Hardware Version: V1

Firmware Version: 1.3.1 Build 20250220 Rel.67749

Hello,

I've tried multiple times to add/create a static portforwarding via the controller GUI. When adding a first and new rule this always fails as the gui claims the destination ip is invalid.

I can confirm the address is a valid and active host ip within the default lan subnet.

Settings -> Transmission -> NAT -> Portforwarding.

In my case two WAN uplinks (WAN3(main) & WAN4(backup) are available and active.

Rules tried:

name: test

status:enable

source ip:any

interface:wan3 (also tried any)

DMZ: not checked (tried also DMZ but same error)

Source port: 22 (tried also others)

Destination ip: 192.168.1.17 -> Active and valid host within my lan subnet (tried also a bunch of other ips but the error keeps being the same "invalid ip")

Destination port: 22 (tried also others)

Protocol: All (default value)

This seems like a bug. Is this one already known and under development for fix ?

Hi @bdv01

Thanks for posting in our business forum.

Not aware of any similar cases recently.

Some you might consider:

1. Different browser. Could be a cache or a browser issue.

2. Reset the whole system and see if this persists.

If that persists, it could be a firmware problem. I assume it is 1.
