sendmail relay question

I have a mail server that is set up with sendmail on my network. the problem is the relay was working perfectly for all the machines with static ip addresses even if they connected form over the net.

I have FEATURE('relay_entire_domain')dnl in my m4 file and then add the users that I want to be able to relay to my /etc/access file.

everything there works great the problem comes when I set up some machines behind a linksys switch or behind any nat server. when I do this it stops relaying and gives me this error.

550 5.7.1 <>... Relaying denied. IP name lookup failed []

PS the ip address is my nat server if I add the ip address to the .etc/access file it will allow you to relay, I don't want to have to do this can't I just add the user to the access file and leave it at that? Does anyone know why this happens or how I can fix it? thanks for you time
