Re: MTU troubles using IKEv2 providers like NordVPN [work around]

When I temember it well you use the DoH client in RouterOS to connect to Cloudflare. This DNS DoH traffic is not passing through the VPN because only your client IP 192.168.0.5 is using only the VPN. The shortest way for now is to use the dynamic DNS server of NordVPN and disable DoH. This if you d...

Re: MTU troubles using IKEv2 providers like NordVPN [work around]

Hmmm strange, then I am able to browse ipleak but gets this.
Does the proposal for the action=none fragmented ICMP policy has to set to the vpn proposal or just leave it as default?

Re: MTU troubles using IKEv2 providers like NordVPN [work around]

maybe the MTU has to be changed to make it work? My pppoe MTU is 1480.

Re: MTU troubles using IKEv2 providers like NordVPN [work around]

I have to think about that and my first answer was not correct if you address range is 192.168.0.1-192.168.0.255

Update: I can't place the first line:
/ip ipsec policy
set 0 disabled=yes
the first one is disabled by itself

I've setup a Minecraft server on my rb2011, my MC server can be accessed outside LAN using DDNS address, but couldn't access from LAN using ddns. Using canyouseeme can see my mc server port. I've set a hairpin nat in my firewall but it doesn't seem to do anything. # jan/24/2020 02:26:00 by RouterOS ...
