MP-RAS Unix Networking Setup

I have an MP-RAS unix server from ncr. We are trying to get the network configured so that we may transer files between the unix box and a pc. I have used the included TCPCONFIG command to setup the network, however I can not ping, telnet or ftp to any other pcs on the network. Any help would greatly be appreciated. Below, is a diagram of our network (to the best of my ability) and some commands that I can think of. If you need anything else to help me diagnose the problem please let me know.

Router (192.168.1.1) connects to a switch which connects to 2 pcs and the unix box.

ifconfig -a shows:
en2: flags=4043<UP,BROADCAST,RUNNING,MULTICAST> mtu 8232
inet 192.168.1.129 netmask ffffff00 broadcast 192.168.1.255

netstat -rn shows:
