New Trusted network can ping existing, but not the other way around
I have a case open with WatchGuard support (Case - 01730594).
My existing network have on interface 1 Trusted 10.0.0.5 /24
I created a new network on interface 5 Trusted 10.0.5.1/24
I'm connecting a cable from interface 5 to laptop, and I'm getting the correct dhcp scope, and I had to add a firewall rule to allow interface 5, 10.0.5.1 to be able to access everything else (DNS serves, AD etc) on interface 1 on the existing network. I'm able to ping anything on interface from this network.
But from the existing interface 1 network, I'm not able to ping the laptop on interface 5. I can only ping interface 5 gateway, 10.0.5.1
Then I connect a cable from interface 5 to a Netgear managed switch port 1.
Port 1 is untagged with 1,5. The management IP of the switch is set static 10.0.0.9 with 10.0.0.5 as the gateway. Same as interface 1, but I'm not able to ping the switch either.
As far as I can tell, I have interface 5 on the firewall carrying 1,5 untagged traffic, and interface 1 on the switch to receive 1,5 untagged traffic.
