As you can see no pkt is leaving. If it were leaving S, but A were not receiving then I would think firewall is dropping it.
[ S ~]$ sudo tcpdump -A -nniany host 192.168.1.10 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on any, link-type LINUX_SLL (Linux cooked), capture size 262144 bytes
Most likely the firewall on the system running your tftp client is blocking the traffic from the tftp server. The easiest way to test would be to put in a rule that allows all packets from the server (or to at least log them so you can see what's happening). The firewall issue is most likely *not* with the tftp server.
