Three 5G internet blocks Pulse SEcure (ivanti) VPN disconnects

Three5GVPN — Tue, 20 Jun 2023 18:57:14 GMT

I saw some other posts of this topic with NO solution, and yes, another Three 5G user suffering the same problem with VPN, with Pulse Secure.

Let me explain:

I got a really good 5G signal, no issues, but when connected to the VPN Pulse Secure (required for work) the connection drops every 3 minutes. Yes, exactly 180 seconds. That makes work remotely impossible...

Company IT team has been looking into it unsuccessfully. Finally we tested the same Laptop and the same VPN Pulse secure doing hotspot from another 5G internet provider and it worked fine.

So the problem is only with Three 5G.

I have also contacted with Pulse Secure support team. They have investigated and concluded that is the Internet provider blocking the connection every 3 minutes.

All this makes me feel switching provider...

I found this link, more people having very similar cases.:

https://community.pulsesecure.net/t5/Pulse-Connect-Secure/Connecting-via-hotspot-or-5G-modem-Three-Z...

I got external technical support guy suggesting me that there is nothing to do on the router Setup, since this is the Provider (Three) network affecting negatively to the VPN. I have tried the 5G broadband sim card in a phone and same issue. But on the same phone, doing hotspot with another sim card then it works perfectly. The issue is only with Three network. Already done so many checks that this is a fact: Three UK is blocking Pulse Secure VPN. this makes impossible to work from home. Therefore Three 5G broadband useless and unless there is a solution I will need to switch provider.

I am facing the exact same issue. I use 3 5G sim as a hotspot and pulsesecure. The connection terminates in three minutes and it kills all the putty and DB connections.

I’ve been having an issue with NORD vpn and it only connecting over the vpn protocol IKEv2 instead of the supposedly faster and more secure ones (Openvpn! NordLynx). I read on another forum that changing my APN (in mobile network settings) from three.co.uk to 3internet would resolve the issue, and so far it has.

Do a search on this forum for VPN and you will find that this is a recurring problem. Some VPNs work with Three Broadband whilst done do not. It is all somewhat erratic and whilst I have been OK recently - my employer uses Cisco AnyConnect VPN - my confidence that I will not encounter problems in the future is low.

You should try changing the APN setting from "three.co.uk" to "3internet". The two are two different network setups - the latter is more likely to work with games and VPN's. Find that in the router settings under "Network setting > Broadband > Cellular APN"

There are two router settings to try too:

* turn the security level down. On the router, in the menu, choose security, Firewall, choose Low.

* You should also enable the DMZ. Log in to the router (see the label on the bottom of the router). Then in the menu, go to Network Setting > NAT > DMZ. Enter your machines IP address in the box - you can find that on the home screen of the router, click to expand the "connectivity" box, and see what it says for "IP".

Note that both of these settings make it easier for someone evil on the internet to connect to your computer - so you should make sure you have your machine updated and a password more complex than "hello".

Hi Everyone,

I've noticed a few discussions cropping up about issues using VPNs over Three Broadband connections recently. I'm sending everyone that has mentioned this so far a PM so that we can get you in touch with some colleagues that will verify your accounts, and gather more info to help us investigate.

If you're experiencing this issue but haven't posted yet, please add a reply so that I can get in touch, the more examples I can gather, the easier it should be for our support teams to pinpoint what's causing the issues.

Hi everyone,

If you're experiencing issues with VPNs can you try the suggestions on the thread

Let me know if the info there helps.

Thanks,
JonathanB

This doesn't solves the issue with Pulsesecure VPN

Hello @sridiyer

Are you saying that you have tried the suggestions by both @Hello1024 and by @JonathanB and that neither worked for you ?

JonathanB — Thu, 27 Jul 2023 11:05:47 GMT

Hi @sridiyer,

Ah that's frustrating. It looks like there have been quite a few other issues with VPNs that were fixed by the advice on that thread. So you changed the APN to manually connect to 3internet, and you're still getting disconnected every few minutes?

Re: Three 5G internet blocks Pulse SEcure (ivanti) VPN disconnects

sridiyer — Fri, 28 Jul 2023 09:13:11 GMT

Hi @JonathanB

Yes I changed the APN to 3internet and PDP type to IP4. It still keeps disconnecting after 3 minutes when I use pulse secure VPN.

Thanks

Hi @JonathanB are you still looking into this?

I am having a similar issue, but not so severe. My company uses ZScaler VPN and it disconnects on average every hour (it's quite variable when it will disconnect); all other devices in my house are unaffected when my laptop loses connection.

If I disconnect from the WiFi and reconnect then the laptop is able to connect and works fine again. I've limited to IPv4 and tried both three.co.uk and 3internet APN but the issue persists.

Is there anything else to try?

@Sguppy

Have you checked the ZScaler VPN website to see if they have any technical support articles concerning the use of their VPN with 5G Broadband ? It might also be worth having a word with your company's IT support ; they might be interested in the problem and they might even have encountered it previously and have a solution.

As @JonathanB is aware, I am keen to acquire Three 5G Broadband, but I am reluctant to do so until all of these VPN problems are finally resolved.

JonathanB — Thu, 17 Aug 2023 11:53:59 GMT

Hi @Sguppy,

Thanks for alerting me to this. I've not had any mention of ZScaler so far, however what you're experiencing does seem to be similar to what some other customers are saying, albeit they're getting disconnected every few minutes, rather than about once an hour.

As the APN fix doesn't work, I'll message you to get you in touch with some colleagues that can help gather some details for us to investigate this further.

Hi, I am also having this issue starting from 2 weeks ago (it was working fine for me for nearly half year). I have tried changing the PAN to three.co.uk and using ip v4 only, but it seems not working for me.

Another user here suffering from the problem with Pulse Secure - it's a pretty major problem / failing!

Any update on a fix?

Re: Three 5G internet blocks Pulse SEcure (ivanti) VPN disconnects

sridiyer — Wed, 23 Aug 2023 14:17:58 GMT

Hi @JonathanB

I changed the APN manually to 3internet. My PulseSecure VPN connection still drops after 3 minutes.

I tried everything but still it wont work.

Can you try changing your companies name from 3 internet to 10 internet and see if my connection stays for 10 minutes 😛

JonathanB — Wed, 23 Aug 2023 14:28:36 GMT

Hey @sridiyer,

I appreciate your frustration with this. Did you see my last PM? If you can send me some recent example times when the disconnections have been happening that should hopefully help our support teams in finding the root of the problem.

Thanks,
Jonathan

Hey @Dan1981,

Sorry we've not located the root cause yet, but any data you can give will hopefully help with that. I'll PM you to get you in touch with some colleagues that can collect some info that will help us investigate.

Hi,

I am also facing an issue with connecting to my office VPN and spent over four hours with 3UK technical support but they were unable to provide a solution and finally without any resolution they have closed my complaint.

Now I am seriously thinking about switching the provider.

It's really disapointed
