L2TP VPN Client Limit on Level6

RouterOS General
1

Greetings Everybody

I know this might have been asked and answered before but i could not find it on the forum thread.

I have 20 x L2TP-Clients on a CCR router but only 16 Sessions are connecting at a time.
If i disable 4 from any of these working 16,the other non working 4 would connect.

I also did the tests by configuring these 4 non working ones on a small mikro daisy chained to the main one and they connecting right away (so just to rule out that the VPN provider is limiting the sessions per public IP).I also connected to another VPN server IP from that provider but still same problem.


I checked the logs (in attachment) and i notice something like:
Error-Message=“Reached configured max-sessions per tunnel limit”
Is that a limitation of the RouterOS Platform?
Anybody ever had a prob like that?

thank you very much.

I see on Mikrotik under l2tp-server you can configure “max sessions”, maybe the VPN provider did?

Just curious, why will you create / connect 20 x VPN clients to the same VPN provider from 1 device?

hey thanks for your reply.

These are all unqiue username/password for each VPN Client,so i dont think its being limited due to that.
Also i dont think the ISP is running the VPN service on routerOS but some custom made server.

That said all my tests make me think that somehow i can not push more than 16 L2TP Clients on a mikrotik.

I even tried the latest stable RoS or the release candidate one.

Thanks
D.

Error has nothing to do with your router. Remote server sends this error, so you should ask provider why this limit is reached.

What I was trying to hint towards, is that if it is available in Mikrotik, then the “Standard / RFC” obviously “allows for this by design”, so does not matter if ISP is using Linux, Cisco, Mikrotik, or what ever, the options is there as per RFC and maybe they configured a max session limit on their side and you should contact them
