VPN Troubleshooting

Hi all,
Have a VPN connection setup for a remote user but it's still causing problems.

Problem 1.
When user dials-up from remote office, cannot always connect which means we have to reset the VPN box (3Com OfficeConnect), why would this be happening?
Problem 2.
I have mapped the drives to our share folders and changed the entries in hosts and lmhosts files, but when remote user cliecks on the share folder they only see maybe one or two folders. Does this mean I need to get the user to right-click the share folder and make available offline? If so, on a slow internet connection will this take a very long time? Do these offline files sit on the users local hard-drive (and add 50GB extra !) and sync. with the server everytime they log on?

Be grateful for any help on this one, causing much strife in office at moment :)

can you please give me the default gateway and router you are using also please do ipconfig /all on server as well as on any on the machine and just send me that its looks like the gateway issue

Do you need me to connect to VPN and run the ipconfig/all , below is the ipconfig from my own computer connected in-house to the network, if that is any use?

        Dhcp Enabled. . . . . . . . . . . : Yes
        Autoconfiguration Enabled . . . . : Yes
        IP Address. . . . . . . . . . . . :

and can you confirm are you using the same default gateway as well on server

I see on my VPN dialup settings that under "Advanced TCP/IP Settings" > "General" Tab that the checkbox "Use default gateway on remote network" is un-checked

We are connecting straight to the Server IPaddress, then when connected via VPN we connect to to view the Shared Folders
What is the NAT pool IP addresses that your VPN concentrator are using?

Make sure that they do not overlap with the users home/remote IP range this can cause issues if the remote computer thinks it is looking for something locally.


Server network: 192.168.1.X
Remote user: 192.168.1.X
VPN Pool: 192.168.1.X

could change: VPN pool: 10.10.1.X
You could also eliminate split tunneling so that all network request go down the VPN tunnel instead of looking locally first.

ok I need to sit with the remote user and check out these issues re: VPN Pool.
With regard to my other questions:
1. Does this user need to make Network share folder "Available offline" and does he need to Sync with the server each time he logs on ?
2. Will making files available offline basically copy all files from server to his laptop and increase space being used on his local hard-drive ?
Even if the user was on a fast connection i would not make a network share a local folder. Not only will the space on the local machine decrease rapidly if the network share is used by multiple users it could take a long time to sync up.... not to mention that in the 10 years in the industry i have never had to do that on a vpn connection. Verify the settings first if the settings look right and you have disabled split tunneling then this is probably caused by the rules that the tunnel is working under.
