Pfsense shows gateway is offline but the gateway is online

pfsense wan receiving echo requests but not responding
not connecting to internet
when i try pinging this happens
packet capture data
ARP, Request who-has 192.168.10.1 tell 192.168.10.175, length 46
18:34:39.123786 ARP, Reply 192.168.10.1 is-at 28:3b:82:fb:9a:e0, length 46034413
put cmd prompt says request timed out .192.168.10.175 is my pfsense wan ip and 192.168.10.1 is default gate way …192.168.100.10 is pfsense lan ip …192.168.100.1 is host ip

what can be the problem

A guess would be that this is enabled which is the default.
