I wonder if anyone can offer some help?

I'm attempting to setup port forwarding on a couple of routers (NetComm 304N-NZ & D-Link G604T) - one at my home and one at my business partners place in Nelson.

Despite the fact that we are both using different ISP's Xtra & Telstra), we're both unable to get port 3283 working correctly. Also port 22 (ssh) doesn't seem to respond if I ping a machine on his network (set as a static IP on his LAN).

The problem is also reciprocated at my end - 2 different ISP's, 2 different routers, but the same issue?

Any help would be much appreciated.
