Using TFTP on router outside the network

I am trying to copy the config-running file so that I have a backup of it off of a 1720 router. The router is located outside of our network with an external ip address. How can I copy if all I can use is tftp and the tftp is on our internal network. Is there another way to copy this file from the router?

You will need to make sure that udp/69 is opened on any firewalls between the router and the TFTP server. Alternatively, depending on the IOS and feature set running on the 1720, you can use rcp, scp, http, or https to copy the config.

Re: Using TFTP on router outside the network

Thanks for the advice. An associate here actually figured it out. We were able to connect to it via the internet using a telnet session and port forwarding on the router being used to connect us to the internet. Forwarded port 69 traffic and made the local system the tftp server. All is good, thanks.
