Comcast 6to4 how-to?

[mrhanman]

Easily fixed?

I think it is now, I changed the default gateway address, as well as configuring the interface before trying to configure routing is generally a good idea.

fixed rc.newwanip and function interface_6to4_configure();

@databeestje:

;)

So, just a gitsync, and off to the races?

[databeestje]

yep, no binary changes required

[mrhanman]

OK, I just did a gitsync and nothing seems to have changed.  I then installed the latest snapshot, which was a few hours newer and did another gitsync.  I still have no ipv4 gateway on my PC, and no default ipv6 route on pfSense.

Just to be clear, to do a gitsync, you SSH into the box, hit 12 for pfSense Developer Shell, type 'playback gitsync git://github.com/bsdperimeter/pfsense.git', and hit enter a couple times, right?  I also rebooted a few times, just for fun - both the PC and pfSense.  Did I miss something?

EDIT: Also, there is only the ipv6 gateway listed under Status -> Gateways.  The ipv4 gateway is missing.

EDIT: I tried adding an ipv4 LAN gateway in the GUI, and a strange thing happened.  The original ipv4 LAN gateway reappeared, but I couldn't set it as default, and I couldn't get the new LAN gateway to work.  I just delelted all the ipv6 settings on the interfaces, and everything is back to normal - minus ipv6 support, of course.  Now, I'm going to try to add the settings back.  Maybe it'll work this time around.

EDIT: I'm about to reset to defaults.  Nothing else has worked.

wow, yeah, that sounds horrific, i'm really not sure what has gone wrong but it appears it's thoroughly confused.

The VM I setup for testing has a WAN_DHCP gateway for IPv4 and a WAN_6to4 gateway for ipv6.

Both of those gateways are automatically added by the system during setup. I did start with a clean install of 2.1 which may be the difference.

I had no time to setup a test vm behind it to verify I actually got a v4 gateway on the LAN, but i do see a "routers" line in /var/dhcpd/etc/dhcpd.conf do you have such a line in your dhcpd.conf?

All is working now for me.  Both v4 and v6 gateways and routes came up fine at boot.  Thanks again!

One question.  I'm using IPv6 Prefix ID "none".  Is that the correct configuration or is it better to assign a prefix ID?


[databeestje]

assign something other then "none" and it will get assigned to the LAN interface.

A 6to4 wan has 65535 choices. 0000 to ffff.

[irvingpop]

Strange, after changing the Prefix ID to 1 (chosen arbitrarily) from none,  pfSense could no longer ping the IPv6 gateway (WAN_6TO4)  – even after reboot.  However, everything else worked  (ex.  ping6 ipv6.google.com from both pfsense and machines on LAN).

Changing back to none (and reboot) and the WAN_6TO4 gateway is pingable from pfsense again.

[mrhanman]

I still haven't gotten around to starting over.  :-[  Would a "Reset to factory defaults" be just as good, or will that leave something behind?

EDIT:  Went ahead and did it and - woohoo! - 6to4 is now working as it should.  Must have been all the various versions I've gone through over the last year that messed it up.  I still get that error on line 42 at startup, though.

I think there might be a corrupt PHP file in /usr/local/pkg from a defunct package.

[mrhanman]

Is there anyway I can check for what's causing it and remove it?  If I'm not mistaken, it did this on the first boot, before I had added any packages.

[databeestje]

ls -l /usr/local/pkg see if there is a file there that you don't recognize.
