I have a remote office which is connecting to the main office via a VPN between 2 sonicwall routers. The main office uses a sonicwall tz-170 with standard OS and the remote office uses a sonicwall tz-180 with standard OS. I am able to see the main office side, but my transfer speeds are VERy slow. I have a T1 a the remote office and 2-T1s at the main office. I have set VPN bandwidth management on the remote router at a gauranteed 1000kbps and a maximum 1200kbps and also set the main office side at a gauranteed 1000kbps and a maximum 1200kbps, both with a highest priority of 0. Even with this, it still takes me 27 minutes to transfer a 215MB folder. No, I am not trying to transfer files that large all the time, I was using that folder as a testing benchmark. I know it won't be as fast as the main network, but I should at least get that transfer down to 5 minutes or so, right?
