No, this is local ethernet only. The NIC in the Linux box is an Intel
EtherExpress 10/100 (82559) card. All the Windows workstations use NE2k
compatible cards. There are three 3Com OfficeConnect dumb hubs around
the building.

The Linux box has a 24/7 33.6k ppp connection; it does IPMASQ and has a
Squid for the workstations on the LAN.
