Access Denied Error when on Xfinity Wifi
Hopefully others see this outside of just Xfinity.
I have been getting Access Denied errors on various websites when I go through my Xfinity Gateway. When I run through my VPN the error goes away. That's because I am now masked. The same happens on any Android phone in my house that goes through the Xfinity Gateway. When I turn off the wifi and go through my Cell Network everything works fine. I have access to IT specialists at Siemens, plus I myself am EXTREMELY knowledgeable about how internet addresses and security protocols work. I have also spoken with other highly trained IT specialists. In all occasions they have said the problem is with Xfinity, not my PC or my router settings, or my VPN or firewall. It also has nothing to do with my browser, cookies, cache, etc. Nor is the problem that my IP is blacklisted, as you can go online and find that out with a simple mouse click.
The only way I can work effectively on my PC is through my VPN. Some sites recognize VPN's and thus I get blocked. In those situations it must be turned off, and fortunately that is few and far between. However, sites like United.com, Southwest.com (which I have two accounts for my frequent travel requirements) get blocked. I can't check-in, book a flight, log into my accounts, or anything. There are countless other sites as well with the same problem. Fortunately for me I can access United and Southwest through my VPN or with my cell phone using Cellular data and not through my gateway. Xfinfity is aware of this issue and really doesn't care to get it resolved. If you call their help line they will do three things in this specific order. First, reset your modem. Second, send out a tech to change out the modem. Third, blame your system. I find it comical that the third solution somehow proves the issue is my system when everything works fine when not using the Xfinity gateway. I can setup a hotspot anywhere and not have a problem. I can install a non Xfinity modem to solve the problem, only to have it once again return in a few days. The problem is with Xfinity.

It doesn't matter what modem you use. The problem will continue to return. Once you get a new IP address the issue returns usually around day 5, give or take. Fortunately I live in a community that has an agreement with Xfinity which expedites all problems. Our community is large enough for the HOA to have negotiated this within the contract. I am currently at the engineering level of support and they have been unable to locate the issue. What we may do next is create two internet connections and separate gateways. I will put just two PC's on one, and all the other devices on the other. We shall see if there happens to be a device that is causing my IP to get flagged. If both go down then it just continues to provide evidence that the problem is downstream of my router.

"Access Denied / You don't have permission" messages are issued by the destination site, not by Comcast. These typically result when a person or a program (malware?) using your Internet service is doing something target servers don't like. You'll probably need to ask the sites admins for help with this.

I am having the same issue with multiple sites and have been doing some testing ipand found that if I use the xfinitywifi instead of the gatewayI can get to all the blocked sites. I'm going to leave it connected for a few days to the xfinitywifi and see if the issue returns.

When you change from one Xfinity gateway to another, even if both are the same model, your public IP changes. If abusive traffic continues to arrive from the "new" IP, security measures at destination sites will block traffic from it, and the "Access Denied / You don't have permission" messages will resume. Note that Xfinity's gateways don't issue those messages when they block traffic. Those come from the destination sites.
As stated above, something using your Internet service is doing behaving in a way those target servers don't like.

If the phone is using your Xfinity Wifi, a site which has blocked your public IP will block all traffic from it, including traffic from an Android phone. If the phone is switched to cell data it will be assigned a new public IP and traffic will (probably) resume.
Sites maintain their own internal blacklists, and when your public IP is added to one and you try to reach the site, it responds with "Access Denied / You don't have permission" messages.
And again:

I am seriously considering buying my own modem and router to replace the Xfinity device given that the XB7 I have does not allow users to release/request a new IP address. Having my own modem would at least allow me to clone the MAC address from one of my dozens of devices, which should generate a new IP address when rebooted. Fugly workaround but it might be the easiest.

This discussion has been enlightening, but I'm not sure it addresses my related problem, which is:
Accessing my Comcast email addresses. On my laptop (MacOS 14.5) I can access all my email accounts via Apple Mail (gmail, iCloud, ATT), except NOT my Comcast addresses. They are blocked and the message is "Online Status - Temporarily blacklisted IP Address - try again later."
Oddly, I can access those and all email addresses via my iPad and my iPhone (all using the same local LAN as my laptop), but NOT via my laptop which is using the same LAN wirelessly.
xfinity blames Apple (and the user) but I think it is more than that based on this discussion. Any ideas? Thx.

Final update. It appears the escalation department finally got Engineering to work with Akamai to resolve the issue. I am no longer receiving access denied errors on any of the Akamai websites. Let's hope nothing changes.
