[Serusers] lookup_contacts for natted clients returns local ip

Hi, I have the followning natted contact in my location table: mysql> select * from location where uid ='tw(a)sip.touk.pl'.pl'; +--------------------+-------+-----------------------------------------------------------+ | contact | flags | received | +--------------------+-------+-----------------------------------------------------------+ | sip:tw@192.168.7.2 | 1 | sip:80.53.110.142:61066;dstip=192.168.129.74;dstport=5060 | +--------------------+-------+-----------------------------------------------------------+ when I invoke lookup_contacts the ruri has local address 192.168.7.2instead of public one. Is this correct behaviour? Please point me is this should work as I think. Thank You for any help Tomasz
