Two IPSec with same subnet on their end

L0 Member

I can't find a How-to document or community comment on this exact issue.  Some that are close.  And maybe I didn't search with the right terms.

 

I have one customer that connects to a resource on our network.  We set up an IPsec VPN between them and us.  Their inside subnet is 192.168.1.0/24.  I set up a static route on our 'default' router that moves all 192.168.1.0/24 traffic to 'Tunnel 4' (their tunnel).

 

I'm trying to add a second customer via IPsec VPN, but they have the same inside subnet.  I don't have the ability to tell either of them to create a NAT rule on their ends, so I'm trying to work it all out on my end.

 

I've thought about creating a separate virtual router with a separate public IP and using that as the VPN endpoint for them.  I just wanted to make sure that is the best way to go about this.  Seems I could just create a NAT rule that translates their IP address into something else and then, I could just route traffic to/from that (something else) IP range to 'Tunnel 5' (the new tunnel).

 

Is this something easy that I'm just overlooking?  Am I on the right track with that NAT idea?  Or is the separate router the best option?

 

I appreciate any help and opinions given.
