Static NATing between Private addresses..

osmansmalik · ‎03-23-2009

i'd like to convert one of our new sites to the network without re-ipping the site to fit our subnets. Can i do some static natting between 192.168.1.0/24 (existing network) and 10.248.108.0/24, which will allow me to route and use the existing 192.168.1.0/24 network without having to reip the site.

for example map 192.168.1.40 ->10.248.108.40 etc..

Any help with a sample config or a link to website with info will be appreciated...

Do you mean static or dynamic. Assuming you meant static then it is relatively trivial eg.

ip nat inside source static 192.168.1.40 10.248.108.40

ip nat inside source static 192.168.1.41 10.248.108.41

etc...

then on your router

int fa0/0

ip address 192.168.1.1 255.255.255.0

ip nat inside

int fa0/1

ip nat outside

John,

Actually i am trying to do Static Nat and dynamic as well at the same time. Although it is trivial but i think thats the only option i have.

How will it work if i have a webserver.

will i be able to do port forwarding with static nat which means i will require 2 static nat statements.

One to map to the 10.248.108 ip and another to the WAN ip.

ip nat inside source static 192.168.1.40 10.248.108.40

and

ip nat inside source static tcp 192.168.1.40 80 67.12.88.96 80 extendable

Also will i be able to do port overload (PAT) at the same time for clients on 192.168.1.41 accessing the internet.

Thanks for your reply...
