Hi In my opinion there's no reason why to block LANDs attacks with PF. I suppose that you have a windows server with private IP address behind PF and you use some portmapping for services you need accessible from outside. So if you want to make a LAND attack you have to make a packet with equal source and destination address but in this case it's not possible at all because everything goes to PF's IP address. As a matter of fact if your windows server doesn't have a public IP you're safe.

Is it possible to protect my Windows server from LAND attack with PF? I have tried searching Google and Benzedrine, but have not found any info. /Henrik
