Hi,
it works, but is not save since you can not be 100% that dst_uri
presence is strictly related to NAT traversal. It's also used by RR
module to force routing after loose_route; and by dispatcher for the
same reasons.....
if you do not call other function that alter the r-uri except
lookup(location) as I said, I do not see why is not 100% sure that the
user is behind the nat. When loose_route() is used, lookup(location)
should not be used, I see no good reason. dispatcher is for load
balancing and it is usually in front of registrar. In this
circumstances, I would say that the situations to have many settings of
dst_uri is very less probable.

I see here two ways of approaching this issue:
- to have per-branch flags also before transaction creation; will
be a new param to append_branch (8 in total :-/), but this flags will
not be accessible from script; only in branch route;
- use something else than flags for NAT marking (something already
present in all branch stages): nathelper, when builds the received URI
(which will become dst_uri) will append a "nat=yes" parameter; this
parameter will be easyly identify in branch route and NAT traversal
may be activated....
any comments or new options are welcomed.......

Just a thought... is it possible to ingore the nat flag and just
rely on the existence of dst_uri to indicate a NATed UA?

Ho Bodgan!
To use branch routes for branch-only NAT traversal also the
nathelper
and mediaproxy functions must be adopted to work in branch routes.
