Static and Dynamic NAT

Hello to everyone. I have an issue here and I will appreciate if someone helps me in this. I have Astaro Firewall and I have configured 2 interfaces local interface and WAN interface. My question now is this, how can I make dynamic translation of IP addresses of my computers into my public IP addresses pool or make translation to my WAN IP address look the network diagram of my network. Secondly I would like to make static NAT for my servers so that they will have every time the same public IP address for outgoing and ingoing traffic.



Before this firewall I have used Cisco Router 1840 and my configuration for NAT-ing is the following code:


ip nat pool dynamic X.X.65.1 X.X.65.62 netmask 255.255.255.192
ip nat inside source list permit pool dynamic overload
ip nat inside source static 10.10.0.128 X.X.65.63
