Servers behind 6to4 IPv6 interface

OK, how about a the raw log output (clog /var/log/filter.log) for those connections and also /tmp/rules.debug

That would give us more detail about exactly which interfaces are involved in the background here.

Here are the logs from filter.log.

ok, no rush. databeestje is off on vacation this week so it may be next week before he can look at it, I just figured he'd need the extra detail given the way the last bit you posted looked.

antispoof for fxp2

But in your firewall logs:

May  1 10:28:23 officefw pf:     71.XX.XXX.57 > 70.XX.XXX.125: (hlim 63, next-header TCP (6) payload length: 32) 2002:XXXX:XXXX:13:XXX:XXXX:XXXX:5cf4.55172 > 2002:XXXX:XXXX:d:XXX:XXXX:XXXX:7884.80: Flags [s], cksum 0xd537 (correct), seq 1951051361, win 8192, options [mss 1220,nop,wscale 2,nop,nop,sackOK], length 0
May  1 10:28:26 officefw pf: 00:00:02.987371 rule 1/0(match): block in on fxp0: (tos 0x20, ttl 30, id 64163, offset 0, flags [none], proto IPv6 (41), length 92)

So the rule should be passing proto 41 from 71.XX.XXX.57, but somehow it's getting 192.88.99.1 there.

We don't have a way to make a proto 41 pass rule in the GUI yet, but you could do one of two things:

1\. Add a rule to pass any proto from 71.XX.XXX.57 to your WAN IP.

or 2\. edit /usr/local/www/firewall_rules_edit.php - find the line with this:
[code]$protocols = explode(" ", "TCP UDP TCP/UDP ICMP ESP AH GRE IGMP OSPF any carp pfsync");[/code]
And change it to something like:
[code]$protocols = explode(" ", "TCP UDP TCP/UDP ICMP ESP AH GRE IGMP OSPF any carp pfsync ipv6");[/code]

Then make a rule on WAN to pass that proto from 71.XX.XXX.57 to your WAN IP.

There may be a bug in the auto rules there, but it would have wait wait for databeestje to look at in more detail.[/s]

192.88.99.1 is the ipv6 to ipv4 broker and a rule that comes from the 6to4 config. I am guessing that is to the world or outside of pfSense domain. I will do as you suggest and let you know the outcome. I hope to have real IPv6 soon and I will not have to worry about 6to4 configs.

podilarius

Unfortunately I have had no luck either way. anyone else with 6to4 configuration on 2 sides able to get this working?

We already replicated the issue, we are currently debugging it with a FreeBSD developer.

I finally got all my stuff configured tonight, and had this issue at first but I have been able to make rules that allow my systems to be accessible from the internet. I followed thishttp://doc.pfsense.org/index.php/Using_IPv6_on_2.1_with_a_Tunnel_Broker ipv6 guide to setup my connection with HE and then added a rule like you see below, before putting in the rule I was unable to ping my ipv6 address or connect to anything on my ipv6 address (going outbound was fine). Basically it is a rule for the opt interface i created for the ipv6 that is an allow everything ipv6 with a desitination of my server ipv6 address.

Here is a paste of HE portscan and ping test for my ipv6 ip after i put this rule in.
