The PM-2e-R has a router built in and so 204.50.3.2 is the address of the
router as well as that of the terminal server. FYI following is the route
table and netmask dump from the PM2e-R :

enola> show route
Destination Mask Gateway Source Flag Met Interface
----------------- ---- -------------------- ------- ---- --- ---------
0.0.0.0 0 207.107.201.69 local NSC 1 frmW1
207.107.201.68 30 207.107.201.70 local NL 1 frmW1
204.50.3.0 24 204.50.3.2 local NL 1 ether0

enola> show table netmask

207.107.201.70 255.255.255.255

The WAN port on the Livingston is at 207.107.201.70

Thanx again
