Hello , Does anybody know why the lenght of both ip-address (s and name) in check_via_address function in msg_translator.c source file dose not check first? Actually i think it's better do. For example if via:192.168.122.1 and src:192.168.122.100, the result returned true, as they are not the same! With.Regards. Mojtaba Happy new year --Mojtaba Esfandiari.S
