If you lost your group password from the Cisco IPSEC VPN but still have the PCF file, you can use this website to decrypt the encrypted password, located in the file. This is useful if you need to manually configure your VPN client (e.g. on a Mac, you cannot import a PCF file with the native VPN client).
To get the encrypted password, open the PCF file with a text editor (such as Notepad), then look for the line starting with enc_GroupPwd=. Copy everything after the = (if you have wordwrap on, make sure you got the entire line), and paste it in the text box on the website, then click the Decode button.
Cisco AnyConnect VPN client may fail on Windows 7 for no apparent reason with the following error:
A possible reason may be that Internet Connection Sharing has been enabled on one or more network interfaces (e.g. used for making a hotspot out of your laptop). Try disabling ICS, then try connecting again.
Add this line to the server config:
push "redirect-gateway def1"
Restarting OpenVPN on the CLI of a pfSense can be done using the following command:
echo "<?php include('openvpn.inc'); openvpn_resync_all();?>" | php -q
This issues a restart command as if you would via the web-interface.
