[Asterisk-Users] TFTP Server Facing the Internet

[Michael Welter]

Since we're chatting about tftp servers...

Let's say I have a new customer with Cisco 79xx phones, and he desires 
to SIP register on my Asterisk system.  I would have to provide the 
SIP<mac>.cnf and SIPDefault.cnf files on my tftp server for his phones. 
  These files would be world readable, which I don't want.

Is the solution to put the tftp server behind the firewall and port 
redirect based on the customer's IP, or is there a better way of 
restricting access?

Thanks,
Mike
