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

The secondary external IP if needed is

The existing config for the external port is:

interface FastEthernet0/0

description To ISP-INTERNET

ip address

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

ip nat inside source static tcp 443 443
