VDI Client (Java Applet) being blocked

andrewismith — Wed, 04 Oct 2023 15:21:51 GMT

Hi,

My wife works from home for NHS her laptop bring up a java applet for a VDI Client login, when she tries it while connected to a mobile hotspot it's fine, on wi-fi or ethernet it doesn't. Is there anything blocking VPN or VDI Client on my service?

I'm on Future Fibre. Thanks.

Regards,

Andy.

Which make/model of router do you have and what firmware version is it using? Which exact VPN client does your wife use

Hi andrewismith

Thanks for your reply.

Have you added the correct number? (I'm unable to locate any details) Do you have a FTTC or FTTP connection?

Hi,

Yes that's the number assigned to my account, in on Fibre 900 VoIP. Shall I message you my account ID?

Regards,

Andy.

Hi Andy

Thanks for your reply.

Are you using the eero or WIFI hub router?

Re: VDI Client (Java Applet) being blocked

andrewismith — Thu, 05 Oct 2023 09:01:57 GMT

Hi Debbie,

I am using the Wi-Fi Hub router, although I already switched it to another router (still got it) as I thought that was the problem. It didn't solve the problem.

Andy.

Hi Andy

Is the TalkTalk router connected at the moment? I would like to check the firmware version.

Could you also send me a Private Message with the serial number from the back of your TT router.

Hi,

Yes the TT Router is now connected. I will message the S/N.

Regards,

Andy.

Hi Andy

I still can't locate the router details. Could you send a photo by private message of the back of the router? Apologies for this.

Hi Andy

Thanks for the Private Message. I've checked and your router has the latest firmware version.

It would be worth factory resetting the router using the pin hole reset for ten seconds and then retesting.

Hi,

I will try the reset later due to work commitments and report back. However, doesn't this then mean that's it's not a router issue but something downstream of the router, within TalkTalk since I have the same issue regardless of router, but do not have the issue if not using TalkTalk (e.g. mobile hotspot)?

Regards,

Andy.

Hi Andy

How are you getting on, did you have a chance to factory reset the router?

Re: VDI Client (Java Applet) being blocked

KeithFrench — Fri, 06 Oct 2023 07:43:59 GMT

What about the VPN client (I did ask which one)? Is that connecting OK, as I presume that the Citrix is trying to work over that?

Re: VDI Client (Java Applet) being blocked

Hi Debbie,

Yes, router is now reset.

Andy.

Hi Andy

Thanks for your reply. Are you still unable to connect?

I can see that Keith has also asked a question about VPN.

Re: VDI Client (Java Applet) being blocked

andrewismith — Fri, 06 Oct 2023 08:03:42 GMT

Hi Debbie,

I won't be able to specifically say what VPN as it's on a NHS platform. Suffice to say, it is a secure java applet (VDI Client) that is triggered within the online application page, for logging into a specific NHS platform.

When my wife clicks to login, the applet does not even appear in the webpage when connected to wi-fi or ethernet. When she tries on mobile hotspot it is fine. When she takes her laptop to work on the hospital LAN, it works. Other colleague who have the same access on their laptops, on other IPS's at home, it works.

What we have tried at home, using Netgear Orbi router, the applet does not appear, TT router, actually worse, the whole application webpage page does not appear. I would deduce it is a parameter/restriction on the TT line or service.

Regards,

Andy.

HI Andy

Your current router has the correct firmware version that should work ok with VPN, I've not received any other reports of it not working with this firmware.

What is the firewall level set to on the router?

I can try sending another router for testing to rule out a fault with the router.

Hi @andrewismith

The VDI client is most likely a Citrix type thin client to load all the virtual desktops on. I appreciate the confidentiality aspect, but if you can confirm which protocol it uses for the VPN, then it would give a bit of a pointer:-

1. PPTP
2. L2TP-IPSec
3. SSTP
4. IKEv2
5. OpenVPN

I have tested as many VPNs as I can, on behalf of TalkTalk and am just trying to help.

I do not even know as yet, (as you haven't answered any of my questions) if the VPN connects OK over the TalkTalk router or not, before considering why the VDI isn't working. It is after all the most likely difference between working at home and being in the hospital.
