Thanks very much.

Maybe you can use the nat_keepalive function of the nat_traversal module
instead of automatic keep alive checks?

I just found this bug which turned into a feature request (from 2012)
someone else had exactly the same problem:

https://sourceforge.net/p/opensips/feature-requests/99/


@Bogdan, if for whatever reason the table is being shared by two Opensips
instances (In my case it's not for balancing/failover at all but just for
having the registrations for two servers in one central place for checking
with external scripts/other optimizations...)

Shouldn't each instance check whether it's his client or not before
sending the keepalive/OPTIONS pings? This would fix the problems in
scenarios like mine and i would guess there are a lot of people with the
same problem: but they probably never noticed it, or never will.

Hi,

I experienced something weird: I got two servers sharing the same
location table. (usrloc module)

My problem is: both servers got nathelper ping (OPTIONS) enabled. The
Opensips instance A has it's own clients and instance B also...

Now as the location database/table is being shared by both servers the
NAT Pings from Instance B are also sent for clients which are registered on
instance A.

I did not find any solution to tell Opensips A/B to only ping "their"
registered clients. The force_socket option of nathelper will not solve my
issue as both servers got their own socket/IP.

Is there any workaround for my situation? (Nat ping does not take the
socket/IP of the registered client into account?)


Best Regards
