[Serusers] could not rev. resolve IP......

Hi!This my openser.cfg;I've 2 asteriskathome with openser installed;I want to copy the authentificated sip registration from one box to another and have always the same Sip registered in all 2 box, so if one box falls down the other can run without reinitialized all the sips (like Phoner..cubix...and also IP phones...)....I'm using vrrpd...12 is the master, 11 is the slave, 200 is the virtual IP(this point to the master in the first case..and all Sip proxies like the phoner or cubix points to the master..(I can set only 1 proxy.. 192.168.251.200 ..in x-lite I can set more proxies and I'vent problems..)(for this I must use openser..)
