Comodo Firewall blocks DLNA server

Comodo Internet Security - CIS Firewall Help - CIS
#1

I’d like to know how to configure my comodo firewall (part of comodo internet security 5.12.256249.2599) to allow DLNA servers like XBMC or TV Mobili on my home network. In fact these servers are correctly working if comodo is disabled which is not a good solution for me :wink:
thanks for your help !

Look for the option to “Block fragmented IP packets” (or similar wording) and make sure it is NOT selected.

Sorry, I cannot give step -by-step instructions or more detailed information on where this option is but I no longer have an installation of CIS 5.X anywhere.

Also, ensure that the IP address of your DLNA server is included in any network zones used in global rules.

Hope this helps,

Thanks Ewen !!! You’re a genius ! The IP address of the server was not included in the network global rules.
Everything is now working great.
Thanks again for your help ;D

Hi
Following the panic advices (above), I’ve uninstalled my old Comodo (V5) to reinstal the latest one (v6.3.294583.2937)
This blocks again my TVMobili DLNA server :-[
I’ve verified that the “Block fragmented IP packets” option is NOT checked, but I can’t find how to include the IP address of the server in the network global rules (which solved my problem on the old v5 comodo ). In fact in totaly lost in by the new comodo interface.
So if someone (may be you panic ? :slight_smile: ) cold give me step by step instructions to help me that would be great !

Hello again ;),

The new interface is VERY different to what you are used to, but everything is still in there.

  1. Open the CIS interface
  2. Click the green TASKS link in the top right corner.
  3. Click ADVANCED TASKS
  4. Click ADVANCED SETTINGS
  5. Click SECURITY SETTINGS → FIREWALL
  6. Click NETWORK ZONES and create a zone that includes the IP address of your DLNA server
  7. Click GLOBAL RULES and create a rule to allow traffic to and from the network zone created in step 6.

I think you’ll be right from here.

One hint - At step 2, if you click the COMPACT/ADVANCED toggle in the top left corner, you can then click the FIREWALL heading and jump straight to step 6.

Setting the user interface to ADVANCED mode means that, by clicking the link headings, you can jump straight to the settings for the anti-virus, auto-sandbox, HIPS and the firewall. Neat shortcut, eh?

Hope this helps,
