   Hello Tommi,   
      
   Monday October 11 2021 20:29, I wrote to you:   
      
    MV> That outgoing IPv6 works does not automatically imply that it is open   
    MV> for unsollicited incoming protocol 41 packets.   
      
   This is what I wrote 10 years ago in my Fidonews article titled "A second life   
   for the linksys Part 1"   
      
   === quote ===   
      
   If you get this result your tunnel is working. To enable incoming   
   pings however you need to open the firewall for protocol 41. Protocol   
   41 is the protocol used for 6in4 tunneling. The firewall of openwrt is   
   closed for all unsollicited incoming packets by default. Bij pinging   
   out over IPv6, the firewall is opened for protocol 41, and it can be   
   pinged from outside, but it closes again after a minute or two. Add   
   the following lines to /etc/config/firewall to keep the tunnel open   
   permanently:   
      
   [code]   
      
   # Accept proto 41 so it always reaches the tunnel endpoint   
      
   config  rule   
           option  src     wan   
           option  proto   41   
           option  target  ACCEPT   
   [/code]   
      
      
   === end quote ===   
      
      
      
   Cheers, Michiel
