Basic Configuration:
The Astaro has proxies in transparent mode, NICs are in bridged configuration. Upstream from the Astaro, I have another security device on the perimeter, for which TFTP must be used to update. Most LAN devices are downstream of the Astaro.
When trying to apply an updated image to the upstream device from a TFTP server (downstream of the Astaro), the initial connection is made and the transfer appears to begins, but then times out with no data actually being transferred. I understand that this is due to TFTP making the initial connection on port 69, but then choosing a random port for the data transfer and the Astaro is blocking this behavior.
I've searched the forum for solutions, but only a couple give vague instruction for how to fix that don't have enough detail to be actually implemented without alot of trial and error.
Has anyone here gotten the Astaro to let TFTP pass through and if so, what are the specific settings to allow this to happen.
Thanks.
