This NUC is a more PRO-One (XEON) than the 1036 (old with single PSU) running now. 45W TDP makes it a quite energy efficient system. Housing is a bit bigger for thermal reasons.

Larsa

NUCs are really good for home use and this one seems to have a lot of power but may not be the most suitable choice for a "carrier grade" installation. Pick something with at least double PSU and a sufficient cooling system. And needless to say always have a backup unit at hand.

Larsa

With your distance (ie 3.8 miles) to the mast just make sure you have unobstructed line of sight using the higher frequency otherwise it's probably better to stick to B20 with a dedicated external antenna. I would also call both operators to check available LTE bands and where to find the nearest ba...

Larsa

Everything is better than WAP LTE internal antennas. LHG is a lot better on B20 too. Or you can install good external antennas on wap lte. I would not recommend B20 (800 MHz) on either LHG or SXT because of the bad antenna gain at that frequency. Use a dedicated antenna for B20 or even better, take...

Well yes, it should probably have had its own thread. Anyhow, I beg to differ regarding the latency as a local dnsbl call would only lag a few ms which is a very small (even tiny) cost compared to the functional value it would add.

If one care to read carefully, It's actually stated with clear text regarding firehol_level1

"To accomplish this, we include the following IP lists:
. . .
spamhaus drop and edrop - Don't Route Or Peer IPs
. . .
"

Larsa

Yeah, hope they plan to do something about it or create a more manageable/flexible solution in the future. How many lines (give or take) is the end result? I'm wondering since I'm interested to use the Spamhaus drop/edrop "real-time" lists. Will the total aggregate work on a CCR do you th...

Larsa

Absolutely brilliant, altering the block-rules is of course the fastest and most secure way to do it! :idea: Why didn't I think about it myself! :lol: Now I only need to perform some tests to figure out the actual storage limitation on a CCR as I need room for both current and new lists simultaneou...

I was more thinking about the actual routerboards. This is for a LTE-solution with 18 dBi tube mimo antennas. I'm a bit concerned about the 16MB flash on RBM11G and if in any way will force ROS to run in a limited way?

Thanks in advance!

Larsa

Yes indeed!

Rumors say some of the co workers got very puzzled when their personal hotspot stopped working but were still able to use their laptop on the same connection.

Larsa

Well, the regular access is somewhat limited because of previously misuse and someone got the brilliant idea to bypass that limitation. So i'm not quite convinced regarding the business case this time!

Larsa

Well, it's good enough to prevent a "normal" ad hoc installation and not for the professional villain with deeper technical knowledge

Larsa

Excellent, thanks for the pointer! Since it's "flat switched" (like the term btw

it should probably work in this case.

Larsa

Thanks, I'll try TTL to start with!

Any suggestion on a decent value to start filtering on? Btw, is the internal TTL translated/terminated in src-nat and gets another TTL on the outbound side?

Larsa

Is there a any way to prevent people to setting up "personal hotspots" using SMHO WiFi-routers on an enterprise office network? Presume the SOHO-router is assinged a correct ip-address from corporate DHCP-server and is using its own srs-nat, is there a way to detect and block thees kind of...

A reflection regarding the "new" LTE SXT. What purpose does higher speeds have if the downlink still just is 100 Mbit?

Please give us a LTE CAT6 SXT with a MIMO pointing antenna + GbE downlink. Thanks

First of all, please make the transceiver module exchangeable thus do not limit the solution to some specific bands. In that way we can future-proof our customer installations for emerging transmission technologies only by replacing the transceiver module. Think a SXT LTE with a M2 or PCI-SIG compat...

Thanks for the thorough answer and hands-on guidance is always much appreciated as well!

Larsa

dead peer detection should be enabled by default (interval 120 tries 5)

Normally, you set stuff like DPD and Lifetime using the ipsec peer config but what settings are used for the GRE dynamic IPSec tunnels? The GRE Wiki seems pretty brief (or actually completly empty) on this subject ...

