DHCP and Static addresses

[cjlindstrom]

I'm trying to set up an office network in a large campus environment. I can get an address via dhcp for the outside interface. I have also been assigned two static IPs that I want to use to access internal servers. I want PAT to use the DHCP address. I'm not sure how to set up the ip addresses on the external interface. I think I can do my static mappings and access lists OK.

Can this be done? If so how?

Thanks for you help.

You want to do something like this for PAT:

global (outside) 1 interface
nat (inside) 1 192.168.0.0 255.255.0.0 0 0

Does that help, or do you need more assistance with the one-to-one static mappings?

Thsnks for the help. I was trying to do it with pdm and just couldn't get it to work. I have since reconfigured it from the IOS and I think I have it working know.

Does this look right ?

access-list outside_in permit tcp any host 128.187.147.242 eq www
access-list outside_in permit tcp any host 128.187.147.243 eq www
access-list outside_in permit tcp any host 128.187.147.242 eq smtp
access-list outside_in permit tcp any host 128.187.147.242 eq pop3
access-list outside_in permit tcp any host 128.187.147.242 eq imap4
ip address outside dhcp
ip address inside 10.3.0.254 255.255.255.0
global (outside) 1 interface
nat (inside) 1 0.0.0.0 0.0.0.0 0 0
static (inside,outside) 128.187.147.242 10.3.0.1 netmask 255.255.255.255 0 0
static (inside,outside) 128.187.147.243 10.3.0.2 netmask 255.255.255.255 0 0
access-group outside_in in interface outside

I'm still working on the DNS
