ZYXEL USG FLEX 200 - ENABLE PING BETWEEN LAN 1 AND LAN 2

Hello,

I have a ZYXEL USG FLEX 200 with two LAN :

LAN1 : 172.17.30.0 /24

LAN2 : 172.18.30.0 /24

I can't ping LAN 2 from LAN 1 and LAN 1 from LAN 2, I tried to add Policy Control from LAN 1 to LAN 2 and LAN 2 to LAN 1.

I also add a policy route from LAN 1 to LAN 2 with a SNAT on outgoing-interface.

I tried to put static route.

But the ping stay in "Destination Host Unreachable".

I upgrade my ZYXEL with the last firmware.


Has anyone had this problem before?

Thanks !

Rafaël DAVID

    You don't need static route or a policy route if PC's on each LAN have a gateway to go to

    likely the PC firewall is blocking ICMP or device not allowing it to be pinged
