I know a little something about getting a Nortel Access Client (on a Windows
platform) to work accross a NetBSD router.
It appears to me that the reason your cable / satellite connection gives you an
error could be due to your ISP mapping MAC addresses to new IP's.
I know from experience going through IPNAT will NOT work with the Nortel Extranet
Client. The IP address that the Client machine is assigned MUST be the address
that the Extranet switch gets. Otherwise, it's considered something like a
security threat, and is not allowed to pass.
I also could not get the Nortel Client to work over a DirecPC (Hughes) satellite
connection either (and tech support at Hughes told me it wouldn't work.)
I don't know if this has to do with IPSec or just the way Nortel implemented
I would talk to your ISP about the Nortel requirement, and see if they could
assign you a set of Fixed IP addresses to use (these can be assigned via DHCP.)
