I have an x86 box running ros 4.5 set up with a dhcp server that adds arp entries and the lan interface set to arp-reply-only. Everything was working fine until we had a power failure. Upon resuming power there was a portion of our clients who were not able to contact the router despite having active arp entries in the router.
I was not on site and not the person handling the issue so I was not able to take advanced troubleshooting steps to isolate the exact problem. Changing the interface to arp-enabled fixed some of the clients, and removing the existing (dynamic, added by dhcp) arp entries cleared the issue for the rest.
Has anyone else had an issue like this or can anyone provide information on why this happened?
I would like to re-enable arp-reply-only but not in fear that my clients will be unable to use the network after a power outage.
