I need to add some functions in my ser.cfg for nat support. I use my open(ser) as outbound proxy with two interfaces ppp0 and eth0. sip agents send requests to eth0. I want my packets passing through the register and invite blocks by fixing contact with a public ip. All packets from private network must be sent to eth0. Any suggestions Bob Accédez au courrier électronique de La Poste : www.laposte.net ; 3615 LAPOSTENET (0,34€/mn) ; tél : 08 92 68 13 50 (0,34€/mn)
