unstable SSL VPN connection on Mac OS X 10.5.7

Hi,

 

My connection is very unstable. The connection rarely stays up for an hour and reconnect is very hard, I have to try 5-10 times until successful.

 

 

How can I ask my F5 client to log with debug so that I can get better idea what is the problem? I see in the /Library/Internet Plug-Ins/f5_sslvpn.bundle/var/log/ only the err file with single line

 

 

16:03:37 SSLVpn::svpn: error 13

 

 

Is there any possibility to control my client parameters? I mean the ones that control how pppd will be invoked?

 

 

Best Regards,

 

Georgi
