I have a cisco firewall with a /30 internet connection. There is an outside interface and an inside interface connecting to a switch where clients sit in..
All clients coming from the internal network are patted to the outside interface in order to reach the internet.
I now have a server on the internal network that i need to access form the internet. Is it true that i cannot make a static nat statement and pat into this server on port 443 using the ip-adress of the outside interface? Do i really need a /29 and more ip-adresses in order to accomplish this? If no how would i go about natting to my server? Everytime i attempt to nat asdm tells me that my nat statement would overlap with the outside interface.
