I've come a little further. Imagine this network setup: PC1 ------ Gateway -----//-----PC2 PC1: 10.0.0.N on a local network PC2: has world-wide IP address, say: x.y.z Then you can do on PC1: ssh -N -f -R 2200:localhost:22 x.y.z which will create an ssh-tunnel from PC1 to PC2 as a background process, and will force PC2 to listen on port 2200, which will be connected to port 22 on PC1. After establishing this tunnel, you can do on PC2: ssh -p 2200 localhost and you connect directly to PC1. In this process, you do not need any login/password on the gateway!! Exchanging public keys of the two PCs, will skip the password checking. You also can add lines in ~/.ssh/config, to shorten the last command. I know in your case, both PCs are on a local network and there are two gateways inbetween. So this is not the final solution to your problem, but it may help you understand what way to go with ssh. I remember you had login/password of one gateway, which certainly may make things easier. I hope all this helps a bit. Rob.
