The most robust way to bridge LocalTalk and EtherTalk networks is via the old software router from Apple: "Apple Internet Router."
To use it, you are best to run an early System 7 on a 68030 or 68040 Mac, and you need a machine with both LocalTalk and ethernet network connectors (like a 540c).
It is very stable, running for months without attention -- and though much the same thing can be achieved with hardware bridges, I have found two of the latter to be flaky by comparison, requiring restarts, etc.
The free LocalTalk Bridge, which has been mentioned, is essentially a cut-down version of Apple Internet Router, the latter being the high-end implementation of the routing software. It is one of the handful of products that can give you AppleTalk Zones, btw.
