Hello,
I have 1 connection to the Internet(2XX.100.20.10). 1 hub, 1 firewall, 1 box in private network.
The firewall has 3 NIC cards, eth0,eth1,eth2. I can't reach the private network using ssh. I have
ssh running on the firewall on port 1229. Firewall has the NAT rule. Ssh is also running on the
private network box(target). The firewall has port 1229 open and listening(verified).
./iptables -t nat -A PREROUTING -p tcp 1229 -i eth0 -j DNAT -to 192.168.10.100:22
Does anyone know why this would not work? My OS is Ferora Core1, all patched up.
Thank-you!
(Make believe routable IP addresses to protect the innocent)
