    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.

    Thanks Cris,
    However, how to configure the smartphones? When they are connected via
    tethered activesync, they can't find the exchange server. They obviously need
    the external address when they sync over the air from ourside the network.
    When we had two nics this wasn't an issue.
