I've got Ubuntu and Squid running on a machine acting as a transparent proxy and a default gateway for many pc's on my network, which means all internet bound activity comes through the interface to be filtered before leaving for the router (192.168.1.1). HTTPS/SSL (443) does not work because packets on port 443 will come in and hit a wall as I have no rules specified for it.
How do I use iptables to create a passthrough for 443 connections?
----------------- EDIT -----------------------
Managed to get https working after setting the proxy settings for SSL to point to the squid box. However, if I were making a linux router (which I sort of am), would it mean SSL would never work unless I have a proxy running? The IP address for the linux box is 192.168.1.235 and i've set a test computer running winXP to that as its default gateway. Surely there's a way to allow 443 SSL to "pass through" without even touching on the proxy?
I'm also a tad confused as to why https is working at all...I haven't got any sort of routes or anything in the iptables that deal with 443. Any light shed on this would be greatly appreciated!
