Ports Blocked on IPV6?

i know ports are blocked on ipv4 but are any blocked on ipv6 residential?

how about any limitations allow incoming and outgoing traffic?

Edit: more info on my setup

modem: netgear cm700

router: tplink axe95 (it does block incoming traffic on ipv6.i assume it is my router,i may try another router if it has ipv6 on it and see what happens.i did try directly to modem but could not access it outside network)

device to access outside network Libre SBC based off of rpi 3b+

software: nextcloud with apache2

i need to access storage outside my network to view or add files when needed.id rather use things i already have and to learn more than have a subscription to something though might be my only option.

my biggest issue is accessing outside my network.i can access my device within network but jave to use ip address on other devices though i am trying to get access into my network before working on amything else.

i know a little about debian/raspbian.i can install and purge things basically with a few other little changes.

i have tried variations of a reverse proxy, noip for my dns and openvpn.certain software like wireguard causes issues to the point i have to reinstall my os and start over.i dis have someone offer to access my device and take a look but installing the software needed also did not work.

i have been reading up and learning on the network aide of things but as im sure you can see, it is my downfall and i do not know enough.

apologies if i do not reply to your comment.ended up getting a little busy and have a hard time getting on long enough to reply.that is why i added some updates.

thanks all.

Ports are the same for IPv4 and IPv6. A port is like the door to your house. A boy goes in front door or a girl goes in front door. The front door remains the same.

It would make sense that the same ports blocked for IPv4 would be blocked for IPv6. It's about blocking specific traffic. Why would it matter where the traffic is going? Can't find documentation other than people saying as much on Reddit though. Also, do you mean blocked by Cox's network or blocked by the Panoramic gateway? I have heard of the firewall in the Panoramic gateway causing problems with inbound IPv6 traffic. However, if you are concerned about inbound traffic and IPv6, you probably should be using your own router.
What is the overall problem or what are you trying to do? What is your network made of and how is it configured?

  apologies.i should have mentioned i am using my own modem and router.
  i thought the same when it came to ports being blocked on both ipv4 and ipv6.i did chat with an agent and though they said they do not block ports on ipv6.they did not seem to be entirely certain.
  i am working on accessing a device on my network so i can view/add files.
  i have a separate modem and router with my devices connected to them through wifi and ethernet.i do use dns and openvpn but still not able to access my device outside my home network.
  i am also talking to the router company about ipv6 ports blocked for incoming traffic.i know there is no option to edit ipv6 firewall and is by default enabled. i am trying to rule out what could possibly stop access outside my network.

    Apologies for any confusion. The restricted ports are the same. https://www.cox.com/residential/support/internet-ports-blocked-or-restricted-by-cox.html This link talks more about ipv4 vs ipv6; https://www.cox.com/residential/support/ip-version-6.html

I’m still trying to figure out how I can get into my Gateway settings. I put in that ip address on line and the cox gateway page comes up where you put in your username and password but I never created one ? How could I get in it?

  ::edit:: I thought you were OP. Why are you posting here when your question has nothing to do with OP?
  If you have a Panoramic gateway, the default username is admin and the default password is password. If that doesn't work, you or someone else must have changed it. If so, you either need to figure out what you/they changed it to or factory reset the gateway. How you factory reset depends on which gateway you have. What model? See here for different kinds.

Took me a while to figure out why the forum was saying there was a new post when there wasn't any new comments. Turns out that is what happens when OP edits OP.
As for router, ouch. TP-link. Not only might they be banned in the US because they possible phone home to China(where they are made) but they hide some of their features behind the paywall for their Homeshield product. Most of the advanced settings require the app which requires a TP-link account. I don't see any way to customize the firewall at all, never mind a IPv6 firewall. Maybe something in Homeshield?
So not only is this not a Cox issue, but I think you are lacking the right hardware and understanding. I was hoping it was going to be something simple you are overlooking, but that doesn't seem the case. I suggest posting this question on Reddit. On either Cox's sub or r/Homenetworking. Since it's not Cox related and not within scope(and I don't really have any good ideas) I won't be able to help, but maybe someone else here can. Good luck.
::edit:: 1 thing I do want to mention again is to test things direct to the CM700 modem to rule out any ISP issues.
::edit 2:: If/when you replace the router, you may want to replace the modem too. Most/all Cox infrastructure is DOCSIS 3.1 compatible, and even if you don't sign up for the faster speed, a D3.1 modem would give you more consistent speed and possibly higher upload speeds. It might also help with latency issues because D3.1 added latency improvements and the CM700(and ALL 32x8 D3.0 modems) were known for a latency bug relating to the Puma CPU inside.
