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

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

Tony,

Just to make sure the connection is like..

XP----SBS 2003---Linksys router/NAT-----Internet----Zyxel
(NAT/Firewall)---SBS 2000---internal lan

Is the IP address you are VPN'ing into the external IP address of the Zyxel?
and is the Zyxel the VPN endpoint or is it passing the VPN (PPTP) traffic
back to the SBS server as the endpoint?

Once VPN'ed in are you able to ping the 10.1.1.1 address of the SBS 2000
server? If so, can you RDP to that IP address?

What IP address does the XP client get once VPN'ed in? Can you post the
output from the XP client of the route print command (after the machine is
VPN'ed in)

Hello Merv.

Considering the fact that the whole thing works and has worked fine for over
a year before i brought home the SBS2003 server, is that really an issue.

I don't think the problem is with the office SBS2000 server, but then i am
not the expert.

I could be way off base here, but as soon as i plug my computer into the
cable modem directly, the whole thing works fine.

Thanks,
Tony

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
