Sun Dec 15 00:16:34 UTC 2019

hi Amos,

thank you for getting back to me about this :)

this is my new config

#
#SSL
http_port 3128 ssl-bump \
cert=/usr/local/squid/etc/ssl_cert/myCA.pem \
generate-host-certificates=on dynamic_cert_mem_cache_size=4MB
sslcrtd_program /usr/local/squid/libexec/security_file_certgen -s
/var/lib/ssl_db -M 4MB
acl step1 at_step SslBump1
ssl_bump peek step1
ssl_bump bump all

#Windows Updates
acl windowsupdate dstdomain "/usr/local/squid/etc/wu.txt"
acl CONNECT method CONNECT
acl wuCONNECT dstdomain "/usr/local/squid/etc/wu.txt"
http_access allow CONNECT wuCONNECT
http_access allow windowsupdate

# Recommended minimum configuration:
#

# Example rule allowing access from your local networks.

# should be allowed

# Recommended minimum Access Permission configuration:

# Deny CONNECT to other than secure SSL ports
http_access deny CONNECT !SSL_ports

# Only allow cachemgr access from localhost
http_access allow localhost manager
http_access deny manager

# We strongly recommend the following be uncommented to protect innocent
# web applications running on the proxy server who think the only
# one who can access services on "localhost" is a local user
#http_access deny to_localhost

#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#

# Example rule allowing access from your local networks.
# Adapt localnet in the ACL section to list your (internal) IP networks
# from where browsing should be allowed
http_access allow localnet
http_access allow localhost

# Uncomment and adjust the following to add a disk cache directory.
#cache_dir ufs /usr/local/squid/var/cache/squid 100 16 256

# Leave coredumps in the first cache dir
coredump_dir /usr/local/squid/var/cache/squid

#
# Add any of your own refresh_pattern entries above these.
#
refresh_pattern ^ftp: 1440 20% 10080
refresh_pattern ^gopher: 1440 0% 1440
refresh_pattern -i (/cgi-bin/|\?) 0 0% 0
refresh_pattern . 0 20% 4320

the reason why i have added the windows update lines at the beginning is
that the link says so (below)

https://linuxnlenux.wordpress.com/2014/10/14/howto-allow-windows-updates-through-squid/

this is my domain list

and when im looking at the logs real time

ream

squid works fine just as you said on certain apps/programs, so im really
struggling on this one

thanks,
rob
