I cannot send you a settings file because that contains passwords that I use for the services on my A4000T. However, I do have some questions and suggestions:
How are you connecting the machines together? Are you going through a hub, router, or switch? Or are you connecting the Amigas directly to one another? (If thru hub/switch/router, you need standard CAT5 cable. If direct connection, you need a "crossover" CAT5 cable.) What kind of cabling are you using? Are you sure the cables are good??
Here's an example of the settings for a direct connection setup (this also applies if you're using a hub with standard cables):
A1200 #1 - IP = 192.168.1.1, SubNet = 255.255.255.0, Gateway = 192.168.1.2
A1200 #2 - IP = 192.168.1.2, SubNet = 255.255.255.0, Gateway = 192.168.1.1
--------------------------------------------------
Example setup with a network switch in between the two A1200's ... the same goes for a router (if you're using a hub, then use the direct connection config above, but you will need standard cables, not crossover):
Switch LAN IP = 192.168.1.1
A1200 #1 - IP = 192.168.1.2, SubNet = 255.255.255.0, Gateway = 192.168.1.1 (switch LAN IP)
A1200 #2 - IP = 192.168.1.3, SubNet = 255.255.255.0, Gateway = 192.168.1.1 (switch LAN IP)
