I`m using the Cisco ATA-186 (voip), which supposed to get configuration updates from tftp server.
After I moved the device behind the m0n0wall, it`s not pulling the updates anymore.
I can see in the logs that m0n0wall blocking the return connection, so the ata initiate the
connection ( tftp - udp port 69), but the answer from tftp server is blocked (udp high ports).
Thanks in advance,
