How to forward a port through squid?

Question

linux

The bottom line is this:
the Internet goes through a proxy that has authorization, everything goes through port 8080.
You need to get rid of this authorization by installing a gateway. Those. end users do not have to configure anything at all - plug in the wire and you are on the Internet.
There is a computer with two setevukha and Debian on board - it will be a gateway.
HDCP is configured on the local network, the external Internet is obtained by static.
Installed and configured squid according to this instruction:
Instruction on Habré
authorization is done like this:

cache_peer DOMAINIP parent 8080 0 no-query no-digest default login=LOGIN:PASSWORD
never_direct allow all

Everything works as it should, only the problem with https remains. Forwarding as in the instructions does not suit me, because the external proxy does not give ssl through 443 but gives through 8080.
How to solve this problem?

PS.
Previously, all this was done on Windows using the Traffic Inspector and somehow worked with sin in half.

Answer 1

I filed an opaque proxy, made a wpad.dat file - threw it where it should, it seems to work.

Answer 2

you need to wrap the ssl port to your proxy, something like this:
iptables -t nat -A PREROUTING -i $LAN -p tcp --dport 443 -j DNAT --to $IP:3128
iptables -t nat -A PREROUTING -i $WAN -p tcp --dport 443 -j REDIRECT --to-port 3128
