Ipsec Gre using one physical interface

[mag2suban]

IOS XE 3.10 with just one physical interface being used ...all hosts in public range and when they need to reach some other network ..they need to  be able  trigger a IPSEC GRE tunnel through that one physical imterface thats on the same network as the hosts

Any pointers ...appreciated !

You have not given us much to work with here. Some description of the environment would be helpful. What hosts are you talking about?

My first guess might be that something like DMVPN might be what you are looking for. It allows remotes to connect to the hub and then to dynamically build IPSec GRE connections to other remotes in the DMVPN network.
