VPN Client and FireBox II

D

Dumitru Ozunu

Hello again,

I have a problem using a Nortel VPN Client. I'm using a W2K SP4 machine, the
VPN client v04_61.18 installs without problems, I'm using a softoken, but
the connection fails (the user grup and password are correct, the UID and
generated softoken are also OK). I'm trying this since 1 week and is driving
me nuts.The W2K machine on which the Nortel VPN Client runs is behind a
Firebox II thing. What should I do to have the client run? Here is the log
file from my VPN Client (I think there is a problem with the NAT, please
help...

as I've read in the help file, there is a problem with the NAT Traversal and
I have no ideea how to configure the FireBox II stuff...the problem is by
the FireBox that lies behind (NAT Traversal doesn't function properly, i.e
the client finds the server but then the server cannot find back the calling
client)
Does anybody have some experience with this problem, i.e. Nortel VPN Client
and FireBox II
from WatchGuard?
thanx again,

I've got several FB-II units and found that many vendors VPN Clients do
not function well. This is not specific to WatchGuard, it's about the
same with many vendors - if you use the WG Client it would work, but
that probably is not possible?

One other thing - the subnet that you are using on your end can not be
the same subnet that's behind the firebox.

If you can't get it working, do a PPTP connection to the FB itself.
