firewall question

[Jessica Zhu]

Hi,

I set up the firewall on an old linux(7.1) server using ipchains which 
allows ftp within our network. After the firewall up, some users in the 
office who using Bbedit on Macintosh complained that they cannot ftp to 
the server any more although there is no problem to use other ftp 
programs.  

My final solution is to trust the ips from those users using BBedit and 
accept all from them. However, I thought this is not the best and secure 
solution. Just wondering whether anybody on the list can help me figure 
out the better solution.

Thanks!

Jessica
