Cisco VPN client and ISA2000 on SBS2003

I'm having problems connecting to a Cisco UBR900 on my customers site since I put ISA2000 in place on my SBS box.  The Cisco client is 4.01 and I use it to remotely connect to my customer's network.  The message I'm getting back is that its unable to connect to the remote peer, which I know is up based on the lack of feedback from my customer.  I believe ISA is blocking the connection, but don't know the ins and outs of ISA.  I did review this thread and modified my configuration, no luck.

I appreciate any suggestions on how to proceed.  

I will mention that I'm running the Cisco VPN client on a Virtual PC session running XP Pro.

You need to know what port need to be open in othe for the cisco to work. Once you know that,
Run the connect to the internet wizard from Server Management Console
and add those ports for Outbound and inbound respectively, that should solve your problem.

The wizard will automatically configure ISA for you.

good luck!

Why don't you just use SBS's built-in VPN client? It's automatically configured for you.

I use SBS's client inbound for my needs.  The Cisco VPN client is used so that I can access my customer's network.  

Anybody know the ports used by the Cisco client?  I believe its ports 50 and 4500.

Jeff,

At this point I'm going to close out this one.  I have another challenge with the Cisco VPN client.  When I did the SBS connectcomputer on my machine, the machine name changed and I've not been able to run the VPN client sucessfully.  I did install it on my Virtual PC and was able to connect.

Also, I had a problem with outbound mail being stuck in the SMTP queue and thought this might have to do with ISA 2000, which I uninstalled.  The Exchange issue is still there in that mail is delayed, and I'm not sure why.  I'm going to go after the Exchange issue first and then come back to the Cisco client issue.
