Openser receive registration of both X Lite clients from the same NAT box 193.28.184.10:xxx

It doesn't make sense. The UA uses UDP and send requests from port 193.28.184.13:5060, but it announces address 193.28.184.10:26946 in the Contact header (it means that it's listening in 193.28.184.10:26946), it doesn't make sense.
I assume both are the same network (192.28.184.X), right? then it doesn't make sense at all. How is your scenario between UA and OpenSER?
