I wasn't sure where to post this so forgive me if this is the wrong spot.
I have a script that automatically TFTP's my configs to a server. For some reason it stop working. I tried to to it manually and it times out. It updtes the time stamp of the file in the /tftpboot dir. But it never buts the config out there. I was thinking this was a firewall problem but from what I can tell the firewall seems to be fine. I have no errors on my firewall (watch guard). I even ran policy checker and it allows tftp through. I ran wireshark and this is what I see:
I see the write request, file: abc.bkup\000, transfer type: octet\000
acknowledement, Block 0
acknowledgement, Block 0
Data Packet, Block: 1
then the next line in wireshark is ICMP
Destination unreachable (port unreachable)
This ICMP packet is the same source and dest as my TFTP transfer is. From the router I can ping the TFTP server with not issues.
Thanks in advance for the help
