USG500H - SSL VPN connection impossible

kaika313

Hello,

I need to set up the SSL VPN through port TCP 10443 but cannot make it work.

This is our configuration:

USG FLEX 500H FLEX V1.31(ABZH.0)

ISP ROUTER 192.168.1.1 (public static IP address, integrated firewall switched off, map forwarding active for some ports including 10443 TCP pointing to firewall, any other mapped port is working properly) —> USG 500 192.168.1.3

I've enabled SSL as shown here

I can see the two SSL polices active but anytime I try to connect (I use OPEN VPN) default DROP rule is triggered. Here's an example:

What am I missing?

Thank you for your help

Hello!

To set up SSL VPN on port TCP 10443 with your USG FLEX 500H, ensure port forwarding is correctly configured on your ISP router to the USG, and that SSL VPN settings and policies are properly set up. Check for any IEP-Direct conflicting firewall rules causing connection drops, and ensure your OpenVPN client is correctly configured. Reviewing logs from both the USG and ISP router can help identify any issues.
