The router doesn't get the IP it's the modem that gets the IP. The router is
connected to the modem and uses the public IP/Internet facing IP that has
been assigned to the modem by the ISP.

The "posting host - you're the one that's making the post back to the
server". It is one of your machines that has the client NG reader running on
it that's using the public facing IP that has been assigned to your modem to
make the post. You can switch all you want to different NNTP servers. There
is only one IP that's being used by your router that has been provided to
your modem by your ISP that's allowing communications with the ISP's network
for a machine that has a direct connection of a machine to the modem or a
router connected to the modem with machines connected to the router, with,
all the machines connected to your router using that one public facing IP
assigned by the ISP to your modem.

Again, it's your public facing IP assigned to your modem that's used by your
router and your machines using the router are connected to the router, that
is the posting host IP back to the ISP's network.
If you don't know how that NAT router is working, then here is some info.
