I dont think this is DHCP persay - it only happens with wireless devices - at least the issue I'm observing. Try deleting the wireless client from the registration table either in CapsMan or wireless whichever you are running. Most times this restores the wireless client to working state. It seems t...

Just wanted to ping this as Im still know where on with this. The setup is real simple. SXT-LTE and RB3011 on same /24 subnet. SXT-LTE on .4 and RB3011 on .1. There is EoIP tunnel between the two with the tunnel interface selected as the passthrough interface on the SXT-LTE APN. DHCP client sat on t...

Ferrograph

After upgrading RB3011 from 6.44.3 to 6.45.3, all my PPTP has stopped working, inbound and outbound.

Downgrading one by one PPTP works again only when I got to 6.44.4. Not good!

Ferrograph

I've tried extensively WITH and WITHOUT the SIP helper. You still get zombie connections. Common though is dest-port 5060/5061.

Perhaps there is something in the firewall/NAT that recognises 5060/1 in addition to what the SIP helper does?

Ferrograph

I think we're forgetting that deleting the connections manually or by a script only works some if the time. If the connections get in that wierd state where the timeout starts counting up even deleting them doesn't work - even though they are gone from the connection list I think the that fact they ...

Ive just got RBSXTR. LTE passthrough is broken. I've seen reports that it works on 6.42.7 but I've tried downgrading and it doesn't work.

Well spotted about the /32 addressing.

I just noticed that 6.44beta6 was out and guess what is in the release notes:

lte - fixed DHCP relay packet forwarding when in passthrough mode;

Will test and report back.

Ferrograph

Good point. The beefier Tiks don't need fasttrack. I need to save my pennies and get one!

Ferrograph

PPTP with CHAP is fastest, as per the tile of the post. But a gotcha is that you need to prevent fasttrack from working on VPNs cos it screws them up and you get slow speeds surprisingly. I use the mangle to mark traffic on VPN interfaces in+out with connection-mark "DontFasttrack" (use an interface...

Ferrograph

Ive just got SXT LTE Kit. Standard setup works absolutely great. But the main router (RB3011) needs the LTE WAN address in my setup so Ive tried using passthrough mode and it works to a point but I cant actually get any working internet over the interface. Ive setup SXT on my LAN by using DHCP clien...

Ferrograph

Did you ever get to the bottom of this?

Ive got exact same issue with SXT LTE and RB3011.

RB3011 gets WAN address from LTE via dhcp-client but the connection isnt usable and pings fail with host unreachable.

Ferrograph

Im interested in this method of blocking stuff. Ive been experimenting with using a small list of well chosen names and "catch" words. After doing a bit of browsing on sites well know to be littered with ads and looking through the dns cache, I have good results with this small list. Not perfect by ...

Ferrograph

Ok Partly my bad - I was doing TCP tests and the lower speed is down to TCP overhead. Likely Speedtest.net uses UDP. But the reason I was doing TCP was because I couldnt get UDP test to work - however Ive since discovered that UDP only works if I set the direction to "Both", setting it to "Receive" ...

Ive got a setup (RB941) with roughly 60M/20M wan connection on VDSL (PPPoE). Wired and wireless clients can get upto 58M download speeds from speedtest.net When I test with the built in bandwidth test tool to a btest server than can manage 500M, I only see 20-25M tops. Its pretty standard setup with...

Ferrograph

Actually, I have a theory. I've seen the connections timeout period count upwards which shows they are getting in some weird condition. Maybe the delete doesn't fully delete connections in this state and it gets orphaned and hidden from the list. I theorised that loosing the WAN might do some blanke...

Ferrograph

Still got this issue in 6.41.

I've tried deleting connections but this doesnt always work. In this case the only thing to do is to reboot it. But it gals me to do that - this is about the only thing I have to reboot Mikrotik for. How sad thats its something so basic.

Ferrograph

Set up a default route with the desired gateway (VPN interface or VPN box IP), but add the condition of a routing mark. Say "to_USA"

In the mangle, mark packets with the desired src IPs with the same routing mark. Thats all you need to do.

Ferrograph

If it's pptp, try just CHAP encryption. You might get even more speed.

Ferrograph

Hi all, sorry for trouble, out of sudden I have tried something and fixed it (thinking that the connections that if need to go through "torch" it must be excluded from "fasttrack", which was an idea I read and used on my ipsec to Azure and learnt from somewhere in the internet), the speed now is wh...

CDC_NCM is in our to-do list but I can't comment when we will start to work on that.

Unfortunately I didnt give the post a very good title and forgot to put anything to do with LTE in the title. Oh ...

Ferrograph

Ah, kometchtech! That might be the issue - I had to retire an old GB switch and only had a 100M switch so I moved lower speed devices to the 100M switch and the rest to the remaining GB switch. But its possible and I dont recall the flapping before this. Could be big coincidence of course. I will tr...

Ferrograph

Ok I'll try this next time I go to one of my sites, and report results back.

Ferrograph

Im pretty sure I turned those off (none) but its possible I didnt.

What problem could these potentially cause?

Ferrograph

Ive seen this a few times now and I'd really like to get to the bottom of it. I do a lot of remote monitoring for clients and its very useful to have a Mikrotik on site for diagnosing issues for clients that have their own network. I setup a phone home VPN on the box and just give it either a fixed ...

Ferrograph

Thanks Steve.

Makes me feel a little better about downgrading if I need to. Im trying a few things and monitoring count of link-downs against up time to get a read on frequency of occurrence.

I've been running v6 release candidates for a while now. Currently on v6.41rc38. I'm getting an increasing occurrence of port flapping on ports with cables connected.

Ok Ive spent quite a bit of time on this and reached a conclusion... # Its desirable for our Tik's to get the public IP from a 3G/4G mobile broadband devices - not through HiLink, PPP or other non-ideal method. # A lot of devices now support NCM mode where the public IP is handed over on a special N...

I get this no matter what I try to connect to. Any clues anyone?

Ferrograph

Are the dynamic rules fixed in later versions? Like 6.38.1 I've not seen any release note related to this and things definitely work better with the rules below instead of the default dynamic Tik ones. But really I'd like to just use the default ones. I found these on the forum a long time ago and b...

The cables you tried, did you try shield and non-shielded? How long are the cable runs? I only have unshielded, the runs are about 20m. But I tried with short 3m patch cables same result.

If you're struggling to get it to show in netinstall, try an isolated switch in between. Struggled for an eternity with this then put in a call to LinITX my local supplier, and they suggested timing of the port on windows might be an issue. Put a switch in and it showed first time.

Guys,

domonic. Thanks for taking the time to post this, I figured it was something like this but not had time to investigate fully and log it as a bug.

Rule 4 is for your input chain, so traffic with the router as it's destination. Since you have a NAT rule, the src-address is different and therefor the forward chain should be hit.

Doesnt ether1 on some Mikrotik's have some sort of PoE feature? Perhaps that is causing negotiation problems?

Look down the spec list here: http://routerboard.com/RB2011UAS-RM

Does it work ok if you use port 5, commonly used as WAN2 on Mikrotiks?
