I have a request to allow couple of hosts from Internal Network to DMZ Zone host through port 25 for SMTP emails . I can create static , but that will open all ports . I created an access list from Inside hostto DMZ host eq 25 and created Static also. After applying this access list rule , it blocked the whole traffic through Inside Network.
I did this configuration through PIX PDM GUI .What went wrong ?.I deleted the access list which I created and pix started working normal.The PIX IOS ver is 6.3(3)
