Hi guys 1 I try to hide my gameserver IP behind another VPS with an IP-IP tunnel. Everything it's set up but still have a issue. I don't know why but with this IP tables configuration I cannot play game because after first packet, each player it's sent to (Gameserver internal IP). I cannot figure why with POSTROUTING commented below all ports give connection time out like there they fly. - exposed IP address from tunnel - Gameserver IP - internal IP of

Hope someone will manage this for me. Best regards, Florin. iptables -P INPUT ACCEPT iptables -P OUTPUT ACCEPT iptables -P FORWARD ACCEPT

iptables -F
iptables -F -t nat
iptables -X
iptables -X -t nat

iptables -t nat -A PREROUTING -d -p tcp --dport 30001:30011 -j DNAT --to-destination
iptables -A FORWARD -d -p tcp --dport 30001:30011 -m state --state ESTABLISH -j ACCEPT
