I have a Cisco VPN Concentrator that remote users connect to/through so that they can use Network resources. There are usually 10-15 connections on any given day and they are sending and receiving data just fine. Every now and then, a connection will get terminated and at times a connection will be dog slow.
I can go to Administer Sessions to get statistics on who is connected, how long they have been connected, from where are they connected and can even ping the address to which they are assigned. When I get a 25ms return on the ping and see that they have enormous Tx/Rx rates, I know they have a solid connection.
I guess I have a couple of questions:
1) Why would several users at the same location have differences in connection, i.e. user 1,2 & 3 connects and is Tx/Rx fine and has the normal 25ms ping where user 4 connects and he is having all kinds of issues with the connection?
2) What "things" could cause this?
3) Is there a way to increase the throughput or "open the pipe" on the concentrator to make things faster?
