Hi,

I have a strange problem with 2.4.14.  I have a client and server
application where the server is bound in INADDR_ANY of a TCP
port.

It accepts connections off multiple network interfaces.  However
it also needs to receive connections via Loopback.  Here's the
problem, if we physically disconnect the interface which happens to be
our default gateway, connections to the server via loopback
begin to fail.

If we bring the interface down administratively using ifconfig,
then the connections to the server via loopback work again.
Is this the correct behavior ?

Yan
