Thank you Amos and Rafael,
Using the LinuxDnat approach worked great as well.

There are several ways;
1) run Squid on the gateway router for your network, or

Yes, Squid can tunnel non-HTTP data, including TLS data.

First of all, thanks for your attention and time.

I am unable to confirm whether Squid can do what you want or provide

Do you have any recommendations on how I could have it done?
When my tls client tries to reach the target through Squid, using
a "ssl_bump splice", it seems like squid is trying to reach itself

Correct.
how will Squid know what the target is?
In many cases, Squid can learn SNI by peeking at TLS ClientHello,
without terminating TLS. Bugs notwi
Actually with the suggested blind passthrough, Squid would not handle the
TLS termination.
So without a reverse proxy (accel mode), how will Squid know what the
target is?

What do you want Squid to use that SNI for?

If you want simply redirect incoming connections to another IP/port, port
