[vpn-help] Connecting to Watchguard from Linux v2.1.7

[tom+shrew at falkensweb.com]

I'm using the above version of the Linux client to connect a Watchguard 
client. 
I got it from the main Ubuntu repository.

However, when ever I try to connect, the log window says:

config loaded for site 'work-vpn.vpn'
attached to key daemon ...
peer configured
iskamp proposal configured
esp proposal configured
client configured
local id configured
remote id configured
pre-shared key configured
bringing up tunnel ...
negotiation timout occurred
tunnel disabled
detached from key daemon ...

and then disconnects.

I've tried disabled my local firewall, and even placing my local machine in my 
ADSL reuters DMZ, to no avail.

Is the Shrew client know to work with a Watchguard device ?
