50000-50050 are the ports used for transfer. Depending on the type of ftp client you have port 20 (active) might be needed instead of 21 (passive).
Polycom (non eol models) are PASV clients, and vsftpd in sipx is configured for ports 50000-50050 for data by default. Also, I typically tweak the vsftpd.conf file to include the PASV address too. http://track.sipfoundry.org/browse/XX-8904 On Thu, Apr 5, 2012 at 2:02 PM, Nathaniel Watkins < [email protected]> wrote: > For some reason – I have 20,21,50000-50050…**** > > ** ** > > *From:* [email protected] [mailto: > [email protected]] *On Behalf Of *Michael Picher > *Sent:* Thursday, April 05, 2012 1:59 PM > *To:* Discussion list for users of sipXecs software > *Subject:* Re: [sipx-users] remote polycom cannot find boot server**** > > ** ** > > I checked our firewall at the office and we only have 21 open in pfSense.* > *** > > ** ** > > Mike**** > > On Thu, Apr 5, 2012 at 1:56 PM, Tony Graziano < > [email protected]> wrote:**** > > are you including a way to add the PASV ports to the iptables framework > too?
