handle it just fine. If you want to see fewer, turn on route summarization. It seems bad to me because disentangling a routing table with a dozen entries to work out what's going where and what isn't, really is a ...

tombrdfrd66

The packet never arrives on the router B's interface. If a host is on 172.17.0.0/16 and is told to send a packet to 172.17.17.40 it will ARP for that IP address because it assumes it is reachable on the local broadcast domain. The ARP times out, the packet doesn't get sent. OK (to check my comprehe...

tombrdfrd66

Router B will not just assume that it should relay/forward those packets unless router A tells it to. I was OK up to this point. (Maybe this ought to be in the beginner's basics forum.) I thought the whole justification for a router's existence was to route. It lives to relay/forward packets if it ...

tombrdfrd66

Do you understand now what I meant by "kinda true"? I think I might just be beginning to. With no static routes, router A will have a dynamic entry: ADC...dst=address=10.17.0.0/16...preferred-source=10.17.0.1...distance=0...interface=B so it won't have a gateway as such - in this case 10....

tombrdfrd66

My (erroneous?) thinking was that as the near-by customers were already tunnelling through this router via a route set up to the L2TP server, setting the default route to use an L2TP tunnel starting from this router would only catch traffic generated by the ethernet customer + hotspot users, which ...

tombrdfrd66

You are correct. The routes hinge on subnet length, providing there are no duplicate subnets in the network. Here is a thought. You have three routers connected to router A localnet. Router B with 10.17.16.2/20 Router C with 10.17.16.3/20 Router D with 10.17.16.4/20. According to your routing theor...

tombrdfrd66

Does that make sense? Yes and no. Yes in that I understand it, but no in that it merely confirms that I thought I understood it but... Under my scheme a packet arriving at A addressed to 10.17.17.10 only has one way to go - to B as part of the 10.17.16.0/20 subnet. Once in B it has three 'doors', o...

tombrdfrd66

Ok, I'm a little confused, so let me restate this to make sure I understand the problem. On this repeater unit, you have a backhaul client radio, an AP for near-by customers, a hotspot for laptops, and an ethernet connection to an on-site customer. When your near-by customers start using a PPP conn...

tombrdfrd66

I presume this is a natted net. No masquerade or srcnats in router B. Correct You have duplicate (overlapping) subnets on three interfaces on router B in your original setup. ?You mean that a packet addressed to, say, 10.17.17.10 arriving at B from A has a 'choice' of routes out of A? - ie to the c...
