How does the client know that it shall go through nat?










0















I have a concrete client service that needs to send soap requests to a concrete server service. Concrete in this context means that the ip addresses are static. The requests must go through a “forward” proxy because it needs a different IP address. The communication is mTLS.



My idea was to NAT the request through a VM. Is this enough? Mutual TLS will work out of the box because it only passes the payload through?



Do I change the routing table to define the next hop in the client service or how does he know whom to talk to?



What about Squid? Many use a combination of NAT and Squid and I do not really understand why. Caching, filtering, Layer 7 filter-abilities?
