The obvious is to check that port 20 and 21 are open in the firewall.

These are the ports FTP uses.

Subject: Re: [HP3000-L] can ping, but can't ftp

I have customers from all over the world logging to my system via FTP
and
transfer files back and forth.  There is this one specific customer, who
used
to logon and do FTP.  However since we changed our DSL (supposedly
upgraded to
a faster one - which of course changed our IP address) they get  timeout
when
they try to FTP to our site.

Around at that time they installed a firewall at their site, but they
swear
that they are not blocking our site.  And here is the strange part:

I can go to their site and ping any one of my customers and  actually be
able
to use FTP to go to those customers.   I can ping our  site from their
machine without any problem as well, but the minute I go to ftp  and try
to open our
site... it sits there for 3-5 minutes and than comes back  with timeout
message.  It seems it is only my site that their HP is having  problem
to connect
to.  Can the problem be at my site?

Any help, comments or directions will be appreciated.

Thank you in advance
