RE: Can't Connect to Remote Desktop on External Network

Let me clarify or restate the issue.
Before installing a second NIC and ISA Server/firewall 2004 on MY SBS 2003 -
i.e. when I only used one NIC on MY server and not ISA firewall - I COULD
connect to 2 different EXTERNAL netorks (SBS 2K, SBS2003) using VPN and
Remote Desktop on MY workstaion.

Since installing a second NIC and ISA Server/Firewall 2004 on MY SBS 2003
server I CAN NOT connect to these same EXTERNAL networks using VPN and Remote
Desktop.

Yes I reran Email and Internet Connection Wizard.
Yes ports (1723, 47, 443, 444, 4125) are forwarded on my router and the
routers of the networks I am trying to connect to.

Here's my IPCONFIG info:

Hi Dan,

Thank you for posting in SBS newsgroup.

I am sorry for the delayed response due to weekend. Please understand that
the newsgroups are staffed weekdays by Microsoft Support professionals to
answer your systems and applications questions. Your understanding is
greatly appreciated!

From the description, do you mean you can not RDP to LAN of SBS from
external network or you can not RDP to external network from SBS and LAN
client computer?

To narrow down the problem, would you please help me confirm the following?

1. Have you rerun CEICW?
2. Can you RDP to SBS or other computers directly through click Start and
Accessories and Communications and Remote Desktop Connection?
3. In Internet Explorer on the workstation you are connecting from, go to
Tools, Internet Options, then click on the Privacy tab, remove the check
for Block pop-ups.
4. Double check if you have selected Allow users to connect remotely to
this computer on the Remote tab of properties of My Computer on SBS server
and the computer you want to connect to.
5. This issue can also occur if you are connecting from an Internet
computer and your router does not have incoming TCP port 4125 opened. If
this is the case, all connections from LAN computers should work. I suggest
you check to make sure the incoming TCP port 4125 is opened on your router
or hardware firewall. For more information regarding a similar issue, see:

828053 ISA Server prevents connection to a remote desktop when you connect
http://support.microsoft.com/?id=828053

886209 Users cannot connect to remote desktops by using the Windows Small

I appreciate your time and look forward to hearing from you.

Best regards,
