This needs a big report. Christos may or may not be aware of it already.

Squid generates URLs for clients to fetch icons etc directly from eth
proxy. Now that we are being strict about what types of traffci work n a
NATO intercept port, it needs a forward-proxy port aconfigured to
receive these requests.

The officially registered port is 3128 so these are fixed by:
   http_port 3128

The Squid listening port number has nothing to do with the port-80/443
clients are sending to and this type of config will cause nasty bugs
if/when the machine runs a proper web server.

Its best to use a random port of your own selection outside the 0-1024
well-known port range. Its only needed between the NAT firewall and
Squid so can (and SHOULD) be firewalled to prevent remote access
directly to it.

Your "pinger" binary is not installed with suid (aka root as owner).

The "--enable-ssl'" directive is obsolete. You can simplify by removing
it. The --with-openssl you have below does the same thing this used to.

NP: its time to stop using that IPv6 directove. Squid works fine nowdays
on a properly configured network. Even if its configured to be IPv4-only.

Not much help sorry. The SSL_Bump fixes available today are almost all
in 3.5.2.
