Trying to allowing connection to a server from the outside world. Port scanners are reporting the ports are not open. Just after confirmation my iptables are correctly set.
eth0 - Private Lan
tun0 - VPN interface
ppp0 - Mobile broadband connection (no firewall restrictions from ISP)
-P INPUT DROP -P FORWARD ACCEPT -P OUTPUT ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -i eth0 -j ACCEPT -A INPUT -i tun0 -j ACCEPT -A INPUT -i ppp0 -p icmp -j ACCEPT -A INPUT -i ppp0 -p udp -m multiport --dports 53,1194 -j ACCEPT -A INPUT -i ppp0 -p tcp -m multiport --dports 25,53,80,143,443,587 -j ACCEPT
Hoping iptables is the culprit otherwise I'm going to have spend a lot more time on working on this server. Appreciate the assistance.
