Endpoint Protection

I am having trouble using the email feature of Shadow Protect on a client. I know that my SMTP Email server is working and the server responds to the Shadow Protect email test by connecting, but the response from the SMTP is lost. I'm pretty sure the port is getting blocked by my firewall on the client.

How do I create a firewall exception for this client if it is managed?

Is it possible to make this exception specific for this client.

Thanks

Do you want to create an exception for the port or the application.?

Go the firewall policy and create a new policy and there you can define the exception that you want to create

Not sure what ports need to be opened I will try first with the application.

I do not see how to manage exceptions on the client. I assume this needs to be added on the Management Console at the server?

The Symantec Endpoint Protection includes a default Firewall policy with default firewall rules and default firewall settings for the office environment. The office environment is normally under the protection of corporate firewalls, boundary packet filters, or antivirus servers. Therefore, it is normally more secure than most home environments, where limited boundary protection is available.

When you install the console for the first time, it adds a default Firewall policy to each group automatically.

Every time you add a new location, the console copies a Firewall policy to the default location automatically. If the default protection is not appropriate, you can customize the Firewall policy for each location, such as for a home site or customer site. If you do not want the default Firewall policy, you can edit it or replace it with another shared policy.

Table: How to create a firewall policy describes the tasks that you can perform to configure a new firewall policy. You must add a firewall policy first, but thereafter, the remaining tasks are optional and you can complete them in any order.

Hello,

What makes you think that Symantec Endpoint Protection's Network Threat Protection (Firewall) is blocking the ports or the application??

Do you have the SEP client installed with  Network Threat Protection (Firewall) on the same server??

If yes, Could check the Traffic Logs / Packet Logs from the Symantec Endpoint Protection Client, if there is any ports being blocked??

This could be done by: 

Opening SEP client> View Logs > Click on View Logs Button; Next to Network Threat Protection and Traffic Logs / Packet Logs

If there is nothing being blocked, then it would be Windows Firewall, Try disabling the same and check if the issue is getting resolved.

Hope that helps!!

Acronis B&R email works without a problem on this machine

I can send emails to the Network without a problem from this machine

Windows Telnet Client can send emails from this machine

>>Opening SEP client> View Logs > Click on View Logs  

SEP client Traffic logs show that traffic is getting blocked, but Packet logs show no blocks

Hello,

In the future, please link to relevant documents rather than copy and pasting them here. It is too much text and decreases the readibility of the thread.

Hello JerryF,

If you want to create a firewall rule which affects only this one managed client, you have two options.

1. Put this client in a unique group in the SEPM and then apply your customized firewall policy to only this group.
2. Add a customized firewall rule to the client itself (as opposed to adding the rule to the policy in the SEPM.)

I am going to assume you will want option 2 and will provide instructions for that. If you need something different, let me know. I am also going to assume you are using SEP 11.0.x (as opposed to SEP 12.1), since you were not specific.

By default, a managed SEP client will not allow a user to create their own firewall policies from within the SEP client GUI. You will need to change the client interface control settings from within the SEPM to give yourself permission to to modify the client-side firewall rules. Follow these steps:

1. Login to the SEPM
2. Click Clients
3. Select the group that your client is in
4. Click Policies (the tab at the top)
5. Remove policy inheritance (checkbox at top) if necessary
6. Expand Location-specific Settings
7. Click Server Control (it will open a new dialog box)
8. Select Client control from the list
9. Click OK
10. Wait for the SEP client to pick up the policy change. (You can speed this up by right-clicking the SEP system tray icon on the client and clicking Update Policy.)

After you have made this change, you can now modify the client-side firewall rules using the following steps.

1. Double-click the SEP system tray icon
2. Click Options next to Network Threat Protection
3. Click Configure Firewall Rules...
4. Click Add
5. Fill out the rule information as you see fit and click OK.

I suggest creating an Allow All rule (which, as the name suggests, allows all network traffic in or out of the box) and bumping it to the top of the rule list in order to confirm that this fixes the problem. If an allow all rule does NOT fix the problem, then any more specific rule (i.e., restricted to a certain port, protocol, or application) most certainly won't fix it either. Thus, testing the allow all rules can save you some time in the end.

Regards,

James

Would not do that in future. Thanks
