Problem Description

Location Awareness does not pick up the Juniper VPN adapter and therefore does not change to the settings defined for this location.  

On the Mac OS X, the VPN client software may not use standard names or mark the VPN adapter as “Virtual”.





 ProxyClient allows users / administrators to maintain a “VPN WHITELIST” so that ProxyClient can identify a given adapter as a VPN adapter. This information is useful for ProxyClient to identify VPN locations.


“VPN whitelist” is a comma separated list of interface names. It is present in the following location: 


The above com.bluecoat.proxyclient.plist must be updated with the correct information.

1: Determine the name of the Juniper Virtual Adapter using ifconfig.

$ ifconfig


lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384

 inet6 ::1 prefixlen 128 

 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1 

 inet netmask 0xff000000 

gif0: flags=8010<POINTOPOINT,MULTICAST> mtu 1280

stf0: flags=0<> mtu 1280


 ether e8:06:88:dc:7c:20 

 inet6 fe80::ea06:88ff:fedc:7c20%en0 prefixlen 64 scopeid 0x4 

 inet netmask 0xfffffe00 broadcast

 media: autoselect (100baseTX <full-duplex,flow-control>)

 status: active


 ether 90:27:e4:fb:f4:03 

 media: autoselect (<unknown type>)

 status: inactive

jnc0: flags=80d1<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST> mtu 1406  <<<<<<<<<<<<<<<<<<<<<< 

 inet --> netmask 0xfffffe00


2: Add the name (jnc0 in this case) to the proxyclient.plist file in /Library/Preferences

Defaults write /Library/Preferences/com.bluecoat.proxyclient  "VPN Whitelist"  "jnc0"


 The proxyclient.plist file will look like this:  

(defaults read /Library/Preferences/com.bluecoat.proxyclient 


    AutoUpdateProhibited = 0;

    BypassedLSPs = "";

    CacheDirectory = "/Library/Caches/Blue Coat ProxyClient";

    CrashDump = "";

    EnableDebugTrace = 0;

    InstallDir = "/opt/.bluecoatsystems/proxyclient/bin/";

    KeepBackupInstallLog = 0;

    Key = <>;

    LastCMConnection = 1;

    MsiPath = "";

    MsiVersion = "";

    NoUiShortcut = 0;

    ProxySettingsType = "";

    SupportFolder = "/Library/Application Support/Blue Coat Systems/proxyclient/support";

    "VPN Whitelist" = jnc;

    Version = "";


Once complete, restart the machine or the ProxyClient service for the changes to take effect.
