OK, looks like IPSec did not work out of the box for our needs, happy to look into this further however looking for a solution. Now looking at OpenVPN as an alternative.
I have created an OpenVPN tunnel on port 1195 however when I check this port it is not accessible. Do I need a firewall rule to open the port or should this be done automatically?
In the list of services I can see OpenVPN@host-to-net is stopped on port 1194 however should there be a service for OpenVPN@net-to-net?
Please have a look at the logs. I don’t use VPN, but I think there should be an openvpn.log, if not you have to look at messages.log. Please post the errors.
