Re: Not responding to arp-who-has
In the global settings check the NAT page for ARP settings, do not forget that Cisco routers have a 4 hour ARP cache and you need to use arping to make sure to overwrite that cache or reset the routers arp cache.
Especially when you have a cluster and start using a different cluster method (ClusterXL instead of VRRP or the other way around), however that is not your case, but when cluster is on there is a chance a Virtual MAC is used.
When using static Proxy arp make sure to always push a policy after adding these commands and check with 'fw ctl arp' to see what the gateway thinks the proxy arps should be.
For sending gratuitous arp's for IP's not on any interface:
goto expert mode and execute below commands, in the second replace the IP and interface to reflect your situation:
echo 1 > /proc/sys/net/ipv4/ip_nonlocal_bind
arping -c 4 -A -I eth0 177.177.177.177
