VPN and Sonicwall TZ170

bullseye1776 · 2015-01-06T16:07:36.000Z

We have a VPN setup for users to access our network shares from home using the Sonicwall VPN Client. This works fine except for when two people in the same home try to access the VPN at the same time. The first user will always connect but the second will not.

I was checking out the Sonicwall interface under USERS and LOCAL USER and noticed that we’ve been issuing the same username and password to all users. Can this be the cause of the problem? I’ve created a second user and will try from two machines at my home tonight but I wanted to get your opinion on if i’m on the right track.

Thanks,

Drew

That might be the case if it is detecting two logon attempts for the same user with the same IP.

Not sure of it is the username, but I notices when you have 2 different connection open to the Sonicwall (e.g. I have one for the SW management and one for the SSL VPN) and then I log-in as a different user in the SSL-VPN portal it kicks me out of the management session.

I think is is more of an issues with a connection from the same External IP address.

is there a way around denied connections from the same external IP address?

Yes. Two people can’t connect at the same time with the same credentials.

Larry has it right. You need to give each user their own login.

OK, so last night i tried connecting two laptops to the the VPN from home with two different SonicWall logins and only the first machine connected would connect to the VPN and the network. The VPN on the second laptop would get stuck at “acquiring IP Address”. Both laptops will connect to the VPN and can access the network when used one at a time.

Attached is Log information from the SonicWall.

Can you get the log information from the Client on the PC that couldn’t connect?

The log you attached shows one failure due to bad authentication and then a few seconds later a successful connection.

This was from the machine that couldn’t connect. it occurs to me that I might be coming at this from the wrong direction. maybe they second VPN is connecting and its just the virtual adapter is not getting a network IP address.

The last line of the log states: “Renewing IP address for the virtual interface (00-60-73-CC-F3-09)” and that’s it. When the second machine fails to connect, the status seems stick at “acquiring IP Address”

It’s been a long time since I’ve looked at those logs. Maybe you could attach a good one and a failed one for comparison?

What about the log on the SonicWall itself? I thought that was from the SonicWall because… well, that’s what your previous post said

Sorry, that is exactly what I said and what I said was wrong!

I will pull together logs and post later today.

Thanks
