Re: bidirectional vpn

just wondering if you are referring to a lan-lan vpn, which can be established from either sites. one requirement for this scenario is that both sites have to have a static ip.

Re: bidirectional vpn

yes..its lan to lan vpn...actually the existing vpn is already there and it was a hub and spoke. There are 2 spokes and evrything is working fine but only in the direction from spokes to hub.

Now that we hav a public ip on one of the spokes, our objective now is to do bidirectional VPN on this hub to the spoke.

Any sample configuration of this kind if you have will be very much appreciated.
