We have a vpn Tunnell set up between two SOHO3's. We are logging a workstation onto a Nt server through the tunnel. We are trying to run a dos application through the vpn, it works but is realy slow. We have dsl on the server end and cable on the other, we have the bandwith maxed out on both ends.sonic wall say's that we have the unit configured properly and the speed issue is with something outside of the tunnel configuration. Any help would be greatly appreciated.

It goes back to the transmission of data only being as fast as the slowest link in the process. While DSL and cable modem boast download speeds of 2Mb in some cases, the outbound speed is generally not more than 384Kb, if that. Check with your provider at both ends. And since you different broadband providers at each end, your data could be going hundreds of wire miles to get to the other side of town. A tracert would tell you how many hops and maybe give you city names of the routers involved. You may have a situation where data goes in one direction faster than the other way. You might try some file transfers between sites and see what kind of throughput rates you get each way, but try it in both directions.
