From using traceroute and ping I have concluded it is the
server that is breaking the chain between client, server and router.
I can’t think of what is stopping the server from
forwarding data from the client to the router. I might do some packet sniffing
to see what is going on.
If you guys could offer some advice, I would be glad.
Here is some route and firewall data in case it holds the
key to the problem:
