OK so the next step is:
Routing over tunnel to the other proxy and on it(which has ssl-bump)
If you have a public on the remote proxies which can use ssl-bump then route
the traffic to there using Policy Based routing.
You can selectively route by source or destination IP addresses.
Now my main question is: Can't you just install 3.5 on the 3.1.23 machine
and bump there?
Some of the content will not be blocked since 3.1.X cannot intercept SSL.
Depends on the situation you would be able to block all traffic expect ports
53, 443 and 80 and see what happens.
How are you intercepting the connections? What are the iptables rules you
What OS are you running on top of the Squid boxes?

yes I have full control of all three proxies, both local proxies and
remote proxy; and in my LAN I use static IP addresses;
cache_peer_access remote-proxy allow remote-domains <-- this is
neccessary because a few domains
have geo location restrictions which are bypassed with this
cache_peer_access remote-proxy allow tv-device <-- but this sends
anything from the TV there,
even requests that should be blocked ...
(selective doesn't work)
the proxy that is used by the clients is a squid 3.1.23, the one that is
remote is a 3.4.14 and the local parent proxy is a 3.5.20
