Trying to download a file from a Cisco 2811

I'm trying to download a .png file from a router.  The following line is in the config:

tftp-server flash:desktops/320x196x4/willis.png

I'm using tftpd32.  The Current Directory and Server interfaces are static.  I've tried several different formats for the remote file:

flash:/desktops/320x196x4/willis.png

flash:desktops/320x196x4/willis.png

flash/desktops/320x196x4/willis.png

/desktops/320x196x4/willis.png

desktops/320x196x4/willis.png

None of these are working - it always times out on block #1.

This seems like it should be simple.. any help would be appreciated.

Hello Kristen,

Is there any firewall in place between the router and your TFTP client? The TFTP uses the UDP port 69 for control connection but for subsequent data transfers, it may open arbitrary ports. An exemption should be temporarily added to all possible firewall rules in both dataflow directions to allow unobstructed communication between the IP of your router and the IP of your TFTP client.

Best regards,

Peter

Well, the firewall is in the router but I went into Windows Firewall on the server and enabled inbound traffic for tftpd32.exe and it worked.  Thanks!
