Do you have the log for the connection when you can't access? Other than 22 and
443 as you said.
Thanks,

Here is the access log. I should have included it in the original post. This is
accessing a test machine I setup to hit SSH on 22 and 443. I can also hit HTTPS
on multiple other ports.
1413125068.706 87 10.110.98.21 TCP_MISS/503 0 CONNECT XXX.XXXX.com:22 -
HIER_NONE/- -1413125086.496 8061 10.110.98.21 TCP_MISS/200 3657 CONNECT
XXX.XXXX.com:443 - HIER_DIRECT/54.68.15.208 -
Yes, my intent in the rule set is to provide a list of allowed ports and sites.

check out your access log seeing what
it says. Sounds like you are looking for an AFW from squid. The
ports themselves are defined. You need to make sure the other
ports are opened.
Your rule tells squid to block the non-allowed sites to the
non-allowed ports. Still sounds like FW function, but with the
domain feature only.

Hello,
Here is the issue:
I can proxy through Squid just fine to HTTP and HTTPS. I can
also run SSH via Corkscrew to a SSH server running on port 443
and it works fine.
What I cannot do, is access HTTPS or SSH on any other port
except 443. I have lost track of the number of things I have
tried so any help will be appreciated and I feel like I am
missing something simple.
OS: Ubuntu 14.04.1 LTS
Squid: 3.3.8-1ubuntu6.1
Here is my current Squid 3 configuration:
debug_options all,3
# local network we proxy for
acl localnet src 10.110.98.0/24
# what ports can be the desitnation
acl allowedPorts port 21
acl allowedPorts port 22
acl allowedPorts port 2222
acl allowedPorts port 80
acl allowedPorts port 443
acl allowedPorts port 8443
acl CONNECT method CONNECT
# determine the available sites
acl allowedSites dstdomain
"/etc/squid3/allowed-sites.squid"
# now block anything not on the
localnet or ports
http_access deny !localnet
# allow
connect only for approved ports
http_access deny CONNECT !allowedPorts
# now only allow to the specific
sites
http_access allow localnet
allowedSites allowedPorts
http_port 3128
access_log /var/log/squid3/access.log squid
hosts_file
/etc/hosts
Background (just FYI):
I am trying to setup Squid to control network access from a
local subnet to a select number of domains. I do not need to
bump the encrypted traffic and play man in the middle, I just
need to prevent the servers on the local network from accessing
unauthorized networks. Yes, I know I can do this in the
Firewall, but that is IP based and I am dealing with enough
other companies that maintaining the IP list has become a major
pain. Instead I want to use domains, which I can do in Squid.
Thanks,
Tim
