Block all Internet Access execpt 443?

[mchipser]

Is there a way to block all internet access via GPO? or maybe IPSEC? (I know ipsec does ip:port but all?) I would like to block all access except 443 access.. maybe a whitelist?

Windows XP Pro (Standalone no DC)

Use The TCP/IP Filtering it will do the job.

Start -> Control Panel -> Network Connections -> Your Network connection -> left click -> Properties -> Select "Internet Protocol (TCP/IP)" -> click Properties -> Click Advanced Button -> Options Tab -> TCP/IP filtering -> Click Properties Button -> Tick Enable TCP/IP Filtering -> Permit Only TCP Add Port 443 -> Then Reboot
