I have a Cisco 871 Router (AdvIP IOS). I use the 871 in a remote office (connected via Public ISP - 2Mb downstream/10Mb Upstream)to automatically create an EZVPN tunnel back to a Cisco 3000 Concentrator at our HQ.
There is a Cisco 7960 IP phone connected to the 871 and a laptop (new) connected through the IP Phone.
The VPN tunnel comes up fine. The User can log into the network fine and access all network resources (DNS, File Server, Internet, Intranet, etc.).
The problem is that that overall data throughput is very slow. It can take 2-6 minutes to open 60Kb files (e.g., MS-Word, MS-Excel).
I have modified the "IP MTU" on Interface Fa4 (WAN Port) to adjust for overall MTU size (I have not done this on the Concentrator yet). I have configured the "ip tcp adjust-mss" command to change the size of the packets.
I'm looking for any help into any/all things I can should look into to identify how to resolve/alleviate this issue.
I've also had the MTU on the laptop (in the OS) adjusted down to 1270.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
