The Allow All rule does not cover all Ethernet protocols, and you may need to specify an Ethernet protocol type in the rule (for example: 0x886f for Load Balancing).
Determine if the desired traffic is not using an IP. Use the steps for Unmanaged and individual clients to test removing the firewall component. Try disabling the firewall locally or via policy. Test to confirm the status of the issue. Click the rule Allow All Test, and then click the up arrow until the rule is at the top of the rules list. This creates the rule at the bottom of the rules list. Click the radio button Allow this traffic. In SEP, on the Status page, click Options (next to Network Threat Protection).

To do this, right-click the SEP icon in the Windows system notification area, and then click Update Policy.
Once you have created the Allow All rule, force the client to download the changed policy from the SEPM. Click the new rule, and then click Move Up until the rule is at the very top of the rules list. Click All types of communication (all protocols and ports, local and remote), and then click Next. 
Click Any computer or site, and then click Next. Click Allow Applications, and then click Next. Click Allow connections, and then click Next. If the group uses a shared policy, choose Create Non-Shared Policy From Copy. Click the Firewall policy for this client group to open it for editing. This action may take several seconds to complete In the Group is still inheriting policies, uncheck Inherit policies and settings from parent group. In the SEPM, click Clients, then select the client group which contains the affected client computer. To move clients, right-click the client, then choose Move. This ensures that the following test does not affect other computers. Most vendors will specify which network ports and protocols their application uses to function so that you can properly configure firewalls.Ĭreate an Allow All rule for managed clients Caution: Before creating the Allow All rule in Symantec Endpoint Protection Manager (SEPM), move the client into a client group by itself, with a non-shared policy. If you do not know the ports and protocols the application uses, consult the application vendor's documentation. You will need to create an additional firewall rule (or modify an existing rule) to allow the application's network traffic through SEP's firewall. 
If the application works, the original firewall ruleset configuration does not allow network traffic through to the application. Once you have created the Allow All rule, test the network application to confirm that the application works. Leaving an Allow All rule permanently in place significantly reduces the computer's security posture. WARNING: Creating the Allow All rule is a troubleshooting step only, and is not a resolution to this issue. If the application issue is resolved by adding this rule, reconfigure the SEP firewall to allow the network traffic. Create an Allow All rule for unmanaged clients.Create an Allow All rule for managed clients.
To determine whether the SEP firewall blocks network traffic, create a rule that allows all network traffic through the firewall, then test the rule.
