EPNS not working with wildcard web filter


Marten

Recommended Posts

Hello,

Sorry if this is the wrong place to ask, I'm a bit lost on the entire topic, I've tried multiple different ways already. We have two domain computers that cannot get access to EPNS servers. These two computers are the only ones that are in these firewall policies.

Essentially, initially we had a seperate firewall policy that allowed these two computers to access *.eset.com and everything worked flawlessly.

Recently though, we made the change to create a webfilter that blocks access to everything except some work related websites and *.eset.com but through this I constantly get the error for EPNS servers being unreachable.

Any advice? Let me know if I need to clarify something

I assume you mean EPNS (ESET Push Notification Service): https://help.eset.com/protect_admin/10.1/en-US/epns.html

Please refer to https://support.eset.com/en/kb332 for a list of ports and addresses that need to be allowed on a firewall in order for ESET's features to work properly.

Last but not least please provide logs collected with ESET Log Collector so that I can check if you have correct ESET's firewall rules and to rule out the possibility that they got corrupted.

Yes, my bad. I got two things mixed.

From what I see you only need 8883 and 443 ports allowed for EPNS. I have both of them allowed between ESET Protect server and the two computers mentioned.

Just to make it clear, by "firewall" and "webfilter" you are referring to a 3rd party perimeter firewall and webfilter? Not to the ESET firewall and Web access protection that supports URL blocking?

Please carry on as follows:

  1. Enable advanced logging under Help and support -> Technical support
  2. Reboot the machine
  3. Reproduce the issue
  4. Stop logging
  5. Collect logs with ESET Log Collector and upload the generated archive here.
