I cannot access my job's VPN from home

However, I can connect to my home OpenVPN server using an OpenVPN client app on my phone. It just took some fiddling with the settings. I suggest you get with your IT folks and have them diagnose the connection IRT.

How were you able to get OpenVPN working to your home server?
That’s all i want to do is to be able to connect to my home network from my phone but with double NAT and no port forwarding, I assumed that was not possible.
Are you using a separate service like “remote.it” or similar to reach your home network?
Can you elaborate on how you are reaching your home server from outside your home?
¡Gracias por tu ayuda!

Would be interested as well.  Still on the older white boxes, but need to be able to remote in and can't because port-forwarding and even DMZ is broken. Tried running OVPN on my Asus to put my whole network on a VPN in an effort to do something about it, but no luck.  Was an automated script from my provider for the OVPN config, perhaps there is something I need to edit in?

Update.  Turns out the event log says I am getting an 809 error.  IT asked me to relay this to TMobile when they respond. Still hopeful. 

Worst case is with the BS that T-mobile is doing with their gateway and internal networking… You could always ask your IT department to provision you on a WVD through Azure (if you have it) or they could setup you up with RDS web browser access.

it’s not t-mobiles fault that ipv4 is out of addresses  ¯\_(ツ)_/¯ 

That is the stupidest comment I've ever read. ipv4 is not out of address and won't be until 2041. ITs a shame that T-Mobile can't do ipv4 when, gee i don't know maybe 90% of the world still uses it. Give me a break.

I think you have this backwords. T-Mobile doesn't want to play nice with vpns. It absolutely weird that they won't support ipv4 when nobody has switched over to ipv6

Oh this is too funny. I just found documentation from T-Mobile stating that "IPv4 is the default internet protocol" Then in Step 6 it stats "IPv6 is an alternate protocol" So then why would they only make their home internet work with IPv6? Too funny!

For those keeping score at home, although I didn't do much testing (wife's employer's VPN), it also doesn't work with GlobalProtect VPN.  I had hoped to switch from Spectrum, but I don't have VPN issues with Cisco AnyConnect or GlobalProtect on Spectrum.  Unfortunately it's looking like the switch is on hold for now.

I'm on the latest firmware and had no issues with AnyConnect. I had issues with OpenVPN and Tunnelblick (3 different servers). I could ping everything and dig but browsers simply don't work.

Based on the previous comment yesterday on the client side (Tunnelblick) I’ve changed MTU down to 1380 (you need to set “mssfix 1420” in the client’s config) and “magically” the problem was gone.

Next day 2 VPNs failed to connect :( Only one out of 3 did work.

Same thing here!!! 😡

SOLVED! After days with my IT department and then with Global Protect in Pali Alto, here's the bottom line. T-Mobile High speed broadband can't handle IPv6 dynamic IPs therefore can't communicate in internet. Global Protect can only handle IPv4.

There are no settings on T-Mobile gate way to make it just use IPv4.
Global Protect doesn’t have a fix/VON software to fix this advanced IPv6 communication 

I can access my company's server for data files, outlook for email etc, but cannot access internet based apps like one login or any websites. Except MSN.com - explain that. Not even Google. Com.

Have to switch to my Verizon cell data hotspot to my company laptop to access internet. Then switch back to T-mobile when done with internet  

T-Mobile is using advanced technology that companies are not ready to handle, and will take them a long time to become compatible.

Since most users don't have IOv6, there's no rush to upgrade corporately. For example, they advise that all the scanner guns in our warehouse aren't compatible with IPv6, so if they upgrade VPNs now, none of the equipment would work in the warehouse.

Nor are VPN providers putting resources into IPv6 compatibility.

im so annoyed that I switched to the T-Mobile high speed broadband new technology that NO ONE at T-Mobile advised this would be an issue. Even calling tech support, they had no idea what the issue would be. After my IT department figured it out I HAD TO CALL BACK T-MOBILE AND BRUNG THEM UP TO SPEED.  Am I in the twilight zone? Ridiculous 

So much for all this infrastructure across the US. If we get this new technology, then can't connect with old technology being used by 99% of corporations, then we're screwed until they decide to upgrade.

How can this be such a mystery in 2021. IPv6 has been in development for more than 10 years.  WHAT's the holdup and lack of warning of the issue.

So annoyed that I switched to this with no heads up. I'm screwed now unless I switch back to my unreliable Cox cable internet that had service outages at least twice a week while I've been working from home.

Mine was just the MTU issue, was able to resolve it by lowering the number. If this blog can be helpful for anyone to troubleshoot and resolve the issue:

Is this a confirmed fix for the GlobalConnect issue?

It connects just fine but the sites I need to access do not load.

Funny, sometimes I don’t feel like running an Ethernet cord through my home, and sometimes it has worked on Wi-Fi (work sites) and other times it refuses to load - and as soon as I plug in this stupid cord  - it works just fine…

This is quite cumbersome, it’s 2021 like “VPN” Ethernet just WORK jeez all these “so called security” protocols - data bases and data still getting hacked and sold - I don’t mind the “VPN” but we are in a wireless world - I almost feel like it isn’t a T-Mobile “issue” as much as its a silly “security” or some odd setting - also if the issue is with the MTU being the lowest on the T-Mo Nokia router then why don’t T-Mobile do a firmware update and just use the MAX size - what is the delay - I just dont understand - I wonder if my IT team will eve given admin access to try this - it really sucks because I don’t want to have to use Comcast - but yea the irony of not being able to use T-Mobile “home” internet and you…….
