+# NAT/forward/vpn tftp
+
+I tried to get this working, but failed.
+
+tftp server in theory can be forwarded over a vpn, eg on a wireguard tunnel.
+
+However, I found that when actually pxe booting, it wouldn't work, only
+the 1st filename would be requested, eg, in the logs:
+
+Jun 20 23:51:02 kd in.tftpd[4021350]: RRQ from 10.2.0.12 filename pxelinux.0
+
+
+To get that far, nating tftp requires some special attention in iptables, like so:
+
+https://unix.stackexchange.com/questions/579508/iptables-rules-to-forward-tftp-via-nat
+iptables -t raw -A PREROUTING -p udp --dport 69 -s 209.51.188.0/24 -j CT --helper tftp
+modprobe nf_nat_tftp
+
+to test tftp from a client machine:
+
+tftp SERVER_IP -c get pxelinux.0
+rm -fv pxelinux.0
+
