Change IP route for Blacklist

February 12, 2015 The Geek Decoder No Comments Email, Iptables

Add the clean IP to the server.

Edit the firewall to NAT all connections FROM port 25 to use the new IP.

# iptables -t nat -A POSTROUTING -p tcp --dport 25 -j SNAT --to-source NEW.IPA.DDR.ESS
# service iptables save

Ensure that the IP is on eth1
or…

# iptables -t nat -A POSTROUTING -o eth1 -p tcp -j SNAP --dport 25 --to-source 123.45.6.7
