ASA 55XX File upload from internal TFTP server

By seth.phillips ·
(Remote) -vpn-> internet <-vpn- (hub) TFTP Server

I am trying to access an internal TFTP server (via the tunnel) from the remote site to update the code on the remote ASA. I have tried both the ASDM and CLI. I get the following.

copy tftp://x.x.x.x/asa803-k8.bin flash

Address or name of remote host [x.x.x.x]?

Source filename [asa803-k8.bin]?

Destination filename [asa803-k8.bin]?

Accessing tftp://x.x.x.x/asa803-k8.bin...
WARNING: TFTP download incomplete!

%Error reading tftp://x.x.x.x/asa803-k8.bin (Unspecified Error)

The TFTP server is working correctly. It sends and receives other jobs. It appears that the tftp command is only sending the request to the the external interface. How do I get this to work?

I can ping back and forth and all hosts can see and be seen. I am going to be placing these in foreign countries and I cannot until this problem is licked.

I ran into this problem when tftp'ing from my laptop (running pumpkin tftp server) over the network. I had too many applications running. Once I closed some apps, it transferred successfully.

Disable wireless

I ran into this pronlem. In my case the ASA was not on the network. I connected my laptop to the ASA and put both on the same subnet. However, my wireless radio was on and no matter how many times I tried or TFTP software I used I kept getting the same error. Finally, I turned off (disabled) my wireless and it worked!
