Basically when I have a normal 1 to 1 static NAT it works. Working meaning mail is flowing but as soon as I do the port redirection the pix takes the commands but mail does no longer flow, or HTTP cannot be connected to.
I'm not sure if it's something in the config but all I know it only stops responding with port redirection is turned on.
I completely agree with Mr. Ddialvo .I have faced similar problem but had to sacrifice one more public IP.I used one public IP and redirected port 25 and port 443 to respective internal and dmz servers.It worked for a while but after sometime it stoped receiving port 25 traffic.Poor chap ,I had to do 1 to 1 mapping for 25 and 443.Now with many people facing same problem,I am assured it's a BUG in Port redirection.Hope Cisco will resolve it.
I would rather tell you why my lines are different by looking at your config. Post it without passwords and last two octets of public ip's. Your lines look correct but if you are doing port redirection based on the outside interface, then you need to use "interface" as shown below.
