Aallow Cisco VPN Client through comodo firewall

Deselect the COMODO Internet security firewall driver from the Cisco AnyConnect Secure Mobility Client Connection network adapter.  To do this:

·         From the Control Panel, open the Network and Internet option and then open Network and Sharing Center.

·         From the left-hand menu, open Change adapter settings, right-click on Cisco VPN Client Connection and then select Properties.

·         Now deselect the Comodo driver and click OK.

Following this procedure will allow VPN traffic flow through but it will not offer any protection from the Comodo Firewall. 

Go to the Firewall section, and click the Network Security Policy. Under Application Rules there should be 3 entries related to the Cisco VPN Client:

- ppptool.exe
- vpngui.exe
- cvpnd.exe

Make sure these 3 points to your Cisco folder and make them Trusted. This allows the Cisco VPN Client access through the Firewall and sets up the encrypted tunnels properly (IKE and IPSec).

In the Defense+ section, Computer Security Policy, make sure these 3 files have the same Trusted level:

- vpngui.exe
- ipsecdialer.exe
- cvpnd.exe

You will need the following ports and exceptions set:

Open UDP Port 62515 in your firewall.

Open TCP Port 10000 and UDP 4500 in your firewall.

Add Cisco VPN IPSecDialer and VPNGUI to the firewall exception list. The path to the files are:

C:\Program Files\Cisco Systems\VPN Client\ipsecdialer.exe

C:\Program Files\Cisco Systems\VPN Client\vpngui.exe
