One of the problems we had was that TFTP can be both UDP and TCP. When VOIP was initiated {we run phones on remote sites through our VPNs for config} we had the problems you described, it was not until we noted our illustrious new firewall admin had opened TCP 69 and not UDP69. Once that was opened to the remote networks, everything started to work fine. Our firewall logs show that the Cisco & Mitel phones all were trying to pull on UDP 69 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have tried that. The reason we are using TFTP is for our VOIP phones to pull down the config setting upon reboot. Over all I prefer SCP or SFTP but in this case its not avaliable. Akash Rao wrote:
Craig, It is tough to know what might be wrong without checking the logs of
the
firewalls. I hope you have tried to telnet to the tftp server on port
69
(default port for tftp) from a client in remote lan and confirmed that the tftp server is running. Now, try the same test with a client in
"my
lan" and confirm the same. On a seperate note, i would suggest using scp or sftp rather than tftp to transfer files. Since these are more secure.

I have all the proper rules for so I can remote connect to servers on the other side, and ping works fine. However I'm trying to use something like tftp over from my lan to the remote lan. It does not seem to work. Any ideas? Thanks Craig
