The situation is this, and I’ve tried to hunt a solution online, just haven’t found it in the many threads out there.
I have one head office, running 3 LANs, now with 2 WANs, with 4 remote branches connecting via L2TP VPN.
Everything worked fine, until I added the second WAN.
I have routing marks in place to send the relevant LAN out the correct WAN.
Inbound NAT rules are working as expected
The only thing that isn’t is the VPN traffic. Not sure why this has stopped working nor how to go about fixing it.
I’m sure its a route mark of sorts but I’ve tried a few things and no luck so far, any help please
Not enough information for such a complex setup and weird trouble. To allow someone to help, you’ll have to post the output of “/export hide-sensitive”, and if you are extra sensitive about privacy, then also edit, before posting, the public addresses if they occur in the configuration, in a systematic way (so WAN address 1 is replaced e.g. by A.A.A.A everywhere and WAN address 2 is replaced by B.B.B.B everywhere, the best way is to use Find&Replace functionality of a text editor).
To add to sindy’s post, also let us know what of the VPN is not working, i.e. VPN’s do not establish, or no routing across VPN’s, can reach HO via VPN but not other remote sites, etc
