If you take a closer look at rules, you = will see something like: > {code:java} > -A PREROUTING -d publicIP/32 -i eth1 -p tcp -m tcp --dport 80 -j DNAT --t= o-destination internalIp:80 > {code} > The problem is that according to this rule only packets coming via eth1(p= ublic interface), will be =E2=80=9Credirected=E2=80=9D to the internal IP. = We need an extra entry to each one of the NAT configurations. For the prese= nted rule, we would need something like: > {code:java} > -A PREROUTING -d publicIP/32 -i eth2 -p tcp -m tcp --dport 80 -j DNAT --t= o-destination internalIp:80 > {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
