We have made our linux server loaded with RedHat5, a gateway to the internet.All of the traffic goes through our machine.The default policy in the packet filter is "all deny".We are able to browse every site except the hotmail one because it uses "https" protocol.What do we require to accept packets from this site ? Also it happens only with "" and all those sites which use "https".

you must open port 443 for tcp and udp protocol, check you firewall setting abd add rule for accept packets on this ports, for example for kernel 2.2.x

ipchains -A forward -s 0/0 -d 0/0 443 -p tcp -j ACCEPT
ipchains -A forward -s 0/0 -d 0/0 443 -p udp -j ACCEPT
