Rob, Your client is the same version and build as mine. Could you establish a tunnel with your network and open the connections properties (double click on the Nortel icon in the system tray) and check to see if 'IPSec Nat Traversal' is enabled?

It comes to me prepackaged from my corp's IT group. It does say it is the Nortel Contivity client. I don't know about the options for it, as it came prepacked. Is there a config file or an .ini file I can send you?

-----------------------------------------------------| Afternoon, I saw this message and had to ask, are you using the client for the Nortel Contivity switch? (VPN Client v4.10d) If so, what settings are you using to get through the NAT problem? I'm trying to use it through a OpenBSD ipf/pf firewall on a cable modem at home and the only message I get from the client is that the switch is not responding.

I run it behind a Linux/IPTables packet filter utilizing NAT. It works great. Most likely it is the DSL provider. ~Rob Roberson --------------- On Wed, 13 Mar 2002, Peter Lukas wrote: Sounds like your VPN software runs on your client machine and your DSL router is running NAT. This will cause problems for most any VPN connection. It is also possible that your provider is blocking certain protocols required for VPN connections as Jeffrey points out. Verify that your DSL router is running NAT and investigate options to obtain static IP addresses for your client machines from your provider. Short of that, you'll need to determine whether or not your VPN software can be used behind a NATed connection. Good Luck!
