I am using Ubuntu 9.10 with Arnos IP tables firewall.
I'm unable to find any documentation on /etc/arnos~/firewall.conf
There is a NAT_FORWARD_IP section, but I dunno how to configure it.
So I must use iptables manually.
Code:
iptables -t nat -A POSTROUTING -p tcp --dport 80 -s 192.168.88.9 -j SNAT --to-source 1.2.3.4
The above code doesn't apply when I restart arnos.
The below code works - everything is using the new external IP. However, that is the problem - I need just Exchange using that IP so these stupid tenants with viruses don't blacklist my ******* server.
Code:
iptables -t nat -A POSTROUTING -p tcp -j SNAT --to-source 1.2.3.4
So why can't I just add an -s switch and specify my Exchange server like the first code?
THANKS!!!!
