Trouble with IPv6
« on: August 02, 2017, 04:01:49 PM »
Hey Andy!  I recommended t1n1wall to one of my users for support for his apu, and it is working for him but...  When he enables IPv6, it all goes sideways.  He tried to post but was having trouble signing up.  His thread is here.  http://smallwall.freeforums.net/thread/148/apu2c4  and his problem follows.

-----

So I finally managed, after an arduous process, to get t1n1wall running on the APU2c4. Only one tiny problem so far, besides cosmetics (icon beside DHCP leases to add to reservations is missing, tho the link works). Here's the only major problem today for 2.11.1b140 built on Sat Feb 18 18:30:49 GMT 2017:

Can't enable IP6 - doing so locks up t1n1wall and I have to reset everything via the console and restore saved configuration. I've tried straight from initial configuration with no configurations other than out of box and still no go.

Enable IPv6 support
After enabling IPv6 support, configure IPv6 addresses on your LAN and WAN interfaces, then add IPv6 firewall rules.
Note: you must set an IPv6 address on the LAN interface for the IPv6 support to work.

Of course I had IP6 enabled on SmallWall 1.8.4b11 built on Thu Jun 23 17:11:56 CDT 2016 without problem. Here's t1n1wall 2.11.1b140 built on Sat Feb 18 18:30:49 GMT 2017 status.php - interfaces section:

Would have posted on t1n1wall forum, but registering to post there doesn't seem to be working atm...so here I am. Need to be pointed in the right direction to help diagnose/enable IP6.

Thanks to your previous help I've gotten this far...just about there.

Well I finally figured out a workaround - went to the console after enabling IP6, and disabled pf duh. Attempting to configure for IPv6 (DHCP-D) or (6to4). Something's up, not sure what. Ask for diagnostic additional information and I'll try to trouble shoot, as it seems there's still something amiss...just not sure how to tell for sure, appears to be running...testing further.

I caught up on some bugs recently.  This should be fixed now
