Hi, Thanks for the reply, Yes it happens in VPN tunnels from one particular box and towards 5 other ones also running 3.1.9. The other 5 PA500 boxes also have VPNs between them, but we see no packetloss on those VPNs. So I guess the quickfix to this, is to downgrade to 3.1.6, as I don't want to go for 4.0.2. Regards, Hans
