    Yes, I can ping... Something... :)

    Thanks, yes I can see IPv6 pings reaching the system running the BinkD server so traffic is getting to the machine concerned... just not it seems to the port via IPv6

    If you think the problem is in UFW, you can turn it off for a while. I think the problem is not there.

    Yep turned it off and problem remains :(

    I think your problem is somehere in your router PI, you should open ports 24554-24555 there as well. But as I'm no linux expert, I dont think I
    can help much more.

    So look at the Raspberry Pi that acts as the end point of the tunnel?

    The main router connected to the internet does have 24554-24555 open already, and IPv4 traffic coming in via my ISP works OK

    Your tunnel is working ok as you can poll out by ipv6.

    True

    His tunnel is working, he can make outbound connections. So the protocal 41 is open to the tunnel endpoint computer. (PI).

    I can also ping the Debian box via the Pi endpoint tunnel using IPv6... so I figure things must almost be working as I can reach the system from the internet via IPv6 and the tunnel using ping

    Hello Paul,

    Tuesday October 12 2021 10:38, I wrote to you:

    So far so good.

    But your binkp server is still not reachable via IPv6. I have one more suggestion. Reread the Fidonews articles I wrote with the title "A second life for the Linksys". I document how to set up a tunnel, route a /64 to the LAN and open ports on an OpenWrt router.

    The setup may be comparable to what you have on your Pi. Maybe if you compare you setting with mine, you will have an "AH Erlebnis".

    For your convenience I have made the articles available here:

    I can also ping the Debian box via the Pi endpoint tunnel using IPv6...
    so I figure things must almost be working as I can reach the system
    from the internet via IPv6 and the tunnel using ping

    Question:
    Is one native IPv6 and the other endpoint a 6-to-4 tunnel? This *may* be an issue. Using IPv4 as a test would help. I know natively on my access node
    I can not ssh to it using it's tunneled IPs because the MTU doesn't match. If
    I use a direct IP connection there's no issues at all... and again the MTU matches at 1500 not 1480 as a tunneled link would. Could this perhaps be
    an issue? Just thinking out loud :)

    At the main router it is needed only to open protocol 41 from he.net to your PI so that the tunnel works. Anything else on the IPV4 side is irrelevant.

    In my Ubuntu:

    tommi@pin:~$ sudo ufw status|grep ipv6
    Anywhere ALLOW 216.66.84.46/ipv6

    No native IPv6 here :( I'm only able to access IPv6 because I run the he.net tunnel on the Raspberry Pi. It in turn assigns other devices on my LAN their IPv6 addresses.

    Before I moved to Linux for my HUB things worked fine on Windows for BinkD. So with the settings in the Edgerouter and the settings in the RPi end point for the IPv6 tunnel unchanged, my hunch is that it's something not right in the Debian 10 box I built that now runs the HUB and BBS

    It's an older Pi, not sure.

    If I can ping to the box that's not enough to know things are OK right? OK will see what I can find.

    I think I figured it out (at last).

    It turns out the Rpi endpoint of my he.net tunnel was missing some FORWARD rules in the ip6tables setting. When I finally dug into that and saw it was missing such a rule for the new static IPv6 I had set for my new Linux box things finally started working.

    If you would like to test

    agency.bbs.nz

    I'm hoping all is well now.

    Ok, so by process of elimination, what happens when you shut off ALL your firewalling? Don't forget you probably have one firewall on your router,
    one on your RPi, and one on your Debian box. Insure they're ALL off... test your bink. Turn the one on your router back on, test bink. Eventually if it
    is firewall related you'll find which one it is.

    I write my own firewall so it's simple for me to maintain it. It almost looks like UFW is almost like manually writing iptables rules. If still no go then look at sysctrl.conf. If that's good then look at your routing. You should
    be able to "traceroute6 bbs.n1uro.com". If you can do all that, then I'd look at your bink settings. If everything looks great, then try IPv4 only. This
    will be a hair pulling experience but you'll get it.

    I'm stuck as to know why I can't seem to get ports open for my IPv6 address when I have UFW seemingly enabled.

    ip6tables -nvL
    ip -6 route show
    ip addr show
    ifconfig

    would be very helpfull info

    if ufw fails, change to shorewall

    But it feels like I'm 90%+ sorted as I know the Debian box can happily poll outbound BinkD traffic without issue.

    ipv4 and ipv6 is 2 firewall rule set imho also in ufw

    one use iptables, and another ip6tables

    Any help appreciated.

    gentoo ? :=)

    Doing this now. Cheers. :)

    It uses deprecated API and may leave the kernel network stack in a really unpredictable state.

    I guess you are using iptables instead of ipchains and ipfwadm. Or... ?

    really unpredictable state.

    Using it for viewing (as Benny suggested) is probably safe?

    I've seen some Linux distros however where `ifconfig` is even not available unless you install some legacy package. Thank God, BSD is still a Unix-like system.
