Why not use proxycommand and nc to connect to lan hosts:

You would use something like this on your external .ssh/config

Code:
host proxy_server
user therk1
hostname your.domain.com
port 22
host lan1
proxycommand ssh -q proxy_server nc lan1
host lan2
proxycommand ssh -q proxy_server nc lan2

You can then just ssh to proxy_server,lan1 and lan2 hosts from the command line

SSH-ASKPASS-FULLSCREEN(1)				      General Commands Manual					 SSH-ASKPASS-FULLSCREEN(1)

NAME
ssh-askpass-fullscreen - A simple replacement for ssh-askpass written with gtk2 SYNOPSIS
ssh-askpass-fullscreen DESCRIPTION
This manual page was written for the Debian distribution because the original program does not have a manual page. gnome-ssh-askpass is a GNOME-based passphrase dialog for use with OpenSSH. It is intended to be called by the ssh-add(1) program and not invoked directly. It allows ssh-add(1) to obtain a passphrase from a user, even if not connected to a terminal (assuming that an X display is available). This happens auto-matically in the case where ssh-add is invoked from one's ~/.xsession or as one of the GNOME startup pro- grams, for example. In order to be called automatically by ssh-add, ssh-askpass-fullscreen should be installed as /usr/bin/ssh-askpass ssh-askpass-fullscreen is a program that... ENVIRONMENT VARIABLES
The following environment variables are recognized: GNOME_SSH_ASKPASS_GRAB_SERVER Causes gnome-ssh-askpass to grab the X server before asking for a passphrase. GNOME_SSH_ASKPASS_GRAB_POINTER Causes gnome-ssh-askpass to grab the mouse pointer will be grabbed too. These may have some benefit to security if you don't trust your X server. Keyboard is always grabbed. SEE ALSO ssh-add(1), ssh-askpass(1). AUTHOR
This manual page was written by Marco Presi (Zufus) <zufus@debian.org>, for the Debian GNU/Linux system (but may be used by others) and it is based on that for x11-ssh-askpass by Philip Hands and the one for gnome-ssh-askpass by Colin Watson <cjwatson@debian.org> May 8 , 2004 SSH-ASKPASS-FULLSCREEN(1)
