[SOLVED] Routing/IPTables Question

Posted by kbocek on 2012/3/26 19:05:44

With the help of forum members I successfully moved a server off the net and behind a new router/gateway. My network looks something like:

         LAN
  ws1  ----+
           |
           |
 server1---+--Gateway1-- Internet
       ^              ^
     x.pvt       x.mydom.com

The server hosts a handful of services including web and DNS. I have a pseudo-domain for my LAN called PVT (served by server1.) NAT internet access from the 10.0.2.0 LAN is working just fine: all workstations and hosts can get out without a problem. Port forwarding from the gateway back to server1 is working just fine. I can access all services on server1 from the LAN just fine.

My problem is that, for logical consistency, I would like to be able to access server1 from ws1 using the external address. That is, want to surf the server1 web server using x.mydom.com. Right now this fails. I can surf it using x.pvt but *not* x.mydom.com.

Hosts external on the net *can* access this server. Just LAN hosts fail. I assume I mis-configured IPTables somehow and NAT and port-forwarding on the gateway are conflicting somehow.

Does anyone have any thoughts?
