Hi, My this doubt is regarding automatic tunneling. I know that freeBSd doesnot support it. But i feel u can guide me in this. Suppose iam implementing automatic tunneling then is there a need for me to use any of the gif interfaces. I feel that with the present freeBSD architecture i can implement automatic tunneling. My idea is this when ever an ipv6 packet is to be sent over an ipv4 cloud then i should call the gif_output() in the nd6_output(). In the gif_output() i should generate the encapsulation header & call ip_output() to send the packet. The only preoblem for me is to identify that the packet is to be sent over an ipv4 cloud. In the configured tunneling case we have a routing entry & it takes care of calling gif_output(). FreeBSD uses the routing table to find the interface through which the packet is to be sent. In this case if i have to send the packet through an ipv4 cloud then i should specify the interface so that gif_output() is called. Kindly tell is there a way for me to find that the packet is to be tunneled in advance. regards ravi prasad __________________________________________________________________ Get your own FREE, personal Netscape Webmail account today at http://webmail.netscape.com/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
