pkg_add blocked by IPFirewall

[Jose Borquez]

I am attempting to install cvsup using pkg_add -r but I keep getting the 
following error:

Error: FTP Unable to get 
ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-5.4-release/Latest/cvsup-without-gui.tbz: 
No route to host
pkg_add: unable to fetch 
'ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-5.4-release/Latest/cvsup-without-gui.tbz' 
by URL

I know that it is being blocked by my firewall.  What are the tcp and 
udp ports that I need to open up for pkg_add to get the package?

Thank you in advance.
