SBS2K3 single NIC 2wire 3800HG router with Uverse

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

I just recently changed ISP from a non att dsl with statics to uverse with
dynamics. Everything is wroking fine with port forwarding and dynamic dns
except that clients including smartphones can't access the server using the
external url. It appears that the 2wire router will not route to itself so I
think the solution would be in changing some things in the SBS dns to solve
the problem. everything else works fine including VPN to the server just this
quirk from inside the network


1) From outrside our house I can access the server for example via
https://server.company.net/exchange. Even the smartphones can sync from
outside.
2) However, I can't get that to work from inside. I can ping from inside
server.company.net and it answers with the public ip address. Yet I can't
open https://server.company.net/exchage from inside. However I can open
https://companyserver/exchange in this case companyserver resolves to the
internal ip address 192.168.0.2 and server.company.net resolves to the
external ip address.

I think the problem is that the port forwarding is working from outside the
network and forwarding the ports to the server, but it is not forwarding from
the inside. Its not a huge issue, just that when a smartphone is connected
via active sync it can't reach the server. I obviously need to keep the
servers address in the phone as the public version.

THe sbs server is the dhcp server and default gateway for the internal
machines. Is there a way to put an entry in the dns tables to solve this?

Any thoughts would be helpful.
