I don't know about any of you, but I've been using IP Masquerading for
about 4-6 months, and through many kernels, many ipfwadm and masquerading
revisions, I have yet to be able to complete and actual ftp download.
Yes I'm using always defrag packets... Once in a blue moon the ftp
download will complete, but I can't execute or extract what I downloaded.
Usually it all just hangs at 99% complete.
On the other hand, in Netscape RealAudio (turned to TCP only), PointCast
Network, and http transmissions seem to work just fine. It is great for
browsing and casual use, but not a dedicated connection.
Has anyone run into this and solved it? (ie, am I making a stupid mistake
somewhere in my implementation?) I was under the impression that FTP runs
on top of TCP so that it should work just fine... only things like "ping",
ICMP, or anything on top of UDP would be affected.
