[OpenSIPS-Users] Problem using a shared usrloc table with NAT Ping (OPTIONS) on both opensips instances

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?)
