DigiOne as serial bridge..plz help

I am trying to use the DigiOne IAP as a serial bridge between the PC connected serially as RS232 and the other DigiOne connected to a RS485 serial device. I have assigned static IP addresses to the two DigiOnes and the PC to configure them .All the instructions have been followed with the web browser using the Peer to peer with the network port to be with the other Digi IP address and the default port as 2101. but still when I try to communicate it doesn’t work. I tried to configure through the CD, the first device is configured but the other doesn’t show in the list. What am I doing wrong in here. Please help.
Thanks a lot.
