Gavin et. al., Attached is a simple bash script that carries out the procedures listed on enabling NAT on LTSP/Edubuntu servers. I checked the script out fairly extensively but would love to get some feedback from the community on its overall utility. Despite the awesome instructions on the ThinClientHowtoNAT, I found NAT to be difficult to setup because each detail is important. Perhaps I am not very good at following instructions to the letter - a conversation for another time.
NATscript takes all the mystery out of the operations and may help new users setup their servers quicker.
