It depends on the firewall, but Firewall-1 can do this, sort
of. You have to open up another port (259). One would then
telnet to that and authenticate. It notes your IP address
and checks the rules for what you're allowed to do, and
opens the appropriate ports to the appropriate IP addresses
from your IP address (whatever it might be at the time).
Does that make sense? If other firewalls can do this, I'd
like to know about it.
Hope this helps.
