Hi I am trying to do port forwarding to another machine. It just hangs when I ssh to it. Here are the lines I am using iptables -t nat -A PREROUTING -i eth0 -p tcp -d 192.168.10.106 --dport 41122 -j DNAT --to-destination 192.168.10.186:22 iptables -A FORWARD -d 192.168.10.186 --dport 22 -j ACCEPT echo > 1 /proc/sys/net/ipv4/ip_forward The line to connect is: ssh -p 41122 root@192.168.10.106 and it just times out. I can ssh individually to 192.168.10.106 and to 192.168.10.186 and when I use tcpdump it seems to show that it is looking for the right machines. When I do an nmap from a different machine it shows the port 41122 as filtered not open. What am I doing wrong - I have tried just about everything. Frustratingly yours Simon Moore
