I'm a bit confused here....

Are you saying that you change the network connection on your _work/office_
mac to LocalTalk as well as your home Mac? if so, why? Why not leave the
Mac connected to ethernet as is, presumably with a Static/manual fixed IP

Using Peter Lewis's PD MacTCP Watcher will give you the IP number of your
home connected machine.

I have had no trouble getting an ARA type remote connection to support
CU-SeeMe, with a fixed manual IP number, through Apple IP Gateway.(same
also with SLIP/PPP on Mac and under Windows). If only TIA supported
