The networkconfig.h files sets the struct rtems_bsdnet_ifconfig's ip_address field to different ip addresses (from the programs below 192.168.1.15 for the server and 192.168.1.66 for the client. So that should be ok.

Stupid question.. is it possible that both RTEMS boards are configured
to use the same IP address?
