[Serusers] outbound proxy tables

Hello to all I have SER configured as a multihomed outbound proxy, like in this page: http://www.voip-info.org/wiki/index.php?page=SER+example+outboundproxy In this configuration, SER puts users in diferent tables: if (dst_ip == 192.168.0.1) { if (!save("location_internal")) { (...) Does someone have these tables? The page says "For this example to work, you must also follow the nathelper module instructions for creating new location_internal and location_external tables. Be careful to use underscores ("_") and not hyphens ("-") when creating the new tables." But I cant find these tables .... Does someone have them??? Thanks Joao
