Alternatively, you could use your first SSH session to tunnel into the second machine. For example:

$ ssh -fgNL 2202:somelan.example.com:22 user@gateway.example.com

$ ssh -Xp 2202 user@localhost

I do a similar thing to access my linux boxes behind a linux firewall at home. In this case ‘defender’ being the firewall and ‘digdug’ the server I want to ssh to, yes yes – 80′s arcade theme for server names. :)

ssh -t defender ssh digdug
xterm &

I have used the ‘-t’ option to do this through 4 servers as well.
