No, routed is not running on FreeBSD.  Both FreeBSD and Proxy
are at the same level in the networking heiarchy.  Proxy is
multi-homed (10.0.0.1 and 161.X.Y.250) and acts like a
gateway to our internal network. FreeBSD, which has a single NIC
(161.X.Y.251), serves up our WWW.  Both servers are connected
via a hub to our ADSL modem, and have the same gateway which
is 161.X.X.1.  So I guess my point to all this is that I don't
understand how NT could be sending false routing information.

Perhaps somthing else could be happening higher up at our ISP.
The only thing that confuses me a bit is that the when when
the http server appears to be down from the outside, all we need
to do is either reboot FreeBSD or (as I have just discovered)
start tcpdump running and the service is instantly restored.

I by no means claim to be a networking guru, so there are likely
issues to which you are referring that I do not understand.

I will defenitely give this a try when it happens again.

Thanks for your reply.
