IPv6 and captive portal

[maverick_slo]

Hi all!

I enabled captive portal and now my clients can`t get IPv6 address, even after auth.
Is this a known problem?

I have / had the same question.
I guess the default ipfw portal firewall doesn't handle IPV6 DHCP requests yet.
Furthermore, the entire authentication is more or less IPv4 based - so your visitors NEED to get an IPv4 to be able to get out.

Do you have a DHCP IPv6 server activated ? IPv6 Firewall pass rules are present on the portal interface ?
Maybe, after identification on the portal, activated the DHCP client your device and see what happens.

I guess that ipfw will block them…. I never gave it a try.

Portal authentication that is IPv6-ready will be there in the future, but it will need a complete portal code rewrite.

As noted above, there is no IPv6 support in CP. (Also, I don't create any "default" any->any IPv6 rule on CP interfaces, so the traffic will get blocked by pf no matter what ipfw does.)
