MMS IPv6 Broken in SFOS 3.0.2.8 Oulanka
 

connman firewall updates (3.0.1 => 3.0.2) broke my IPv6 MMS (T-mobile USA).

i have no idea how to add a specific iptables rule to fix just MMS, so i just undid the big global change in /etc/connman/firewall.conf:
IPv6.INPUT.POLICY = DROP
=>
IPv6.INPUT.POLICY = ACCEPT

p.s.: anyone have a better suggestion for a more specific fix?

Maybe this command could help. I don't know if it is tcp or udp, so maybe you need to modify the command.

EDIT: the port could be 8080 for US you need to try. Ah that would be the outgoing port. I don't know on which port sailfish is listen btw, need to check later (normally SMPP when operating over TCP is 2775).

I am working on a gui (genwall) to also implement this in the future.

My best guess would be DNS setup in the ipv6 rules.
Try to just allow UDP/(TCP perhaps also) for port 53

Yes but then also the browser wouldn't work, or does only mms go with ipv6?

So I couldn't try because I have no small sim with mms function.:(

We need more informations, if you don't have ip6tables command you need to install iptables-ipv6 package.

With active mobile data connection do:
And attach the file please.
You could also check, with lsof command, for connections when you receive a mms.

You could also configure ip6tables to log rejected tcp packages, I would set "--log-level notice". And then you can check with:

the rejected connections.
