Has anybody got the above configuration working? We've put the hardware together but get "Local host or gateway not responding" when we attempt to use the Mac telnet to talk to anything on the other side of the PC router. The PC router log shows a "Localtalk arp lookup on <Localtalk IP broadcast address>" but nothing else. I'm reasonably sure that the telnet and router have been configured correctly. I've got sources for both the PC router 2.1 and the Mac NCSA Telnet 2.3 and from my incomplete understanding of the code I'd expect them to be able to talk to each other (For example, both use Appletalk DDP socket 72). We're not trying to do Mac IP address resolution. Our configuration: PC, Mac, Unix boxes -(Ether)-+- Novell 2.15c server --+ | | | +-----|----+ +-Cisco-Internet | +--------+ | Mac's -(Localtalk)-----+---?--- PCRouter 2.1 -(Ether)-+ ie. We have two networks in the department, one running TCP/IP and Novell Netware IPX over ethernet and the other running Appletalk/Appleshare over Localtalk. We would like to run TCP/IP over the Localtalk gatewayed via the PC router to the local ethernet and to the Internet. We're already successfully running the PC's and Mac's over ethernet to the PC router. I suspect this is an old problem but I'm running out of places to look and help would be *much* appreciated. Also, does anybody know of a ping or netwatch for Mac/localtalk? Please mail. If there's enough interest I'll post a summary.

Its default gateway should be the cisco and the LocalTalk Mac's default gateway should be the PCRouter. What's the line descending just to the right of (Ether) in your diagram? Has the PCRouter got 3 interfaces (1 LocalTalk and 2 ethernet)? Also, has the server got 2 ethernet cards and a LocalTalk card or is it sitting on a "T" connector on a coax that runs from the PC, Mac, Unix boxes to the cisco?

I can't add anything to the discussion, but I have a request. PCRouter
sounds like something we are looking for here I assume it's a piece of
software to run on a dedicated machine to keep pc-lan traffic off an internet?
Something like this?
[PC]---[PC]---[server]---[xt running pc router]-------[Other hosts, etc]
(All ---connections are ethernet)
And the PCRouter keeps traffic like pcs trying to run pc applications off
the server from going to the other hosts, but allows things like mail, ftp,
and telnet packets that should go outside the PClan through.
Am I right? Does just the PCRouter station get a node address?
(ie, would the LAN just have one mail address -- eg) user@PCLAN@domain)
If this product does that, or anybody has recommendations for one that does,
Please e-mail me. I'll post or mail results if desired.
Thanks
Dave
