avoid snat rule for internal to DMZ traffic

I have an https SNAT rule that allows my internal traffic to all out the external and SNAT's it to the external. The problem is when my internal traffic tries to https to the DMZ, the SNAT rule applies, and the DMZ hosts see traffic coming from the external IP. How can I set up a rule to allow internal hosts to get to the dmz and avoid the https SNAT rule? Much appreciated if someone has a tip. Thanks!
