Huh, I assume that we are talking about Apple's LocalTalk Bridge
software for the Mac. Let's go back to the beginning on this one.

You can't run IP directly over LocalTalk cabling. If you need to run an
IP app on an old Mac, MacTCP or Open Transport network software both
support MacIP where IP data is encapsulated in AppleTalk packets. When
the MacIP AppleTalk packet is read by a MacIP server (or router), it is
converted back into IP for transmission onto the main IP network. In
reverse, IP data addressed to the old Mac from hosts on the main IP
network is encapsulated in AppleTalk packets by the MacIP server.

LocalTalk Bridge is not a particularly fussy piece of software. It
assumes that any AppleTalk traffic from the LocalTalk network should be
redirected onto the main ethernet; LT Bridge is quite happy to redirect
MacIP AppleTalk packets from LocalTalk onto the ethernet. Therefore if
using LT Bridge, you should view your network as a "flat" one composed
of ethernet; your MacIP server should be on the ethernet network.

I've had all of the above working with an SE/30 running LocalTalk
Bridge and IPNetRouter (which can act as a MacIP server) to connect Mac
Plus and similar to the internet.

Is this all off topic? No, Marinetti has been demonstrated running in
MacIP mode so it should be possible to connect a IIgs to an IP network
over LocalTalk.
