cable router

[sublime78ska@xxxxxxxxxxx]

I have a customer that has cable internet access, a netgear cable router, and 
an as400.  Can the cable router be configured so that the as400 can be accessed 
with telnet remotely?  (This box is for development only.)  Has anyone done it?

I tried this once before but instead of a cable router the customer had MS 
Proxy server and we couldn't get that to work.  We ultimately bought a firewall 
device.

Thanks in advance for your help.  I hope to not waste too much time trying to 
get something to work that can't work. ;-)
