[SR-Users] Users can't authenticate via external IP

Hello Kamailio guys, I have the following setup Internet -----> REAL STATIC IP -----> Kamailio Virtual IP(10.2.45.101) I have setup everything and when I try to connect to kamailio from the inside I can successfully register. When I try to register to the REAL STATIC IP which is forwarded to 10.2.45.101 I get unauthorized. I have narrowed down the problem to this: auth_check("$fd", "sip", "1") as I said I can authenticate from the internal network but not from the Internet. What do I need to alter ? Side problem... why when using xlog("L_WARN","$Cxx TEST") kamailio fails to start ? seems that my version does not support the colored output... Thank you for your help guys...in advance.
