NAT problem or firewall rules?

[jorgevisentini]

Hello, I installed a clean version of 17.1.4 and then upgraded to version 17.1.8 and for some reason my internal network does not browse, even allowing ALL traffic to the internet.

I do not know if it's a NAT issue or if the rules are not being applied correctly.

Hello, I do not know how to delete the topic but as information, the problem was in WAN interface configuration. Even if I select the gateway, it did not save the configuration, I had to edit the interface configuration and add the gateway again. From that moment the connectivity between LAN and WAN worked perfectly.

Interesting that even though the gateway was not set up on the WAN interface, I could navigate from within the firewall to the internet.

Well ... sorry for the inconvenience.
