Opnsense 18 logging in problem - either internet or opnsense works

[Unknown1234]

Hello everyone,


I'll simplify my problem as much as possible.
My opnsense LAN IP is: 10.20.20.1
When I try logging using the browser: https://10.20.20.1/
it simply doesn't open with a message "site can't be reached".
However, when I reset my IP addressed using these commands in the terminal:
1)  sudo ipconfig set en0 DHCP
2)  sudo ipconfig set en0 BOOTP
I will no longer have internet access, but the https://10.20.20.1/ works fine.

When I restart my PC the internet works but the https://10.20.20.1/ don't.

I want a solution where the internet and opnsense both works if it helps I'm using a MacBook Pro and when the internet is not working the network settings shows this message: "wifi doesn't have an IP address and cannot connect to the internet".

Thank you in advance!

Do you have another router/modem in your network?

Make sure you have not disabled the administration anti-lockout rule Firewall>Advanced
There should be a LAN Anti-Lockout rule at the top of the NAT rules
Also, try changing the WebGUI port to something like 82. Then use http://10.20.20.1:82
