Configuring the CYREN Services for use with a Web Proxy
This article describes how to configure a proxy server for the CYREN services with the Protection module in all NoSpamProxy versions from version 9.2 onwards. To do this you have to download the files
- ctipd.conf (additionally available from version 12.x)
- ctwsd.conf (additionally available as of version 13.x)
from the directory “C:\ProgramData\Net at Work Mail Gateway\CYREN\”.
The following section is responsible for this:
# If you connect to the Internet through a proxy server, you
# should uncomment the following parameters and assign appropriate
#ProxyPort = 80
#ProxyServerAddress = myproxy
#ProxyAuth = NoAuth
#ProxyUserName = user@proxy
#ProxyPassword = 1234
#ProxyAccess = 1
If you are using a proxy server without authentication, remove the # character before the lines “ProxyPort”, “ProxyServerAddress”, “ProxyAuth” and “ProxyAccess”. Enter the corresponding port of your proxy server in ” ProxyPort”. Behind the entry “ProxyServerAddress” you configure either the IP address or the FQDN of your proxy server. For “ProxyAuth” leave the entry at “NoAuth”.
If you are using a proxy server with authentication, you must additionally configure the options “ProxyUserName” and “ProxyPassword”. Enter the corresponding logon information for “ProxyUserName” and “ProxyPassword”. Additionally, you must change the value “ProxyAuth” to “Basic”.
After you have saved the file, you must restart the services NoSpamProxy – CYREN Service (ctasd.conf), NoSpamProxy – CYREN IP Reputation Service (ctipd.conf) and NoSpamProxy – CYREN URL Categorization Service (ctwsd.conf) in order for the changes to take effect.
In order for all Cyren services to function properly, unrestricted access to *.ctmail.com must be given. Also a virus scan on these connections must not be done, because the definitions for the Cyren Premium AntiVirus are downloaded there as well!
