Is it possible to set up a static mapping that would do that? I.e.:
======
20-A01 NAT...
Static Map 01
Valid=Yes
Dst Port #=69
Protocol=UDP
Loc Port #=69
Loc Address=(the IP address of the ISP's DNS server)
======
I know that you can set up a static mapping like that to be able to telnet
in to the router from the outside but I have never tried doing a "local
address" in reverse.
