[cobalt-users] raq 550 and ftp - strange problem...

["> freitag lab. ag / nafroth" <seb@xxxxxxxxxx>]

hi there,

there's a strange problem with proftpd on my 550 and i don't get the
point...

my raq is behind a nat device and working really fine - web, email -
everything smooth and fast.

i do have some customers sitting behind nat routers with very ristricted
access via closed ports and they always get full 800 kb/s with up and
download via ftp.

some others also behind nat routers like linksys, dling, astaro (home and
soho stuff) even with all ports open should get 100 kb/s, but it is only
bout 18 kb/s. no infos in logfiles, no errors.

i already tried to play around with pasv port range and ip masq in
proftpd.conf but it won't work.

no bandwidth limits are set.

any ideas? this really drives me crazy...
