This is true. I enable compression in ssh, but disable it in PPP. Still, I suppose, it is imperfect. I'm wondering if changing the MTU/MRU will help (and in what direction). It does, however, completely emulate the net interface -- I can ftp, rsh, run X, etc. over such connection -- even rwhod works (must be started after the connction is established). > > This works perfect to get a normal connection through a one-way > > firewall too, BTW. > > Which is the only reason I use it. -mi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
