I have an issue that I am trying to figure out how to fix it. What I am trying to do is this, I need to be able to have a machine on the inside network make a call to a machine in the DMZ using its outside number. I have a 1 to 1 NAT setup for my DMZ devices. I can talk to the devices using their internal numbers, but if I try to connect to their outside number from inside the network it won't work. I have been told that there is an ACL on the system that is blocking this from happening but I can't seem to find it. I did not setup this firewall so I am at a loss as to what is going on.
