I have another interesting thing that happens with NetBSD and IPNat, if
I try to download a file larger than ~12MB the whole NetBSD box will lock
up freeze completely and the only way to go on is to power cycle. (LC475, 36MB of Ram, full 040, 56K Supra modem) Any ideas?

Cheers, Paul.

It's probably your modem that can't handle baud rates between 38400 and
57600. At least I haven't seen any modem that will accept anything other
than the "standard" baud rates (e.g. 9600, 19200, 38400, 57600, 115200,
and some lower ones, maybe a higher one). I'm pretty sure NetBSD itself
can do odd baud rates though (perhaps useful for null modem connections
between two machines).

That should work fine then... that's what I do, actually. I get a dynamic
IP address, but I use pppd's demand dial mode with a 90 second timeout.
Sometimes I leave a telnet connection idle for too long and lose it, but
stuff like web browsing, email, and ftp work great.
