Thanks.
It's a real problem!
If a company have employee using my SER server to make calls to the PSTN via my gateway,
and they want to be able to make internall call too, all their calls will go via my
rtpproxy ?
for the moment no, the limitation is in nathelper, not in rtpproxy. you
can add a small function in nathelper that test if the src_ip on request
is the same with the one in RURI ( after you did lookup("location") in
script); be sure that both caller and callee are nated.

No idea on how configure ser to prevent this ?

Hi,
nat_uac_test can be call with parameter :
"1" : via adress is compared to signaling IP
"2" : test if RFC1918 adress
But in some configuration, i see "3". What is it for ? I can't find it in
the nathelper code.
3 means to do both tests.
Another question, what happen if two people on the
SAME LOCAL network try to call each other via my SER server ?
Their adress will be detected as private and rtpproxy will be use, but it's not needed
as they are visible for each other.
How could i prevent this ?
for the moment you cannot. maybe in the next release will be available a
function that tells you if both nated users (callee and caller) are
behind the same NAT.
Thanks
