[Serusers] problem with nathelper

Hallo to all, I'm a new user of SER. I live/work in italy. I've downloaded ad installed the latest debian packages of SER find in iptel.org ftp space. The version is: ser_0.8.12_i386.deb I've installed and configured for a basic test with mysql module: ser-mysql-module_0.8.12_i386.deb all went ok :-) I've two Grandstream BudgetTone102 and with 2 pubblic IP all work great. I can register in mysql and I can query for the other ip. The problems came when I tried to configure nathelper for work behind a NAT-machine (a simple linux with iptables). I've tried many howto, also the config find in: http://lists.iptel.org/pipermail/serusers/2004-February/005996.html BUT always I've this error... # /usr/sbin/ser -c 0(916) set_mod_param_regex: parameter <ping_nated_only> not found in module <nathelper> 0(916) parse error (97,43-44): Can't set module parameter 0(916) parse error (110,22-23): unknown command, missing loadmodule? 0(916) parse error (232,46-47): unknown command, missing loadmodule? ERROR: bad config file (3 errors) someone can explain me what's wrong? thanks. -- Gianni Olivieri | Debian/GNU Linux gianni(a)gnuthink.org | Linux registered user #333000 (8) It is more complicated than you think. <RFC 1925 - Fundamental Truths of Networking>
