Im trying to replace a checkpoint NG AI Firewall thats securing a web hosting farm with several internal web servers running about 25 web sites.. I wan to replace the Checkpoint with a Cisco ASA 5520, running OS 8. One of the key implementations on the checkpoint that I need to replicate is a port redirection thats in place for all the web sites.. Which maps from a public IP to an internal IP and a different host.. i.e.
On the checkpoint side in destination field there is
static NAT to Y public IP.
static NAT to Q public IP.
static NAT to K public IP.
And so on for all the web sites..
On the service field there is a custom built service which has a match i.e. under advanced that has this&
And so on for all the web sites, for both https and http..
I assumed its a simple case of doing a PAT, so on the ASA I setup a static NAT where I put in the public IP on the original source field and on the translated to section inside interface and inside IP and enable PAT and put in the source and destination ports as above.. I also added the usual allow any traffic from any where to the public IP on the outside interface Access list&
All this does not seem to work on the ASA, works fine on the Checkpoint, Im sure Ive got it totally wrong & Any idea ??
