I was staging a Sophos XG(Software) using an internal network. Everything was working fine. However, when I change the WAN to a 4G modem with static IP and passthrough, I was unable to access the internet from the LAN or other subnet. WAN IP was correct after the changeover, and rebooting the firewall didn't help with the issue. Using the diagnostic, I can ping out from the WAN interface, but not others. Log view shows cannot file rule to match package.
