XP can ping LAN, but not Gateway and internet

[Guest]

One of my workstations just started doing this. I log on to my microsoft
network and can access all local servers and workstations. I can't ping the
gateway (Watchguard firewall) or access the internet. The workstation
worked fine a few days ago. I have tried resetting TCPIP and reinstalling
the NIC and its Drivers. It works great as soon as I move the workstation
outside of the firewall. I have 6 other XP workstations (The exact same
workstations) that are working just fine.
Has anyone seen this before?

Thanks.
