I have a problem with connecting 2 offices across the internet. I have setup 2 new servers zentyal to zentyal. 1 is the main server, which is also a web mail and file server, the other is a slave. But I can't get the vpn to work, I've been tearing my hair out. I've found similar problems on these forums and I think I need to modify some tables but I'm not sure what the problem is. I can't resolve 192.168.160.0 to 192.168.0.0, the advertised network not work. I've tried tun and tap, firewall rules, staic routes, L2TP. All to no avail.
here's a copy of the routing table
