Yes, live as in the internet routable IP your DSL
provider allocates to you.
Yes, the router should be doing the PPoE effectively
making your modem only act
as a modem rather than the stock modem/router combo it
came configured as.
Bottom line is if the modem is in bridge mode, the
router configured for PPoE,
then the router's WAN port should be getting a live IP
not a private one. This
makes the link between the router and the internet
appear to be direct as if
there was no modem.

I am sure they could with some combination of settings
but why bother when modem
bridge mode removes the issue?

If you still get a private 192.168.x.x address at the
router's WAN port, you are
NOT in bridge mode.
You should really consider DHCP; Further you should
consider a DHCP setup that
reserves IP based on MAC address so that you can
assign the IP you want to a PC
but do not have to do it at the PC itself because the
PC in DHCP mode will still
get the right IP based on the lease.
