I have an exchange server sitting in my DMZ, IP addy 10.x.x.x. In my pix I made a static(DMZ,outside) 10.x.x.x 208.x.x.x, to NAT the 10.x.x.x addy to a public IP of 208.x.x.x, also in the PIX i added acl putside permit tcp any 208.x.x.x eq smtp. In my outside router i added a permit tcp any 208.x.x.x eq smtp entry. Will this work? Any help would be great.
