asa 5510 multiple sequential IP addresses on external NIC

Hi there,

i was wondering if it was possibly (using 5510 with security plus pack for gig ports) to have multiple public IP addresses (up to 4 IP addresses) on the external NIC/s of the asa.

thee IP addresses would not be on different subnets. they would be a collection of 4 sequential address in the same class/subnet.

I believe it may be possibly through using the same-security-traffic permit intra-interface command and then mapping VLANS to VLAN setup on switch with VLAN features.

I know the ASA is not a router but Im hoping it amy allow for the end goal - which is to have different services running on different IP addresses i.e. SMTP service running on one IP (for both basic IP lockdown to SMTP provider and future migration purposes - allows the IP to be removed with impact to other service running through the ASA. The VPN services running on 1 IP (locked down) and SSL VPN OWA to run on another port.

Is there any disadvantages in using this framework.

Thanks in advance for your time and help.

Kind regards
