- After installing Elements Agent (EPP for Computers or for Servers), VPN connection stopped working and is blocked by the firewall feature.
- How to create a custom Elements Endpoint Protection profile to allow the VPN connection?
- Which ports need to be opened to allow PPTP, L2TP and IPSec VPN connection through the firewall?
In this case you have to start by creating a custom profile which can be edited.
Creating a custom profile:
After creating a custom profile, you can start creating new firewall rules.
- Log in to the Endpoint Protection Portal
- Go to the Profiles page
- Select the circular symbol with three dots in the middle next to the profile you want to clone
- Press on clone profile
- Enter a name and label of the new custom profile
Creating a new VPN firewall rule:
The ports and protocols that need to be allowed vary between each VPN connection type. Verify with your VPN provider the type of VPN connection you are using.
- Select the profile you want to use
- Select Firewall
- Go to Firewall rules and select add rule
- Enter a name and description of the rule, e.g Allow VPN
To allow common PPTP VPN traffic:
To allow common IPSec VPN traffic:
- Allow PPTP tunnel maintenance traffic, open outbound TCP port 1723
- Allow PPTP tunneled data to pass through router, open outbound protocol 47 (GRE)
If IPSec IKEv2 VPN connection is not working after creating the above firewall rules, enable Allow unknown outbound connections from the profile and see if it helps. By default Windows firewall has unknown outbound connections allowed, while the F-Secure firewall profile will block them.
- Allow Internet Key Exchange (IKE), open UDP port 500 inbound and outbound
- Allow IPSec Network Address Translation (NAT-T), open UDP port 4500 inbound and outbound
- Allow Encapsulation Security Payload protocol (ESP), open protocol 50 inbound and outbound
- Allow Authentication Header protocol (AH), open protocol 51 inbound and outbound
To allow common L2TP VPN traffic:
Once the firewall rules have been created, the profile needs to be assigned to the target devices.
- Allow L2TP traffic, open UDP port 1701 inbound and outbound
- Allow protocol 115 inbound and outbound
Assigning a profile:
- Go to the Devices page
- Choose the device(s) to which you want to assign a profile to
- Click on Assign > Assign profile
- Select the profile with the VPN firewall rules and click Assign
