ip tunnel issue.

I’m trying to do a ip tunnel between two mt boxes each on the net. I had a l2tp tunnel running just fine, but i was having some serious preformance issues with it, vs internet connections so i wanted to try an ip tunnel for preformance.

I set up an ip tunnel interface on each side, set R1 's iptunnel remote address to the ip of R2 and vice versa. and gave them each local, private IPs and the routes to and from.

however my issue is if i ping the remote router, i see data being sent through the ip tunnel, but nothing is being recieved on the other ends IP tunnel.

do i need to seee some kind of connection or authentication?

i followed the manual’s application example for this.

thanks,
