Can you tell us more about the firewall and rules for the squid routing? <br />
In my situation, I have shorewall forcing traffic through squid. The easiest way to apply what you want, would be to edit this rule in shorewall, telling to still force all connections through squid EXCEPT the ip number if cs.zixmail.com .

I don't have any rules in my firewall now except to use the web proxy which is a simple check box and then telling it the ip address of the squid server. &nbsp;could you give me an example of what you have in shorewall? &nbsp;sounds like that may work... &nbsp;thanks.

I need to allow unfiltered access thru my proxy for Zixgateway encryption software to work correctly. &nbsp;I just installed squid 2.7 on my windows 2008 R2 server and I am getting the following error from Zixgateway appliance. &nbsp;I am using Sonicwall NSA 220 as my firewall.<br />
<br />
Check for PROXY to wwss.zixmail.com<br />
&nbsp;Check for PROXY to rmail.zixmail.com<br />
&nbsp;cs.zixmail.com is good<br />
<br />
<br />
Any ideas? &nbsp;Thanks.

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.

Software Firewalls

Operating system security (OS security) is the process of ensuring OS integrity, confidentiality and availability. OS security refers to specified steps or measures used to protect the OS from threats, viruses, worms, malware or remote hacker intrusions. OS security encompasses all preventive-control techniques, which safeguard any computer assets capable of being stolen, edited or deleted if OS security is compromised, including authentication, passwords and threats to systems and programs.

OS Security

Encryption is the process of encoding messages or information in such a way that only authorized parties can read it. In an encryption scheme, the intended communication information or message, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients, but not to unauthorized interceptors.
