ATP 700 NAT didnt forward 1:1 443 and 80 ports
Freshman Member
Hi.
ATP 700, 1:1 forwarding to the IP WAN interface on ports 443 and 80 does not work; the ports for the GUI were changed from defaults. The firmware is up to date. Everything is ok with other ports. In the logs ACCESS FORWARD.
Did anyone have this problem?

Yep, i have one WAN ip. Is this a problem? I planned to change subnet WAN from /30 to bigger.
No just checking I test with one WAN IP
your log seem to show a connection to 443 without the NAT happening to port 55443 which is odd

Hello @extsa
I wonder if it is worth you checking that your ATP700 is running the latest firmware?
see https://support.zyxel.eu/hc/en-us/articles/360013941859-Security-Products-Firmware-Overview-and-History-Downloads-for-FLEX-ATP-USG-VPN-ZYWALL#h_01HF42Q862DD5T0Y4E7JYG3756 and the below screenshot.
You might be experiencing a bug that has been fixed, or one that has not been fixed.
Kind regards,
Tony

testing here with:
USG FLEX 200
V5.38(ABUI.0)
port 80 forwards to 55580 fine to a test HTTP server
Do you have one WAN IP?
