I would like to set up an IPSec site-to-site tunnel between my company and an external company. (The external company does not support a dial-in mechanism, so I have to use a site-to-site VPN...)
I would like to access a device with address 220.127.116.11 from my network 172.16.0.0/16. I am not that a big expert with site-to-site VPN tunnels, but I guess I have to create a tunnel between 18.104.22.168/32 and 172.16.0.0/16. The configuration of that tunnel must be done on both tunnel endpoints. This has one big drawback: Internal details of my networking structure are revealed to the external company.
Is there a way to create a tunnel WITHOUT giving the peer all the details of my local network?
Does a site-to-site VPN connection make sense in this context? If so, how should they be configured? If not, what would be alternative solutions if I do not want do communicated in an unencrypted way?
Best regards, Tom
