Use to be able to VPN/RDP. After installing SBS2003, can only VPN

[TonyG]

Hello.

If i plug my computer at home (WIN XP Pro SP2) directly into the cable modem, i can VPN and RDP to my office without a problem. Office setup: (SBS2000 SBS2000 server, 2 nics, Zyxel Prestige 650 ADSL Modem, Zyxel Zywall 10 firewall 192.168.1.1, External nic: 192.168.1.2, Internal nic: 10.1.1.1, ).

I brought home a Dell server, installed SBS2003 Premium, SP1, no ISA, two nics(Internal:192.168.16.2, External:192.168.2.15), Linksys router(192.168.2.1), Belkin switch and plugged cable modem into Linksys router. I also plugged the home computer into the Belkin switch.

Everthing works fine, server and home computers can access internet and email just being plugged into switch, not really logging onto server, just staying local.

Problem: Workstation that was able to VPN/RDP, can now establish VPN but cannot RDP. Message "The client could not connect to the remote computer" comes up.
Cannot ping 192.168.1.2 after VPN is established on workstation
Cannot Open

http://SBS_IP/remote

in Internet Explorer after VPN established on workstation
PPTP Passthrough is enabled on Linksys router
Ports 47 and 1723 are being forwarded by Linksys router
I have run CEICW numerous times
There are no errors in the event log after attempting this

If i plug home computer workstation into Linksys router or cable modem, I can again VPN/RDP. Once i put it back to switch on network, VPN OK but cannot RDP.

I am trying to RDP to the same server that i am VPNing to.

I have included IPCONGIG /ALL for home computer, home SBS2003 server and office SBS2000 server.

I have been trying to fix this problem for weeks now. Any help would be greatly appreciated.

Thanks,
Tony

I'm assuming you are using pptp vpn. Question, can you record your IP? Go to a computer at work or a friend's house, telnet to that IP, using port 1723.

In Windows 2000, a successful telnet session will show a very brief connection and then a flashing cursor with no prompt. I suspect it should be the same with XP.

If you don't get that, try hitting the factory reset button on the router and reenter your settings. Still no go, update the firmware.
