ping from another WAN

[mercy_angel]

I am interesting in how can i ping google dns from another WAN. I tried to use ping-options source WAN_IP

but there is no ping, even with some another wan that have access to internet and it works.

I have set vlan on that interface with parameters which i had from my provider.They test their side and it is ok, so it seems something is wrong to my side.

Pinging from the next hop (the ISP side) is completely different from/to the internet (more than 2 hops away). If it's the next hop, it's a "connected" route so the FGT always has a route.

If you change the source IP of your pinging to have the second wan interface IP toward the internet, it still needs to follow a proper default route unless you have a specific route like 8.8.8.8/32 to the second wan GW.

Since you're using the second interface for internet already, there must be a default route pointing to the direction already. The question is "Is it always the primary default route like with higher priority (lower number)?"

It's up to how you implemented two default routes to split/load-balance traffic toward the internet.
