Description bernhard.valenti 2000-12-14 16:50:01 UTC
when using ipnat's ftp proxy, eg:
have a rule like  map xl0 10.0.0.0/16 -> <outsideip>/32 proxy port ftp ftp/tcp
the nat machine crashes after downloading some files on a masqueraded
host via ftp. with crashing i mean: all network goes down, i cant use the
directly connected keyboard, it doesnt respond at all(except ctrl-alt-esc).
when i press the ctrl-alt-esc, it puts me into the debugger. then after some
time in the debugger even that stops responding, and i have to use the reset
button to reboot the box.

this does not happen when i remove that very rule from my ipnat.conf.
and that rule worked fine with 4.1.1-stable before updating to 4.2-stable.

How-To-Repeat: use ipnat's ftp proxy, and download some files on a masqueraded host via ftp.
it crashes usually between 5 and 15 files.

map xl0 10.0.0.0/16 -> <outsideip>/32 proxy port ftp ftp/tcp

i'm running 3.4.16 now on that box, which works fine.
did you commit any changes to ipfilter in -STABLE that make you think the 
problem should be fixed now ? if yes, i'll downgrade to the ipfilter version 
in -STABLE and try...
