I have a case where my Network Provider gave me two subnets that are non routable and can only be used on my Edge router (in my case it’s a Peplink device), and my private networks are routed. the network diagram I included would describe it better.
so in order to establish a PepVPN tunnel I should use a routable IP (from the 172.16.x.x networks), In my case the IP is in my private network. I need something like Loopback interface in Cisco to use it for my tunnel.
if I added an additional IP on the WAN interface is there a way so I can use it for the PepVPN?
any better suggestions maybe?
