That claim is complete nonsense, of course; and the router is most definitely misconfigured. > I also can't seem to get out of the intranet via the Linux diald machine.

See if packets from the srv2 actually pass over that interface. If yes, you just suffer from the ISP's routing problems. If no, you also have a local problem. Next, do the tcpdump on eth0 to see if the packets make it to srv1. If yes, the problem is routing on srv1; if not, it's routing on srv2 (probably a missing route for default to srv1). > I have created some accounts for generic testing.
