Hey Jon,
You can enable debug on your box and review the logs to see what's going on here:
1. From the Linux client, disconnect the FirePass Network Access connection, if connected.
2. Access the command line.
3. Start a root (superuser) session by typing the following command:
su
Note: For some Linux distributions, you may need to type the following command to start a root session:
sudo su
4. When prompted, enter the root password.
Note: If you entered the sudo su command in the previous step, enter your Linux account password instead of the root password.
5. Type the following command to create a file named svpn.conf in the /usr/local/lib/F5Networks/SSLVPN/etc/ directory and enable level 2 debugging:
echo debug=2 > /usr/local/lib/F5Networks/SSLVPN/etc/svpn.conf
6. Connect or reconnect the FirePass Network Access connection.
Debugging information will be written to the following locations:
/usr/local/lib/F5Networks/SSLVPN/var/log/svpn.dbg
/usr/local/lib/F5Networks/SSLVPN/var/log/ppp.dbg
If you still have no joy i would then remove all the client side components:
1. Log into the Linux system command line using an account with root privileges, or using the su command.
Note: For some Linux distributions, you may need to use the sudo su command instead of the su command to start a root session.
2. Change directories to the /usr/local/lib/ directory by typing the following command:
cd /usr/local/lib/
3. Remove the main SSL VPN components by typing the following command:
rm -r F5Networks
Then log back into the FirePass and allow the client software to re-install.
Also, does this happen to all Linux uses in your environment? I've seen that if the option "Present the user with a message box after successfully connecting Network Access client" is enabled in the Network Access resource settings Customization tab AND browser is configured to block pop ups, then SSL VPN connections never start.
Hope this helps. By the way I pulled much of this information from AskF5 (tech.f5.com). Can't recommend this knowledgebase high enough.
Cheers,
