Nope...it's in open beta, but NAT is *not* technically required on the
OR-U in this case.
I've used the subinterface mechanism quite a few times in 3.8 to
completely renumber a network without the client even knowing about it :)
If we assume that the OR-U has a public IP address and you want to create
a subinterface address of 192.168.200.1, I've done the following:
---------
add subi rfc1918
set subi rfc1918 address 192.168.200.1
set subi rfc1918 netmask 255.255.255.0
set subi rfc1918 port ether0
---------
Now, all the internal machines at 192.168.200.(2-254)=20
will see the OR/U at 192.168.200.1 assuming their gateway/netmask
is set up properly. Using static routes, I can pass packets from this
network all the way to my "border" router which speaks non-beta NAT=20
(maybe a Cisco or Ascend?) *OR* I can put NAT on the PM3 (upstream
to the OR-U) and translate the packets from there.
The release notes for ComOS 3.9 suggest that I can configure NAT on
the OR/U to do this, but quite honestly in several attempts I've
never gotten it to work *unless* I use a numbered PPP/Frame connection=20
to the PM3 (i.e. I cannot have a public network and a private NAT'd
network on the same interface).=20

Numeric stability is probably not all that important when you're
