Take my results with a grain of salt however since I do this on a moving train. :) OK, so I see no difference with a higher setting here.

I won't be connecting that way for a while, but when I do, I'll try the faster maximum and see if it changes anything. I was on last night on the train ride home and did a 14MB upload to my ftp server. The maximum throughput I got at any time was 16KB per second. But the train is a tough environment because cellular coverage is spotty and signal strngth varies all over the map. My default was 230400, but I have never tried a larger number.

If you go under network settings and choose the properties of the blackberry dialup device and then "Configure" to drill down to the baud rate of this device, default is 115kbs, I can change mine to 980kbs... I now see spikes to 560kbs on the upstream... Have you seen this tweak?

It is a failure of the remote server or cellular host to connect. It may be that this setup uses a port that your IT guys have blocked. I'd check with them on that.

I'm using the microsoft XP VPN client. I'm getting the error 721 when I try to connect. I can disconnet my blackberry and go back to regular wireless and VPN comes right up. So far, I can't seem to find anything or anyone that has had any luck or issues, other than you. Thanks for your input...its helpfull Mattie Thanks for getting back with me so quickly.

We use the Shiva VPN client. I had no issues at all, but speed can be a problem. VPNs are more sensitive to weak or slow connections than, say, Instant Message clients. I use the tethered modem connection (EVDO) with the VPN just fine in general. It works best when I am in a hotel room saving $10 per day as opposed to on the train and in transit. Signal can be spotty then due to tunnels or coverage gaps. In that situation, I have to reconnect on occasion. SOmetimes I do just give up. Mattie, thanks for stopping by and for your question.

I'm having issues getting mine to work so was curious as to what vpn client you were using and if there were any special settings you needed to add or change. thanks Mattie I’m curious if you had any issues getting your office vpn to work.
