DISCLAIMER: I'm not a network expert and don't play one on TV either.
As far as I know, the NAT translation table that does the work is the one in my
Linux box. That is where the incoming packets get translated into the internal
IP addresses/ports and the outgoing packets get translated into the single
external IP address.
All that the Actiontec box will see is [external IP] <-- NAT --> [Linux box]
Since the Linux box has only one address on this interface how does the
Actiontec NAT table get filled up? Is there some subtle aspect of transmitting
a stream of NAT'ed packets between the Actiontec and the Linux box that I'm
missing here?
I run VOIP with Verizon and we have 4 computers in use as well as two MagicJack
(VOIP) devices.
Are we just lucky so far?
Thanks,
Eric
