I am using DSL in office having VPN connectivity in a domain network.When we connect VPN it works wonderfully but its speed gradually decreases. Also vpn is auto disconnected after some intervals. I even made some other system as DSL server but the problem is same. That's why the system is not problematic. The DSL provider is also saying that there is no problem, then where the problem is actually.
DSL VPN Connectivity failures after regular intervals
DSL provider says, speed is OK however VPN is slow. We have to identify the root cause.
Possible problem: This might be an MTU issue and this need to modify. MTU size and need to determine the optimal MTU.
Possible problem: Takes 10 minutes to open and this caused by either LAN and of WAN and you need to run the application using Name instead of IP address.
Possible problem: Shared folders and remote access. This caused by NetBios and you need to use IP address instead of host name and TCP/IP only.
Possible problem: Download is slow after establishing VPN often caused by using remote network gateway. This needs to change the default from remote to local.
After doing the steps, VPN speed will be improved.
