A little help setting up a connection

Derelict

Again, this works in pfSense if the ISP does what it is supposed to be doing, as is evidenced by at least my DHCP6 connection to Cox that pretty much never goes down and countless others.

I would packet capture on WAN for IPv6 for a while (set 100000 packets or something), pull it into Wireshark and see what's there.

I did the packet capture on my wan interface. I have opened the .cap file but there is no ipv6 packets.

When I capture any traffic it returns a lot of stuff.

Derelict

How long did you let it run for? I would edit/save WAN (no changes necessary) while capturing. I would only capture on address family IPv6.

@derelict

For some minutes..5 or so.

I will do this edit/save wan now.

FWIW, my upstream (Cox) sends an RA every 4 seconds or so.

I don't know where can I see this info.

My wireshark capture now have some things related to ipv6

Derelict

Yeah. See those router solicitations in the second screen shot that aren't being responded to?

There's your problem. pfSense is asking, they're not responding.

You can limit the capture to protocol ICMPv6 to eliminate a lot of that noise too.

@derelict

So in this case I really need to contact my isp to change the cable modem right?

Derelict

All pfSense can do is send the Router Solicitations and listen for Router Advertisements, so, yes. I don't see how anyone other than the ISP can help here.

Note that the last screen shot is full of Neighbor Solicitations which is more like the equivalent of ARP in IPv4.

@derelict

Thank you for helping me. I will contact isp and see what they can do for me.

Trendkill99

I have contacted them and they suggested me to change my cable modem.

Derelict

Hmm. Did they make a recommendation? I use a Netgear CM600 here. Pretty much the only thing I don't like is how tall it is.

Trendkill99

@derelict

No, they use to change these equipments according to availability. At this moment they only have Humax and Arris (that I already have).

Derelict

"Can I get one that works with IPv6?"

Trendkill99

@derelict

I will ask for the humax model. I have a friend using this model without problems.
