vpnc & X Apps

["Paul R. Ganci" <ganci@xxxxxxxxxx>]

I am using VPNC to connect to my employer's network of SUN solaris 
systems. I can login into the Sun workstation on my desk at work with no 
problems. However if I try to open an X application on my home system 
from my workstation I keep getting:

Error: Can't open display:  vpn226.myworkdomain.com:0.0

DNS is working properly since vpn226.myworkdomain.com resolves to 
xxx.xxx.xxx.xxx which also happens to be the IP address assigned to 
device tun. The solaris box on my desk is using the csh shell so on my 
workstation I did:

setenv DISPLAY vpn226.myworkdomain.com:0.0

and on my home PC:

xhost xxx.xxx.xxx.xxx

Clearly I am missing something. Do I have to open something up on my 
firewall in addition to the usual VPN ports? I need to be able to open 
some X apps on my home PC for it to be of use. Any help is, of course, 
greatly appreciated. Thanks.
