We use a lot of netgear FVS318 routers on our wireless network as cheap vpn and client routers. The network gateway is a Redhat 9 Server with IPtables. We are finding that when a client with an FVS318 router (latest firmware) is accessing the web the router is asking 3 times for each ARP request, typically the linux router, while there is traffic going across that link the router is continuously asking for the same ARP inforamtion.
We also have many Netgear RP614 and FVL328 routers, however they do not exhibit the same issues.
As we have a lot of the FVS318 routers and each client has a lot of data across their connections the ARP traffic is huge.
Any ideas ?
