I have used various versions of shorewall on older Linux servers with great success. I have recently replaced one of our old servers with CentOS 6.6 and installed Shorewall 4.5.4 from the epel repo. Please find attached the Shorewall dump file as requested on your support page
When I try and use a DNAT rule to forward pptp traffic to a Microsoft ras server (which was working in a previous version) The client connects and authenticates on port 1723 and a VPN session is established but no protocol 47 traffic is recorded by Shorewall and I am unable to communicate with any computers on the local network. Client source ip (in the dump) 85.255.233.8 Shorewall server eth0 (net) 157.228.196.187 Shorewall server eth1 (loc) 10.1.0.6 Microsoft RAS server 10.1.0.10 I have also opened the L2TP ports but the same happens, I connect and authenticate but no traffic is send over protocol 50 Any help would be greatly appreciated Gary
