Hi Peter,<br><br>Thanks for the help :-)<br><br>It is good to know that the connection is active, just have to figure out where it is failing.<br><br>I am using shorewall as a firewall and it is running on the hosts that I am trying to tie together. Because the connection appears to be established from your comments I am assuming I have the rules set correctly for the connection.
<br><br>I have tried pinging and ssh'ing between the hosts using the internal addresses and get no response. I have also now tried doing the same thing from hosts in each of the private networks and get the same result.
<br><br>I have cleared the shorewall configuration of all zones/interfaces that related to a vpn based on your comment about the data going to the external interface.<br><br>My shorewall configuration looks like the below:
<br><br>root@zulu:/etc/shorewall# cat zones<br>fwall firewall #<br>loc ipv4 #<br>net ipv4 #<br><br><br>root@zulu:/etc/shorewall# cat interfaces
