T-Mobile IP's Blocked
Having a lot of issues with T-Mobile Home Internet IP’s getting blocked by sites and services. Other than using a VPN, which is a pain in the backside + slows the connection + still runs in to block issues, whats a solution? Guessing only solution is to cancel and go back to cable???
I’m slowly finding myself blocked from sites due to T-Mo’s ip’s being blacklisted. First, it was Wikipedia. Couldn’t edit some pages. Then I found my OWN WEBSERVER was blocking me. Used a VPN, got in to my server firewall, and found that ip block lists being loaded by CSF Firewall from major security firms (Such as Barracuda to name one) are doing blanket blocks on T-Mobile IP’s. Games blocking my kids from connecting on their ipads and laptops, even got some weird warning from netflix. Now today, my wife tried to access a site she uses for work, and nothing loads, fire up vpn, sure enough works again. Contacted the site, IP’s blocked. Kids chromebooks occasionally have issues as well connecting to school systems. Doesn’t appear school is blocking all tmobile IP’s though. It seems our ip changes every couple days, so some days it works some days it doesn’t.
This is getting frustrating.
Motorpsycho, I am in agreement with you. Based on comments about bad IPs on a list, I think TM needs to have a lookup table updated regularly with those IPs and when they then dynamically update our own IPs, they should cross check that table and not use any of them.
At least, if I was in charge, that is an approach I would discuss with my team.
Or we could just blame your robot vacuum 🤣
I had T Mobile trade out my modem and the issues went away for about 2 days. Then the blocking message returned (but only on one forum) and the connection drop offs started again. I’m giving T Mobile one last chance to swap out the modem/router and fix this, then I’m taking my business elsewhere.
I’m unaware of a robot being on my network (except for my robot vacuum) and I don’t make many key strokes per minute. All services except that one forum have no issue with my connection. But we do notice the internet connection running verrrrrrry slow on some days (perhaps we are in a fringe area?)
If TM’s IP addresses are dynamic, will this problem rectify itself when the IP changes?

You have been blocked.
Why? Something about the behaviour of the browser has caught our attention.
There are various possible explanations for this:- You are browsing and clicking at a speed much faster than expected of a human being.
- Something is preventing JavaScript from working on your computer.
- There is a robot on the same network (IP 172.x.x.77) as you.
I’m getting that same screen from Blocklist. they suggest disabling outgoing messages from Port 25 on the router. Anyone know how to do that? As you noted, I only began getting that message when I switched to T-Mobile home internet.
I’m having similar issues, especially with Google-related services, ever since switching to T-Mobile Home Internet. Just about every time I do a search, I have to click a Captcha or use my phone’s data instead of the Wi-fi. Sending an email from a non-Google account to a Gmail account gets blocked for originating from a malicious IP.
It seems the most efficient way for a customer to report this would be through Chat or Email Support, but I can only find info for Phone Support (ugh).
tmobile has a serious blacklist issue….and their support is clueless. I tried asking if they could refresh and issue a new ip address. I might as well asked them to perform brain surgery.
Has anyone contacted T-Mobile about this issue? I have had problems getting to the login page for DirecTV. I know it’s being blocked. The page that pulls up says DirecTV is having an issue with my connection.
Both T-Mobile and DirecTV tech support blame each other. I have been referred back and forth between the two and I am starting to feel like a tennis ball.
I have done testing on my own and found if I use my cellphone’s broadband instead of wifi to the gateway, I can log in. If I use a VPN, I can log in.bocaboy2591 wrote:
First, the 403 error is being generated by the Forum website which constantly gets overloaded, hence the error message. Wait just a few minutes and it will clear.
Second, T-Mobile does not block websites. It does lack NAT and and the ability to manipulate DHCP, but that doesn't have any affect on websites.
Have you checked your DNS settings? I'm not sure if you're on a PC or Mac, but either way, make sure the router is listed as 192.168.12.1 and if that’s true, then try adding Google’s DNS, 8.8.8.8. Make sure your VPN is disconnected. Also, is the inability to connect common to all devices or just the one you're writing about?
Thanks for clarification on the 403. It’s maddening using these forums, glad I copied my other messages before submitting, as it took a good 15 tires before the site would connect.
Next, I did not say T-Mobile blocks websites, I said Websites/servers are blocking t-mobile ip ranges.
I do use cloud flare dns. it works spectacularly. though has Nothing to do with the problem.
Problem is all devices going over home internet. See my response to copz so I can avoid repeating.

Interesting, I did not have any issues access the T-Mobile website. I wonder if you are behind a firewall. I do not use a VPN so I cannot comment on it. If your own web server is blocking you (HTTP), then you have something going on. Is your web server on Linux? If so, Linux runs firewall software that requires adjustments (I used to run Apache). You should revisit your topology and see if have a software layer causing your problems. Of, turn off everything but your PC/Mac client and your T-mobile gateway, then test Internet access.
Good luck!
Bocaboy said it’s the forum getting overloaded for that, so appearantly tmobile is not blocking it’s own ips. just a overloaded forum for that.
I was fairly clear, the firewall is pulling block lists (this is common practice) from security companies (as I mentioned for example, Barracuda, which is a fairly large one). These block lists contain huge swaths of Tmobile IP ranges. None of the blocking is happening from my side. Once I manually remove the tmobile ip ranges from my servers firewall, all is normal again. I will repeat again, these are block lists distributed by web security companies. The lists are for sites/server admin’s to block known problem ip’s and ranges. It just so happens that huge swaths of T-Mobile IP’s are labeled as High Risk. Seems to affect home internet ip’s, does not appear to affect Ip’s on the phone end of things to as great a degree, however, I am seeing our phone’s ip’s hit those lists too.
Doesn’t matter if it’s PC or phone when it goes over the home internet. Doesn’t matter if it’s directly through the T-mobile router or my own asus.
I still have our old extremely slow cable internet (grandfathered plan dirt cheap from the Time Warner days) that I held on to while seeing if I would be keeping Tmobile home internet. A simple switch of the ethernet cable from t-mobile to spectrum modem and back to zero issues.First, the 403 error is being generated by the Forum website which constantly gets overloaded, hence the error message.
