Hmm, no good for the current set up, I'm not trying to redirect port 80 no
more, I just
want to have 'this' port 80 available. Web Server on FreeBSD router machine
And DNS updater program is also on router machine.

| I've seen this before.  A lot of ISPs are using private IPs for a lot of
| their routers and hop points.  If everything is configured properly, it
| works OK and doesn't cause problems (that I've seen) but ...
| Get your testers to try traceroutes to see how far traffic is getting.  I
| an ISP once that had an endless routing loop in one of their routers that
| took us a week to convince them wasn't our mistake.
| Also ... can the testers connect via IP or hostname?  Can they ping Ip or
| hostname?

I'll let you know when I get an answer.

| The results of ping and traceroute tests above would help narrow things
