[Simh] C9.io

opening any port on your firewall/edge router would make your IP open to  
probes tho, and you'd have to be sure the host you expose is secure so  
that other systems on your internal net isn't at risk. I guess you could  
place your host and guest on a separate vlan and place that into the DMZ  
with rules to allow internal to DMZ access to limit exposure.

Also make sure your router/firewall passwords are strong and not  
manageable from the DMZ. Dynamic DNS would mean you don't have to acquire  
a fixed external IP so you can then access via a DNS name rather than IP  
too.

Alternatively, make access via VPN only possibly with some of the above  
and not expose any open ports so you stay as invisible as possible on the  
web side...
