ASDM through firewall access

Probably a strange request, but maybe not. I have two ASA 5520's, one behind the other as one is IPS the other CSC. I need to setup ASDM access through the IPS firewall to the second firewall for external management. I have SSH setup already sharing an external IP address with the CSC and AIP modules, but I cant access the https portion of the second firewall. Are there other ports besides 443 I need to open up for the external IP? To rule out ACL I have permit IP any to the IP.

Re: ASDM through firewall access

The first firewall, outside interface with lower security level to inside interface with higer security should static nat map to the second firewall's outside interface IP.

Otherwise, no-nat on first firewall allows traffic to pass from the outside to the inside without translating the source addresses.
