maybe I found the problem...
I added the following line after if(has_totag()) {
if(loose_route())... and before the route(1):
xlog("[LOOSE_ROUTE] from $si:$sp method $rm SET_DESTINATION $du");
the $du should be the "rewritten" destination, changed by loose_route.
in opensips log I found:

Oct  6 14:24:35 TDCVIRX09 /usr/local/sbin/opensips[30869]:
[LOOSE_ROUTE] from 94.33.32.xxx:55484 method ACK SET_DESTINATION
sip:77.238.yy.zz:5060;lr;ftag=1a4ab330;did=ed.36ed132

(where 77.238.... is the public ip of opensips), so it seems that
opensips tries to redirect the ACK to itself (a loop?)

how can I avoid this?

thanks
