IPv6 tunnel settings

Hello there, this is my first post to this forum and my first day using Comodo. I have the following question:
I try to establish a tunnel using IPv6, but it won’t run while running Comodo (or Windows firewall). The tunnel is created with BT Exact IPv6 Tunnel Broker Service; it’s purpose is to connect to a Usenet provider.
I know the required settings for Zonealarm (below), but could not translate it to Comodo settings.

Rank: leave it (mostly 1) Name: IPv6 Protocol State: Enabled Action: Allow Track: None

Below that is 4 fields with “any”
Protocol op modify → add protocol → add protocol

Protocol: custom
Description: IPv6
Name: Other
Protocol Number: 41

For the Dutch speaking, the procedure is from
this forum.
