How to forward a site past squid in iptables?

Question

iptables

Hey!
Before, I let separate computers into the Internet past squid.
Forwarded ports.
And then the task arose, so that the computers went to the site gmail.com past squid.
The fact is that all HTTPS sites go through squid, and gmail.com does not want to!
So I want to forward it past the proxy. How to do it?

Answer 1

More or less like this:

iptables -t nat -N to_squid
iptables -t nat -A PREROUTING -p tcp --dport 80 -j to_squid
for a in $(host -t a gmail.com | awk '/has address/ {print $4;}'); do
    iptables -t nat -A to_squid -j return
done
iptables -t nat -A to_squid --redirect --to-port 3128
