A customer is using a Barracuda NGF300 firewall. The clients create a VPN connection using the Barracuda NG VPN client (3.5) on Window 7x64 Professional from their local station to the Firewall appliance.
Some times the time to establish the link is fast (less than 10 seconds) and at times it can take 50 seconds to establish the connection.
Can anyone suggest why there is such a time variance? This happens when users are remote and the variance takes place from the same remote location (e.g. the owner's home).
Are there any tools someone could recommend that would help identify what is causing such a variance in establishing VPN connection?
