I've got a strange issue connecting a remote CentOS server to the built-in OpenVPN service on my CRS.
OVPN is working fine on all connected client PCs. Now I wanted to connect a remote server to this network (to give it access to a certain network service).
I've uploaded the config, CA cert etc. and everything seems to work - BUT in fact both sides can't reach each other even though the tunnel is up (according to openVPN).
I've double checked everything, credentials are ok, there are no firewall rules blocking and when downloading the complete config to my Ubuntu notebook it works like a charm. I can also see that connection has been established in RouterOS
Anyone got an idea what I'm missing?
The only thing I could think of would be some sort of incompability (server's running CentOS 6.x) but I think that's very unlikely - especially as the tunnel is created successfully.
