Enabling IPv6 on Comcast home network
-
I need to get a land line so that we can still have POTS and an access point that works well in a home setting. Then I can switch to bridge mode.

Huh? You have a phone number you don't want to loose? Just run on cell, like everyone else on the planet under the age of 80 ;)

I also have home phone through that box and bridge mode doesn't affect it. It still works fine.
-
Putting that box into bridge mode doesn't have any effect on the phone line. I have a bundled Internet/TV/phone deal and removing the phone would break the bundle and cost me more.

That is good to know ... my dad is 89 and he uses his POTS line daily.

Well that explains the pots line ;) heheheh
We didn't want to loose the number - not sure why pretty much only get "extended warranty, scam sort of calls" but do like having a house number. So we got little box that plug into the house phone line and not all the normal house phones work over cell.
Just another option if you don't want to bundle phone with your internet.
Saved money that way vs paying the like 50$ a month it was for pots line. Has worked out well - and yeah wife uses house line every day..

That's not the only reason. I long had poor cell coverage in my home. So, until I could use WiFi calling, I really needed a POTS line. That said, however, cell coverage seems to be improving in the past few years.

Or you could of just done voip. Yeah pots is very reliable - but cost is over priced..

This "POTS" is VoIP. I haven't had a twisted pair phone line since around 2008. However, I still just plug a plain telephone into it. In fact, I have 4 phone jacks here. I connect them to the phone outlet on the cable box.
As I mentioned above this box from Rogers includes both Internet and "POTS" phone and dropping the phone service means breaking the bundle, which would result in a price increase. So, I keep it and the phone number I've had for almost 28 years. On the other hand, I've only had my cell phone number for 26.5 years.
BTW, I've worked with an 8 line POTS box from my ISP at a business customer. It was also VoIP over the cable network.
These days, even the phone company is getting out of the twisted pair back to the CO model. If you still have a twisted pair coming in, it doesn't go any further that a box somewhere in the vicinity, where it converts to fibre.
-
Here in the Eastern/Northeastern US, Verizon is actually retiring its copper infrastructure at many of its COs in a number of states, going all fiber. Not all COs have this privilege, unfortunately. But many do.
To be on-topic... in gateway mode, Comcast's rented gateways will provide a /64 to the gateway's LAN, so no prefix delegation to pfSense, IIRC. In bridge mode, or with a proper cable modem, a residential account should be able to get a /60 (16 /64's), a business account should be able to get a /56 (256 /64's), both via DHCPv6-PD. At least that's what they offered when I last had Comcast internet (switched back to Verizon about 18 months ago when they finally got gigabit fiber to my community instead of 30/5 Mbps VDSL).
It should also be noted that some of the early DOCSIS 3.1 modems (like the SB8200 and MB8600) actually offered multiple network ports that could be used with link aggregation to get speed faster than 1 Gbps. Buy a modem, buy an access point (or a router that can be configured as an access point) to put behind pfSense for WiFi, and stop paying Comcast for their gateway.

I have the same device on Rogers and I have it in bridge mode. I get a /56 prefix.

Hi all - this is OP
JKnott was right that I needed to put the cable modem into bridge mode. Also johnpoz was right that doing so has no effect on the POTS line. I did not have to configure the Netgate in any way. The default settings just worked.
I ended up deploying a Zyxel NWA210AX and it was a straight forward process. I would say that the Zyxel is a good match to the Netgate. I can use Firefox to manage both of them locally and that is how I like it.
I ran out of ports on the Netgate so I will need to deploy an additional switch. I should deploy a second access point so I may just get a poe switch. The only thing I am unsure of is if I want to get a managed switch so that I can learn how to allocate my network resources better.

Actually, I said both.
A managed switch is a good idea if you want to bring out multiple LAN interfaces. Just use VLANs to the switch and configure the ports as needed.

Shame on me for missing that

I have a wifi 6 ap now so I will run my MacBook off of that and free up a port. I can also use a poe injector when I position the ap. When the Netgate has no more ports I will buy one with a larger capacity. Its a great buy at any price.

@jknott said in Enabling IPv6 on Comcast home network:
If you're not in bridge mode, you will only be able to get a single /64, which pfsense cannot split among your LAN interfaces.
My delegated prefix is 2601:18d:8b7f:ea70::/64 in both modes. Is that why only one computer can get an ipv6 address at a time?
But did you actually get a prefix that you requested?
Is that a setting on the pfSense or something I need to specify to my ISP when setting up my account?

Huh? You will buy another netgate appliance with more switch ports? What? That is not cost effective thinking at all.
If you need switch ports you buy a switch, you don't buy a bigger router with more ports in it..
You can pick up pretty fancy 24 port poe switch for fraction of the cost of a netgate router with 8 switchports.. The 7100 is $1k

Where are you seeing that? My WAN prefix is completely different from the /56 I get from my ISP. If only one computer is getting an address, there's something really wrong. A single /64 can provide 18.4 billion, billion addresses. I really don't understand how you can be seeing that, unless you're doing something significantly wrong.
Your configuration should be modem > pfsense > LAN, with the modem in bridge mode.

When I sign into my cable modem on the LAN I can go to Gateway > Connection > Status and see my delegated prefix under Local IP Network. I posted a screenshot earlier.
If a /64 prefix can give me plenty of LAN addresses then the next place to look is the router and/or the Linux boxes. If I bypass the router my Linux boxes both get an ipv6 address. However that breaks my multicast dns.
I am fairly certain that the Linux boxes are not configured quite correctly even though I followed the Arch Linux wikis. I have asked for help in the Arch forums but with no response.

With IPv6 and SLAAC, there is nothing to configure. It just works.
