I have 5 public, static ip addresses leased plus 3 more reserved. The
range is:

63.x.x.n (reserved network)
63.x.x.n+1 (user assignable)
63.x.x.n+2 (user assignable)
63.x.x.n+3 (user assignable)
63.x.x.n+4 (user assignable)
63.x.x.n+5 (user assignable)
63.x.x.n+6 (reserved gateway)
63.x.x.n+7 (reserved broadcast)

I have an internal network running on 192.168.0.x that has 2
webservers that the public internet needs to get to. When I had my
Cisco 675, I simply enabled NAT and added NAT entries as follows:

set nat add entry 63.x.x.n+1 80 192.168.0.2 80 tcp
set nat add entry 63.x.x.n+2 80 192.168.0.3 80 tcp

now any public HTTP traffic for 63.x.x.n+1 would go to my internal
webserver @ 192.168.0.2 and HTTP traffic for 63.x.x.n+2 would go to
192.168.0.3.

This procedure does not work on my Cisco 678. Will someone please let
me know what I have to do in order to utilize my 5 public static IP
addresses again? When I say "does not work" I mean the
http://www.mydomain.com which is associated to 63.x.x.n+1 is not
accessible via the public internet. I have verified that the webserver
is functioning internally at http://localhost. Note:
http://www.mydomain2.com goes to 63.x.x.n+2 although this is not
configured yet. I do not want to give my webservers the public static
IPs, I want to use NAT to forward the public static ips to internal
static IPs.

Here is some diagnostic info off the 678:

cbos#sho nat

NAT is currently enabled

Port Network Global
eth0 Inside
wan0-0 Outside 63.x.x.n #reserved gateway IP
vip0 Outside
vip1 Outside
vip2 Outside

Local IP : Port Global IP : Port Timer Flags Proto Interface

## where eth0 is Inside and using 192.168.0.1

cbos#sho int

vip1 0.0.0.0 255.255.255.0

vip2 0.0.0.0 255.255.255.0

wan0 Physical Port: Trained

Dest IP Address Mask
wan0-0 207.x.x.x 255.255.255.255 # configured via IPCP

Any help would be greatly appreciated!

Thanks in advance,
