Proxy-Arp Issue

I have a situation were I have many users accessing a gateway to the internet working just fine with "no ip proxy-arp" on the gateway interface. Then I have one user that cannot access the internet unless I allow "ip proxy-arp". Even when this user cannot access the internet, I can ping her dlink router ok from a remote network. Removing the dlink router out of the picture does not seem to solve the problem. DNS servers are on a remote network. Thanks in advance.

Re: Proxy-Arp Issue

We'd have to know more about the topology to give specific advice. But in general, proxy-arp is an ugly hack that allows a broken network to function as if nothing is wrong. It can "fix" situations in which a client's subnet mask is wrong, or default gateway is wrong/non-existent.

So I'd check the IP configuration & routing table on the Dlink for starters.
