Port forward not working ( Solved )

[yeraycito]

Setup opnsense 21.1 - 21.1.2 - 21.1.3 - 21.1.4:

Firewall - Settings - Advanced: default options

 - Reflection for port forwards: enabled

 - Reflection for 1:1: enabled

 - Automatic outbound NAT for Reflection: enabled

Firewall - Nat- Port Forward:

 - Inteface: wan

 - Destination: ANY      Destination port range: ANY

 - Redirect target IP: XXXXX          Redirect target port: xxx

 - Filter rule association: Add associated filter rule      ( default opcion )

Result: All good

Clean installation of opnsense 21.1 updated to 21.1.5:

Firewall - Settings - Advanced: default options

 - Reflection for port forwards: disabled

 - Reflection for 1:1: disabled ?

 - Automatic outbound NAT for Reflection: disabled ??

Firewall - Nat- Port Forward:

 - Inteface: wan

 - Destination: ANY      Destination port range: ANY

 - Redirect target IP: XXXXX          Redirect target port: xxx

 - Filter rule association: None ?

Result: not working

If we put Filter rule association: Add associated filter rule: not working

If active Reflection for port forwards - Reflection for 1:1 - Automatic outbound NAT for Reflection + Filter rule association: Add associated filter rule  : not working

??

Problem solved. The problem was in Firewall - Aliases

I had created a configuration in Aliases to allow a number of ips limited to access the server ( Cloudflare ips ):

 In opnsense 21.1.4 they were configured under the Host(s) option. In opnsense 21.1.5 setting those ips with the Host(s) option gave an error. So I changed the configuration to URLs (IPs). That's why it didn't work. I changed the configuration from Aliases to Host(s) and this time it let me save the changes. From then on everything worked.

Final configuration:

Firewall - Settings - Advanced:

- Reflection for port forwards: enabled

 - Reflection for 1:1: enabled

 - Automatic outbound NAT for Reflection: enabled

Firewall - Nat- Port Forward:

 - Inteface: wan

 - Destination: ANY      Destination port range: ANY

 - Redirect target IP: XXXXX          Redirect target port: xxx

 - Filter rule association: Add associated filter rule
