proxy-arp

[Jon Otterholm]

Hi.

I have a problem with proxy-arp entries.

If I add an arp-entry:

arp -s $hostip $routermac permanent pub only

the router sends an arp and replies to it's own arp like:

15:40:02.074419 arp who-has $hostip tell $hostip
15:40:02.074663 arp reply $hostip is-at $routermac (oui Unknown)

This is a problem because some clients interpret this as an ip-address 
conflict.

In my case the router answers for arp on a bridge where all clients have 
their own member-interface and clients are prohibited to talk directly 
to each other.

Have I completely misunderstood the proxy-arp function? IMHO the router 
should only answer to arp for $hostip to other clients than the one that 
actually have the ip-address.
