Cisco 2811 Router - Setup second external IP or not

I have a 2811 that is setup with an external IP, this has access lists and firewalling turned on. I need to setup OWA (SSL) through it to point to an internal server. I am wondering whether it is best to setup a second external IP or not necessary.

The internal server is at 192.xxx.xxx.100

The secondary external IP if needed is xxx.xxx.xxx.131

The existing config for the external port is:

interface FastEthernet0/0

description To ISP-INTERNET

ip address xxx.xxx.xxx.130 255.255.255.248

ip access-group 120 in

ip nat outside

ip inspect FIREWALL out

ip virtual-reassembly

duplex auto

speed auto

crypto map To-HQ

!

interface FastEthernet0/0.101

!

you needn't use a secondary ip for this.

Just do static NAT or static PAT.

ip nat inside source static 192.xxx.xxx.100 xxx.xxx.xxx.131

ip nat inside source static tcp 192.xxx.xxx.100 443 xxx.xxx.xxx.131 443
