Hello Everyone,

I've two Cisco ASA 5550 firewall. I'm don't have much knowlege on configuring this kind of firewall. I need help on configuring these firewall for simple NAT. I have 3 public IP address. I would like to allow server's inside of the firewall to be able to connect to internet using private address. A basic NAT. Also need to configure some port forwarding. We've bought two firewall for the Active/Active failover support. How can i configure this through ASDM? My ASDM version is 5.2.

I would be greatful if you please help me on this. Thanks in advance.

Regards,

Saif
