how do i block domain with iptables
can i know how do i go about doing this with iptables?
web proxy server
Clients within example.com should have access
clients outside of example.com should not have access
configure pop3 server
clients within myl33t.org should not have access to your pop3 service
can i put the domain name in iptables or should it be ip address? and if its ip address how do i find out whats the ip address? do a ping test?
ip address not a good solution
In general IPs change, you want to use a secure authentication schema with stong user/passwd combos, and/or hardware one-time keys like YubiKeys or with a VPN.
