Hi, There is no special config needed to allow non-standard ports in e2guardian.
In explicit proxy mode non-standard ports will proxied to e2g by the browser and e2g supports non-standard ports. (This is the best solution - works for all platforms)
In transparent mode, if useoriginalip is enabled the extra ports you want to filter can be redirected at firewall level to the appropriate e2g port (normally 8080 for http and 8443 for https). e2g will detect the original destination port and use it.
