Title: Allow traffic from IOT to Lan on specific host and port.
Post by: slusk on August 05, 2021, 08:22:07 pm

Hi.
I am trying to get this to work here.. I am new to this :/

I have blocked all the traffic from IOT to the rest of the network but I want one host on IOT to be able to communicate with one host on LAN just for MQTT.

But I cant get it to work.. What have I done wrong?

If you want one host to one host you need a /32 CIDR

I changed to /32 and that worked :)
