I keep getting the warning message "decaps: rec'd IPSEC packet has invalid spi fro destaddr" for three routers using a site-to-site vpn. The users have complained about random lose of connectivity and this seems like the only thing that jumps out. The routers are Cisco 871's and they are connecting to a Netscreen 25 at our main office. Any advice on stablizing the VPN?
I have this problem too.
