I'm lookng for help with a IPSEC tunnel that i need to make. I have a client that needs us to provide him an Pubic IP address that we can then nat to our internal host IP. We normally use only one Public IP that we give out for our clients to create our IPSEC tunnels, but we have a client who needs to connect to us from his Cisco ASA 5510 and he needs us to provide him with a Public IP. I can't nat our original IP as it will break all my other existing IPSEC tunnels. I have another Public IP I can use but I am uncertain how make this work.
I am attaching my normal VPN IPSEC tunnel which utilizes our primary public IP. If you can help, please contact me back and perhaps i can explain my goal in better detail.
