We have a Cisco ASA 5505 running 8.2.(1). It is runnng two site to site VPN's. The VPN' stays up, but after awhile, it will stop passing traffic. If we log into the ASDM, and we logout the VPN session and let it get recreated, it creates the tunnel, and traffic starts passing over it okay. It may pass traffic for a few days, then traffic stops. I have maxed the crypto lifetime size as well:<br />
crypto ipsec security-association lifetime seconds 28800<br />
crypto ipsec security-association lifetime kilobytes 2147483647<br />
<br />
<br />
Thoughts?

Cisco ASA 5505  IPSEC VPN stops passing traffic

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).
