I am setting up a FreeBSD 2.1.7 box as a gateway for a local
network. I'm having a really odd problem (it seems to me) that
I can't figure out: When the gateway boots, the first machine
on the LAN to contact the gateway can connect, see the internet
at large, etc. but any other machine on the network cannot.
The gateway says arp lookup failed: host not on local network.
It can be any machine on the network - IP address, OS, etc.
all don't seem to matter.

The routing tables look normal to me - a default route to
the ISP, various routes to various nonlocal networks,
a route mapping the incoming line (from the ISP) to the
ethernet card on the local network, and then the ip<->
ethernet route for the first lucky machine to connect.

Has anyone seen this before? Help!

Thanks much.

Harry

PS - please cc me: I haven't subbed to the list yet (have to
get this working first!) Thanks.
