- TFTP Fixed UDP Port:
CONFIG_TFTP_PORT
If this is defined, the environment variable tftpsrcp
is used to supply the TFTP UDP source port value.
If tftpsrcp isn't defined, the normal pseudo-random port
number generator is used.
Also, the environment variable tftpdstp is used to supply
the TFTP UDP destination port value. If tftpdstp isn't
defined, the normal port 69 is used.
The purpose for tftpsrcp is to allow a TFTP server to
blindly start the TFTP transfer using the pre-configured
target IP address and UDP port. This has the effect of
"punching through" the (Windows XP) firewall, allowing
the remainder of the TFTP transfer to proceed normally.
A better solution is to properly configure the firewall,
but sometimes that is not allowed.
