RE: VPN through DSL

My company uses the same Nortel client. I run it behind a Linux/IPTables
packet filter utilizing NAT. It works great.

Most likely it is the DSL provider.

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!
