Hi Sir,
I'm troubleshooting an issue.
An FTP server is connected to a router with proxy ARP disabled. Local hosts can FTP to this server, but remote hosts fail to FTP. However, remote hosts able to ping to the FTP server. I've verified that no ACLs are configured on routers' interfaces along the IP path that deny FTP traffic.
Is there a possibility that disabling proxy ARP causes the problem? If the same remote host can ping to the server but can't FTP, this already isolated network layer and lower layers issue, and disabling proxy ARP should not be the cause of the problem.
It is unknown how the server is configured, whether it's pointing gateway to the router or it relies on proxy ARP. If it uses proxy ARP, pings from remote hosts should fail by right. Any thoughts?
Please advise if you've seen a similar scenario.
Thank you.
B.Rgds,
Lim TS
