| Alter your natd_flags to something like
| "-f /etc/natd.conf -redired_port tcp 192.168.0.1:80 80"
| (this will direct anything that comes in on port 80 to 192.168.0.1 ... see
| the man page for natd for more details on the syntax)
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
I'll let you know when I get an answer.

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