WAN Failover Gateway

[Bishop527]

Hello All,
I was wondering if a member could assist me on an issue that I'm having, My network - LAN, VLan 10 & 20 and I've setup my gateway group, but when I go into my LAN interface to change It to the new gateway group my Vlans immediately lose connection an I'm no longer able to ping my Vlans from my local LAN network.

Thanks in advance.

Did you turn the only one allow-any-to-any rule into a policy routing rule?
If so, this will force any traffic to the stated gateway.

You have to ensure that the policy routing rule is only applied to upstream traffic.
To do this, you can add an additional pass rule for internal destinations only to the top of the rule set.
