Hi, i have internet vpn server used for anonymous browsing, but i want to forbid clients to access anything at port 25 (smtp). I tried adding iptable rule [code]iptables -A OUTPUT -p tcp --dport 25 -j DROP[/code] and it does block that from the server but VPN clients still have access on port 25. How to block them?

this is an iptables question, try something like [code]iptables -A FORWARD -p tcp -i tun+ --dport 25 -j DROP[/code]
