[c-nsp] pix vpn problem

It's likely a problem with the NAT box, sometimes called "VPN Passthrough".
Some of them cannot track/control more than one session.  Netgear is one of
the few that clearly documents this:

Subject: [c-nsp] pix vpn problem

Hello,

A customer has a Cisco Pix (6.3) with remote users using
the cisco vpn client.  When they have two remote people
behind the same NAT box (which we don't control, perhaps
in a hotel) then only one of them can be connected at a
time.  When the second tries to connect, the first gets
disconnected.

Is this likely to be a problem with the (unknown) NAT box,
or on the PIX?  If on the PIX, is it fixable?

Thanks,
-mark
