Tranfer config files via tftp across a WAN

Is is possible to use the command "copy run tftp" on a router that is on another subnet from the tftp server via a T1? I get %Error opening tftp://x.x.x.x/router-confg (Timed out) or undefined error. It works fine when the router and the tftp server are on the same subnet.

Thanks,

RJ

Re: Tranfer config files via tftp across a WAN

You should be able to copy to/from a tftp server anywhere in your network. You should try pinging the tftp server from the router to make sure that it is reachable. Other issues may be a firewall between the router and tftp server or a problem with the server itself.

is there an ip helper address pointing to the host ?

Make sure you tftp server has a default gateway configured.

BTW: Across the WAN, I usually prefer to use FTP. That gives you a much better performance.

Thanks for all the responses.

Across a WAN, you need to specify the LAN interface as the source since protocols will use the serial interface for the source since that is the interface where the route points to for the server. NTP works the same way when you have an NTP server setup across a WAN. I setup "ip tftp source-interface fa0/0" and it works great.

Thanks,

RJ
