Original Pull Request: https://github.com/netbirdio/netbird/pull/3085

State: closed
Merged: Yes

Describe your changes

Properly format IPv6 addresses found in X-Real-IP headers to avoid errors on the call to net.ResolveTCPAddr. IPv6 addresses need to be formatted [1234::abcd]:443, which is handled automatically by net.JoinHostPort.

Issue ticket number and link

Checklist

Is it a bug fix
Is a typo/documentation fix
Is a feature enhancement
It is a refactor
Created tests that fail without the change (if possible)
Extended the README / documentation, if necessary
