On -current with a simple NAT setup Windows and Mac systems are  
unable to FTP through the firewall. The setup I'm using was  
previously working.  There are a couple of open PRs that were filed  
in 2006 describing the problem.  Basically the FTP connection hangs  
after doing the user and password handshake.   The problem has been  
reported on systems other than NetBSD and it appears to be related to  
a bug in ipfilter that seems to have been fixed in Dec 2006.  However  
after updating to -current I noticed the bug is still present and the  
version of ipfilter is still 4.1.13 (latest version of ipfilter is  
4.1.17).  Comments in the logs on the coombs.anu.edu.au/ipfilter site  
indicate the fixes were put into NetBSD -current on 24 Dec 2006. Did  
they not make it into -current or do I have to wait for the import of  
the latest version of ipfilter?

Thanks