Larsa

Don't do it that way! Delete the IPsec Peer and Policy you have now, create a GRE interface, specify source and destination address (the public IPs of the routers) and set an IPsec secret. Then put a /30 network on the GRE interfaces (e.g. 10.0.0.1/30 and 10.0.0.2/30) and route the networks on each...

Larsa

Sorry for the delay- I was a bit more than just busy. So I tested everything again and it is definitely working and I am passing traffic through the tunnel. What I noticed is that the tunnel breaks if one or both of the routers do not have a default route. That was new to me too. -Chris Chris, than...

Larsa

Packet flow diagram will illustrate why you need route for destination even if gateway of that route will not be used: https://wiki.mikrotik.com/images/6/68/IpsecFlow.png So if I understand it correcly, then the only way to set the outbound address of the tunnel is to control pref-src by for exampl...

Larsa

Now you mention it... that makes sense. Thanks.
And I second the proposal for GRE/IPsec
-Chris

I concur, but even if you put GRE/L2PT on top of the tunnel you'll probably get the same issue with the outbound address as before...

Larsa

Sorry, but I forgot to mention that the tunnel gets established but cannot pass any packets since the remote peer gets pref-source from the sending side as the return address i.e outbound address = pref-source. If possible, please enable logging for protocol 50 (ESP) and check for the same behavior....

Larsa

Not back in the office, but I have an idea to check in the mean time: Do you have any masquerade rules configured in /ip firewall nat? I could bet you have. Masquerade always uses the lowest address on the interface, no matter what is defined beforehand. Convert this rule to src-nat (and to-address...

Larsa

Dumb questions -just to be sure: Did you specify that desired address as local-address in the peer definition? Is that address actually really assigned to the router? I have a couple of IPsec tunnels running here with multiple WAN addresses and they're running just fine as expected... -Chris Our tu...

Larsa

You need to set the "prefered source" on the route - it will set the outbound router ip address. Ok, so if I understand you correctly pref-source is the only way you can control the outbound address for a IPsec tunnel. So in case you have a "/29" subnet defined for your WAN, the...

Larsa

Instead of a direct IPsec tunnel, use GRE over IPsec or L2TP over IPsec to establish a tunnel, and route your LAN traffic via that tunnel. That will end all your problems with NAT avoidance etc. Hi! Thanks for the suggestion, but In this case it's not the NAT avoidance that is the main issue, but r...

Larsa

Any suggestion how this can be solved?

Larsa

I recommend you skip the router and hook up a PC directly to the WAN port where you have your mail server. If you are using Windows download nc.exe and then run an outbound test using: C:\> nc -v smtp.gmail.com 25 gmail-smtp-msa.l.google.com [64.233.161.108] 25 (smtp) open 220 smtp.gmail.com ESMTP w...

Larsa

I have picked a number off the 5 of a block and it works fine. Well, thats what we tried. But the outbound ip address always defaults to Pref Source i.e first usable address in the subnet. Since you have to use "accept srcnat Src.Addresse Dst.Adresses" as the first entry to bypass any fur...

Larsa

It quite normal nowadays that operators block outbound smtp port 25 on consumer connections to prevent spam-bots. Test outbound port 25 using Netcat (nc) with verbose and debug flags (usually -D -and -v) from a computer connected directly to the WAN-port. For example use the following command line: ...

Larsa

Is it possible to setup an IPSec tunnel to use a specific public address on a WAN interface that consist of a "/29" subnet (i.e any of the 5 public IP addresses) ? I'm asking since we had some issues with IPsec and the only way to resolve the problem was to pick to the lowest address from ...

Sorry, but a hidden SSID adds no extra security and MAC address can easily be spoofed as pointed out earlier. Use WPA2/AES and choose a password with at least 10 long and mixed characters.

Just curious, why do you want to NAT the internal traffic?

Larsa

Larsa

That's easier then. Use AES over DES. 3DES is notoriously slow in software, and it's unlikely to be optimized in hardware.
