Hi Rhys,

I suppose so, because these are my iptables rules:

iptables -F

iptables -t nat -F

iptables -P INPUT ACCEPT

iptables -P OUTPUT ACCEPT

iptables -P FORWARD ACCEPT

iptables -A INPUT -d 172.16.58.0/24 -m state --state ESTABLISHED,RELATED -j ACCEPT

iptables -A INPUT -d 172.16.58.0/24 -p tcp --dport ssh -j ACCEPT

iptables -A INPUT -d 172.16.58.0/24 -p tcp --dport www -j ACCEPT

iptables -A INPUT -d 172.16.58.0/24 -p tcp --dport pptp -j ACCEPT

iptables -A INPUT -d 172.16.58.0/24 -p tcp --sport domain -j ACCEPT

iptables -A INPUT -d 172.16.58.0/24 -p tcp --dport domain -j ACCEPT

iptables -A INPUT -d 172.16.58.0/24 -p udp --sport domain -j ACCEPT

iptables -A INPUT -d 172.16.58.0/24 -p udp --dport domain -j ACCEPT

iptables -A INPUT -d 172.16.58.0/24 -p gre -j ACCEPT

iptables -A INPUT -d 172.16.58.0/24 -p icmp -j ACCEPT

iptables -A INPUT -d 172.16.58.0/24 -j DROP

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

service iptables save

Firstly, do you think I planned the network organisation well? Do you have other suggestion (best practices) with 2 interfaces?

Hi Pasquale,

Did you modify your security group rules to allow ICMP and/or 22:tcp access?

Many thanks
Rhys
