How can I disable the Stateful Firewall Feature during the installation of the Cisco VPN Client?
A. For VPN Client versions prior to 5.0: Refer to the Documentation Changes section of the VPN Client Rel 4.7 Release Notes in order to learn about the two topics “Using MSI to Install the Windows VPN Client without Stateful Firewall” and “Using InstallShield to Install the Windows VPN client without Stateful Firewall”. For VPN client versions after 5.0: Beginning with Cisco VPN Client release 5.0.3.0560, an MSI installation flag was added to avoid the installation of the guild in firewall files: msiexec.exe /i vpnclient_setup.msi DONTINSTALLFIREWALL=1 Refer to Bypassing Installation of Firewall Files When Stateful Firewall Is Not Required section for more information regarding this.
