I've been doing this for a while now with FreeBSD 4.4-RELEASE on my spare Pentium 166 with 64 megs of ram and two Netgear FA311 ethernet cards. I originally followed the documentation on natd to set it up and I've had essentially no problems with this setup, it's been smooth as silk, with one exception. If I send files or other data upstream *through* the natd system (i.e. from a machine on the LAN to a machine elsewhere on the net) I have no problems what so ever ... but if data is sent from the FreeBSD system *itself* ... for instance someone remotely logging into my private FTP and transfering data ... the connection gets totally killed. Latency across the natd router goes through the roof. At first I thought I must be hitting some kind of upstream cap, but I get much better xfer rates and no crippling latency if I send from a machine on the LAN. If this is terribly obscure I appologize, but I've had this problem for a while now and I can't quite wrap my brain around this one ... ftpd on the natd machine sending a file to a remote client on the net cripples the connection with latency, but sending data (for instance with an ICQ file transfer from a windows machine on the LAN) *through* the natd router doesn't have the same effect. Has anyone encountered this? Any ideas on what might cause it and how to address it? -John To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
