I'm having some port forwarding issues issues with iptables.
We are using iptables as a firewall with 2 nics and on ip alias.
I'm trying to port forward on the alias ip
eth0 = 65.x.x.1
eth0:1 = 65.x.x.2
eth1 = 192.168.x.x
I'm wanting to forward certain ports(80,5071...etc) that makes request on
eth0:1 IP 65.x.x.2 to forward to internal IP 192.168.x.x. I have setup the
following rules but I must be doing something wrong.
iptables -t nat -A PREROUTING -p tcp -i eth0 -d 65.x.x.2 --dport 80 -j
DNAT --to-destination 192.168.x.x:80
iptables -t nat -A PREROUTING -p tcp -i eth0 -d 65.x.x.2 --dport 5071 -j
DNAT --to-destination 192.168.x.x:5071
iptables -A FORWARD -p tcp -i eth0 -d 192.168.x.x --dport 80 -j ACCEPT
iptables -A FORWARD -p tcp -i eth0 -d 192.168.x.x --dport 5071 -j ACCEPT
Any help would be greatly appreciated.
Thanks
