[CLUE-Tech] Advice sought: should I use SSH or not?

[ian]

The majority of firewalls leave the high end ports open.  

Test this by setting up sshd to run on a high port.. ie 10005
Then try to ssh through the firewall.  

Although this open high end ports has been changing on some of the stateful
firewalls.
