I will collect this info when I'm back in the office. What I do know is subnet mask is 255:255:0:0, and the gateway is 172.25.218.3. It seemed to me that the router contains an ARP cache (as might be expected), as even when I deleted the cache on the PC used to issue the ping an ARP was not generated on the far side of the router, so the router must have provided the necessary information locally. I got around this by simply changing the MAC and IP address of the ARM7 board but it does show that the router is doing something at least.
