Question : Configure Cisco ASA 5510 with additional IP address

We have a Cisco ASA 5510 that was installed and configured by an old admin. We have a block of 8 IP addresses that are assigned to this connection and the Cisco is currenty configured to use one of these.

The Cisco is currently configured to allow ports 25, 80 and 443 to the mail server for incoming e-mail and OWA access. We now have an SSL-VPN device and would like to use the next IP address in our external range for this. Can you advise what I need to do through the ASDM configuration utility to allow the ASA 5510 to use the additional IP address and pass ports 80 and 443 to the required internal IP address?
