Microsft VPN and sprint cell connection
Hello Everyone,
The scenario is:
We have a laptop that connects through a datacard (sprint) and then connects to a microsft vpn.
The issue I am having is that once we connect to the vpn, within a few minutes we get disconnected from both the vpn and cellular connection.
What I find starnge is that if i just connect to the cellular network (using my datacard) the connection remains established until i disconnect, as soon as I dial our vpn, within a few minutes we get kicked out and both networks disconnect.
Any suggestions are very appreciated.
Thanks in advance

Can you use regular internet while your VPN is actively connected and in use? ... Thinkpads_User

yes, i can browse. Within a few minutes (less than 5) i will get disconnected from both connections.

For example. I have connected to my cellular data network (not connected to vpn yet) and have been browsing for more than 5 minutes. (I have tried it on multiple laptops and as long as I do not connect to the vpn I dont disconnect
It would appear to be something with your VPN connection.
Take one computer, try it with a wired connection and see if VPN disconnects. Then try again with cellular.
My USB Celluar provider (same company as home internet and TV) has changed their service so that I need special service (read: extra cost) to be able to connect and browse the remote end of the VPN connection.
Ask Sprint if you need special service. I did. .... Thinkpads_User

If i plug the laptop to the network (ethernet) we dont get any type of disconnect.
So then, in all likelihood:
(a) Sprint does not fully allow VPN usage (has happened to me with a different ISP), or
(b) Microsoft VPN has an issue with cellular cards.
You said above that you checked the routing and remote access policies. Are there other policies for VPN you could review?
There is an article about VPN disconnecting (but not involding cellular cards). Still worth a look.

No other policies, so strange, one laptop is plugged into the network via ethernet, the other is on the cell card, I was on the vpn for about 5 minutes then we got disconnected from the VPN but I am not being disconnected from the cell card.
So then there is some issue with Microsoft's VPN. Did you the articles referrenced in my link? There are a number of sublinks. However, I can see from a quick google that you are not the only one with Microsoft VPN disconnection issues. ... Thinkpads_User

dangit.....i wish simple fix, it looks like I have an all nighter....Yes I read the articles and may attempt to change MTU size. I will post after I try. Thanks for your help
MTU (Maxiumum Transmission Unit) normally affects speed but (normally) does not disconnect.
It is getting late here as well, but I always try to monitor emails, so I will attempt to help when you ask / when I can. ... Thinkpads_User

Also, don't forget to follow up with Sprint. Their service may be responsible. ... Thinkpads_User

What i am trying now is:
rasdial vz (cell)
rasdial ssa(vpn)
and no disconnection issue.
I didnt mention before that we have a batch file running as soon as the user logs in to dial these connections and to connect me to the TS. Once logged into the terminal server is when the connetion drops. Disconnecting the terminal session, the vpn connection and the cell connection.

please close. we have determined that its an issue with the cell serivice provider
Is that not what I suggested in my post #36526409 ? It is a common issue. .... Thinkpads_User

Oh yea btw, according to sprint they dont requiree any extra fees to be paid in order to use the card for vpn. and yes If i use a wired connection vpn does not drop

Issue is not resolved. This comment only identified a problem that was obvious.
Sorry I could not get you farther along. I did try, so thank you for following up and closing. ... Thinkpads_User
