Mark:

route -n yields
Destination    Gateway       Genmask        Flags    Metric    Ref    Use IFace
24.159.200.0   0.0.0.0       255.255.252.0  U        0         0      eth0

"route print" on Windoze yields:
Active Routes:

Default Gateway:      24.159.200.1

where "24.159.201.xxx" is the leased IP.

Thanks for any assistance.

Since that system is my firewall box it is really important that I get it running again. Note that I get the same symptoms with or without the firewall running.
