Static NATing between Private addresses..

Unanswered Question
Mar 23rd, 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 (existing network) and, which will allow me to route and use the existing network without having to reip the site.

for example map -> etc..

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

I have this problem too.

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

ip nat inside source static

ip nat inside source static


then on your router

int fa0/0

ip address

ip nat inside

int fa0/1

ip nat outside

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


ip nat inside source static tcp 80 80 extendable

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

Thanks for your reply...
