IPTables, Linksys BEFSR41 and PCAnywhere

["A. Clausen" <techlists@alberni.net>]

We are using netfilter to run a broadband wireless network.  For customers
wanting a public IP, we simply forward a public IP to an internal NAT IP.

We have one customer who wants to use PCAnywhere remotely to contact his
machine on the inside.  As usual, I simply forwarded a public IP to the
private IP.  On the private IP they have a Linksys BEFSR41 router.

Basically it looks like this:

public ip ---> Linux netfilter router ---> private ip ---> Linksys
router ---> customer's network

He is insisting that he needs to actually have a public IP, rather than just
having our Linux router forward a public IP to a private.  We have other
customers doing similiar things, one even opening up ports for MS-SQL
server, without a problem, so I'm presuming that this customer is coming
from a position of ignorance.  But before I start digging deeper, I need
confirmation that this Linksys router is not some bizarre piece of hardware.
