    JK> Think I'll do that tonight in case that's the problem.. my

    JK> problem here.   
      
    ELS> Nonono... I don't think that... :-) You're configuration is ok if   
    ELS> your clients are using active ftp connections to your BBBS system.   
    ELS> But actually, all the current ftp/http clients are using passive   
    ELS> connections by default. Then, your BBBS responses are in passive   
    ELS> mode (without use of ports 20 and 21) but your firewall/router   
    ELS> don't forward the needed ports (1025 and above (unused)).    
      
   true... for the most part... port 20 is still used in the beginning, though...   
      
    ELS> As BBBS can't configure a port range for that, I must set all   
    ELS> unused ports for forwarding the passive responses from BBBS' ftp   
    ELS> to router/fw and back.    
      
   this depends on your firewall... the linux firewalls i'm familiar with use   
   conntrack to keep up with the connections... there's a specific module for   
   conntrack to use for ftp connections and it does easily manage passive   
   connections quite well... i've not had any problems with my ftp server and   
   have never even though to use its config for specific ports... it just works ;)   
      
    JK> Glad it worked for you :)   
      
    ELS> You can do it. I'm sure. ;-)   
      
   janis, maybe it is time to look at your firewall or put that modem in bridge   
   mode and set up a firewall similar to the one i run ;)
