By following the below instructions you will be able to append customization to the default PAC file served by the Endian UTM Enterprise Appliance

You need to access your Endian UTM Appliance via SSH or serial console to be able to use nano.

You can find some useful command that can be used on Endian's shell (console) here.

Once you are logged in issue the below command:

root@endian:~# nano /var/efw/proxy/proxy.custom.pac

1. Bypass proxy for a destination domain:
   

   if ((dnsDomainIs(host, ".mydomain.com")) || (host == "mydomain.com"))
   {return "DIRECT";}

2. Bypass proxy for a destination IP:

   if (host == "50.50.50.50")
   {return "DIRECT";}

3. Bypass proxy for a destination subnet:
   

   if (isInNet(host, "10.1.1.0", "255.255.255.0")) 
   {return "DIRECT";}

4. Bypass proxy for destination hosts if resolved within an internal IP:

   if (isInNet(dnsResolve(host, "192.168.0.0", "255.255.255.0")))
   {return "DIRECT";}
   

5. Bypassing proxy for a source subnet:

   if (isInNet(myIpAddress(), "10.10.10.0", "255.255.255.0"))
   {return "DIRECT";}
   

6. Bypass proxy for multiple destination domains in one statement:

   if ((dnsDomainIs(host, ".mydomain.com")) ||
   (host == "mydomain.com") ||
   (dnsDomainIs(host, ".example.com")) ||
   (host == "example.com") ||
   (dnsDomainIs(host, "otherdomain.com")) ||
   (host == "otherdomain.com"))
   {return "DIRECT";}

example (bypass windows updates):

if ((host == "download.microsoft.com") ||
(host == "ntservicepack.microsoft.com") ||
(host == "redir.metaservices.microsoft.com") ||
(host == "images.metaservices.microsoft.com") ||
(host == "c.microsoft.com") ||
(host == "productactivation.one.microsoft.com") ||
(host == "sls.microsoft.com") ||
(host == "cdm.microsoft.com") ||
(host == "wustat.windows.com") ||
(host == "windowsupdate.microsoft.com") ||
(dnsDomainIs(host, ".windowsupdate.microsoft.com")) ||
(host == "update.microsoft.com") ||
(dnsDomainIs(host, ".update.microsoft.com")) ||
(dnsDomainIs(host, ".windowsupdate.com")))
{return 'DIRECT';}
