I have implemented a few ASA firewall over the time and I have a question that I never solved.
There is an option on ASDM in the NAT screen that says " allow traffic between interfaces without NAT" or something like this. This option insert the "no nat-control" in the script and it is sopposed to allow traffic between interfaces without nat.
Even so every time I install a new ASA appliance and try to communicate Inside network with DMZ network I need an Static (inside,DMZ) or a "no nat" if I dont do that I see the error message:
No translation group foud for src x.x.x.x dst y.y.y.y
Does anybody knows why does it happens and if it's right to always need to use the no nat or static to communicate the two networks?
