Dynamic IP in PIX Firewall 525

[fajarkusmelia]

Dear all,

I have PIX Firewall 525 series, can I use Dynamic IP and overload so one public IP can be used by more than one of private IP if I NAT private IP to public IP in this firewall.

And how is the configuration (command)?

Hello

Yes. you can use PAT on firewalls. You can use the following commands on the PIX 525

nat (inside) 1 192.168.1.0 255.255.255.0 (your inside network)

global (outside) 1 interface

By doing this all the IP addresses in 192.168.1.0 subnet will be going out with the PIX outside IP address.

All the best !!

Do not forget this commands:

ip address outside dhcp setroute

# Sets the dynamic default gateway

dhcpd auto_config outside

# DHCP deamon outside
