We currently have a Point to point T1 connecting 2 Offices and are thinking about upgrading the remote office to a 3 Meg internet Connection and having it connect to the HQ's 6 Meg Internet connection. HQ currently has a PIX515 and runs about 5 Home Office Point to Point IPSec VPN connections and a half dozen or so IPSec VPN Clients.
We were thinking of adding a Pix 515 to the remote office and have it Point to Point IPSec VPN into HQ. The Remote office has in it 6-12 people at any one time, and 1/2 of them use the connection to get to data at HQ and the other half is the internet. Should I bother with adding a VPN Accelerator Card (VAC) to the HQ PIX, should I add one to Both? at $3000 each, its a pretty steep investment.
