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

Hi Tony,

One thing I notice is that the subnet mask for the internal NIC on the SBS
2000 server may be incorrect. Your 10.1.1.1 IP address is for a Class A
network which normally would have a subnet mask of 255.0.0.0 rather than
255.255.255.0 (as with a Class C network => 10.0.0.1).

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
