New Fiber Line making VPN unstable
Posted on 2010-09-06
We recently upgraded from a T-1 line (1.5mb) to a fiber line (10mb) with the same ISP and kept our same IP address. Since the upgrade about 1/3 has seen speed improvements, 1/3 see no change and 1/3 are getting booted off after 2-3 up to 20 minutes after connecting. I'm connected right now from home and while I'm copying files of the server to test find that after about 20 minutes I'm disconnected. I've not changed anything at home and before we upgraded the office the VPN would allow me to stay connected without a glitch for days. I had a remote user connect on Friday to the VPN and she is still connected despite not touching her computer all weekend. I have a user that can connect from his remote office and stay connected but when he takes his laptop home and connects he gets kicked off after 2-3 minutes. Any ideas where I can start looking to fix this issue? Thanks.
I'm running Windows Server 2003 behind a Sonicwall 170 firewall and have the VPN on the server. I'm connecting from home using Windows 7 but all other users have XP SP3.
