There is no http_port line with a name "src" or name "10.99.0.0/24". So those values are meaningless / useless. They may also be confusing you about what the ACL matches. The 31xx values (first) value entry in each ACL will match > forwarded_for delete Not great. "forwarded_for transparent" is better. But this is pointless anyway since your request_header_access "All deny all" line below will delete the X-Forwarded-For and Forwarded headers anyway. > http_access allow ipv4-1 > http_access allow ipv4-2 > http_access allow ipv4-3 > http_access allow ipv4-4 > http_access allow ipv4-5 > http_access allow ipv4-6 > http_access allow ipv4-7 > http_access allow ipv4-8 > http_access allow ipv4-9 > http_access allow ipv4-10 Due to the mistake mentioned already in the ipv4-* definitions the above access controls are equivalent to a single line: http_access allow all So none of the below http_access lines do anything.

It is a special *_header_access value meaning do this action for *all* headers which do not have their own named entry here in your config file. I suggest it is a good idea to put that line last in the config sequence of request_header_access with a comment to say thats the default action applied to *all* headers not listed above.

Both the squid.conf and the outerface assignments you mention look correct. Perhapse you have NAT changing the outgoing IP on traffic leaving either the machine or the network? If so you need to make sure the 45.* IPs requested by Squid are allowed to bypass that NAT. Or perhapse you are using a Squid older than 3.4? the tcp_outgoing_address selection in older versions had some bugs that could result in what you describe for *some* traffic (though not allways).
