Well, we had it between 2.2.7 and an OS/2 Warp (3? 4? patches? - cannot remember). We had to change the ethercard to another _type_ (and driver :-) on the os/2 machine. The interesting thing was, ftp was perfect in one way, and incremental slowdown on the other. (we cannot wait an ftp of a 100K file) And yesterday, I've found a similar problem between 3.[12] and W*. local net with 192.168.x.x --- FBSD ed0 192.168.x.y ----------- | | ed1 real IP to BigBadNet | ---------------------- Everything was OK (not perfect, but it's running), the local machines can surf, etc, but ftp from localmachine -> fbsd: one way good, the other way sloow (_not_ slowdown, only slooooower - but we _can_ transfer >M files opposed to the previous problem). The problem was, that natd is running, but! configured to the _wrong_ (ed0) interface. After configuring it to the correct interface, (a messing typo) it's fine.
