iptables

today I able to migrate some of the game servers to another server and needed some help to redirect the traffic from old ip to the new one.

SERVER1 1.1.1.1 ----- (internet ) -----> SERVER 2.2.2.2

I asume to use iptables to perform this, for that used this rule on my centOS box in the server1.

/etc/sysctl.conf: net.ipv4.ip_forward = 1

iptables -t nat -A PREROUTING -p udp --dest 1.1.1.1 --dport 27015 -j DNAT --to-destination 2.2.2.2:27015
iptables -t nat -A POSTROUTING -j MASQUERADE
iptables -t nat -A POSTROUTING -d 2.2.2.2 -p udp --dport 27015 -j SNAT --to 1.1.1.1

But the client cannot connect to the server from the old ip, the redirection don't started.

Hi all, I'm setting up port forwarding for an L2TP VPN connection to the local Windows 2003 VPN server. The router is a simpel Debian machine with iptables. The VPN server works perfect. But I cannot log in from the WAN. I'm missing something. The VPN server is using a pre-shared key (L2TP) and… >>> More

I was thinking initially needing to do a reverse proxy or something so I could get some SSL/TLS traffic look like it is being terminated at a server and IP address in the AWS cloud, and then that traffic is forwarded onto our actual web servers that aren't in the cloud... I've not done much iptables… >>> More
