TFTP new software onto ASA from a TFTP server on other side of VPN tunnel.

If you need to TFTP new software (or any other file for that fact) onto a ASA from a TFTP server that is on the other side of a VPN tunnel, you will need to specify the source interface for the TFTP client to use.

The easiest way to do this, is to specify it inline with the copy command:

 copy tftp://;int=INSIDE-management disk0:/asa842-k8.bin

Where, is the IP of the TFTP server. INSIDE-management should be replaced with whatever interface you want to use as source.
