[squid-users] SSL/SSH/SFTP/FTPS to alternate ports

[Timothy Spear]

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
