I have a PIX 515 at our headquarters. I have set up 2 branch sites with IOS routers with VPN capabilities and they are connecting to the HQ PIX. Several times each day, the branch offices report that they lose their connection to the HQ PIX. This causes problems with SAP and other applications they are running. Any ideas what is causing this or how I can troubleshoot?
