I need to run nat box for ~2000 clients with up to 300.000 active connections. ipnat doesn't handle such load, so I'm going to try natd - but worry that natd will simply use all available outgoing ports and then crash. I have 128 public IP's and in ipnat's configuration just map smaller blocks of private IP's into certain public IP, but have no idea how can I do this using natd. Any suggestions? Regards, Andriy Korud.
