You say the box "slows down to unreasonable speeds" and "crawls" - can you identify what aspect of the system is slow? Is it CPU usage, RAM usage, disk I/O, network I/O etc.? If this system is crawling when you're using a system behind its NAT interface, then that suggests the NAT rule processing is causing a problem ... Dave. -- Please don't CC me on list messages! ...
