Can’t establish why a gateway becomes unavailable

[desher]

Hello Everyone

A little clarification, I’m new about OS X and expecially his server version, so don’t hate me if what I’m saying sounds like pure, noisy words from a noob.

I have a couple of servers (one OD master and his replica) and some clients that are connected to their shared directory.
We use a Linux distro (Zeroshell) who acts like a captive portal and it’s the default gateway for my clients. Both 10.6 servers are valid DNS for my clients.

Here comes the issue. From time to time, both servers or client looses temporarily their connection with this Linux gateway. Performing a ping results in a request timeout.
the same request timeout occurs if I perform a ping from the Gateway to one client (or server) that is struck from this odd phenomenon.

I’ve never found abnormalities pinging other machines.. windows clients, windows servers, osx clients, osx servers.. even another linux gateway (Debian). Non-osx machines appears to be immune at the problem.

Another detail. I’ve moved one of my 10.6 servers in the same switch of the gateway, and the problem disappears. Obviously it’s still an huge problem for my clients.

Thanks in advance
