Huge Arp Cache - Neighbour Table Overflow on IPCOP
Hi,
I'm using the latest IPCop-FW, Linux-Kernel 2.4.
During worktime the arp-cache on the FW rises up to 4000 entries. I see several remote internet-hosts with the MAC of the nearest router, the default gateway of the FW. This behaviour leads to extreme packet loss. The "Neighbour Table Overflow" warning ist logged.
Our corporate network consists of less than 10 workstations, so this cannot be the reason to make this cache so huge. I doubt, that there should be any foreign hosts in the arp-cache.
Regards, Thorsten
