Hi all,
Thank you for help me in configure NAT ... It´s working perfectly!!!
One another doubt...
where my public address = 200.X.Y.Z
and my trusted addresses = 201.1.2.3, 205.6.7.8
I want to only liberate the access to IP 200.X.Y.Z
for addresses: 201.1.2.3, 205.6.7.8 and to block for the remaining portion of the world.
You can help me?
