When I ping from EC2 from Server VPC to EC2 in WAN VPC, I saw the following arp request. I do not understand why

appreciate any insights !!

Accepted Answer

Looking at the route table in the screenshot you shared I see there is an entry for 10.2.0.0/24 with local route (gateway 0.0.0.0).

This is the reason why the instance attempts to directly ARP resolve the 10.2.0.35 IP address instead of sending it through the next-hop gateway.

I'm not sure how that entry got in your route table but one you will get rid of it I expect the problem to be resolved.

I did the following:
route add -net 0.0.0.0 dev eth1
Strangely, the second day I noticed it worked.

thanks a lot !!
