Proxy server flodded by requests on port 53 & port 25


hello there.

we have a proxy server Mandrake 10.0 connecting about 1200 windows clients. Some virus is spread in network which is flooding proxy server on port 53 & port 25. The firewall is dropping these packets which i can see in shorewall's log.

The proxy server do not hang but its the switches in the network which get hanged... n the switches have to be restarted...

Sometimes we also get an error: "Neighbour Table Overflow..."

Please tell what can be the solution? how can traffic requests be stopped.... which may prevent switches from being hanged up...

Thanx
Saurabh Sahni

The only solution I can imagine would be to simply clean up the clients.
