vpn issue

Hi,

I have a web application that is being used outside of my network from different users in different places, and because it is only one or 2 pc's per site we are using the Global VPN from Sonicwall and my firewall is the NSA 240. I have 2 scenarios that I am not able to understand:
 - when the user is using the application trough the vpn the application becomes very slow
 - when the user is using the application outside of the vpn the application runs smoothly.

Also I have a another issue: I have the vpn connection enabled in my notebook, and when i am outside of the network I need to go inside of the network to check the servers, and now after sometime I have only access to 2 servers the others I dont have. I used to have access to all my servers but now i dont have.

Thanks

right for first question, I take it you meant when the user logs in directly via internet address it works fine and when VPN'ed in performance is slow.

could be many reasons. The VPN user, is the user wired/wireless. If wireless then though it will be fast when connecting directly but performance will degrade upon tunneling in so advise user to use wired connection is the first thing I would do.

if you can VPN in to your networks, then I cannot see any reason why you shouldn't be able to access your server unless you are using DNS name and there's a mismatch. why not try and use the IP address.

Can you ping the servers when VPN'ed in. If you can then you should be able to connect. if you cannot ping them then another way to log in would be to log in to one of the servers you can log in and then RDC from that server to the other server where you cannot log in.

Also, you can try pinging the server via the server you are able to log in.

what kind of servers are those anyway? and have you got remote management enabled. are there any other admins who might have changed something which you aren't aware of?

Hi, for the user internet connection, it is a wired internet and normally the connection in most of the sites are from europe and USA and the bandwidth is more than 3Mbps. My connection here in the central site is 8Mbps a fail over access is 1 Mbps.

For the issue of the access to the remote servers:
 - they have remote access enabled
 - the configuration didnt change like gateway
 - I am not try to connect trough DNS Name as I dont have access to the internal DNS to resolve the internal names
 - For the servers that I have access it pings but the ones that I dont have access I cant ping.
 - The servers: 3 x windows 2008 and 4 x Windows XP that have comunication services for the applications and I have only access to 2 windows 2008 and 1 Windows XP.
