I'm looking to configure a NAT router
server-------NAT Rt-------client
I need the client to think it talking to the NATRt cleint side.
And I need the server to to think the access requests are coming from the NATRt.
Effectivily each are unaware of the other subnet?
Any ideas? Any help appricaiated.
Hello,
Suppose router fa0/0(LAN) is connected to server and fa0/1(WAN) is conncted to client.
You need to do 2 NATs. Destination NAT and Source NAT.
int fa0/0
ip nat inside
int fa0/1
ip nat outside
****
Destination NAT. Client makes a request to WAN IP set on router. Client does not know the server IP
ip nat inside source static [server ip] [Wan IP on router]
***************************************
Outside Source NAT. Router changes the source of the client, so server sees the router IP instead of client IP
access-list 50 permit host [client ip]
Ip nat pool Router-IP [internal router ip for nat] [internal router ip for nat] netmask 255.x.x.x
ip nat outside source list 50 pool [Router-IP] add-route
*************************
The first NAT is easy. Please take a look at link below for the second NAT

Hope it helps

Thanks again.
You are welcome. Please give me your feedback after configuration.

Hello ,
To add on Masoud comments , With static NAT configuration in routers you achive below
ip nat outside source static :- Translates the source of the IP packets that travel outside to inside and Translates the destination of the IP packets that travel inside to outside.
ip nat inside source static :-Translates the source of IP packets that travel inside to outside and Translates the destination of the IP packets that travel outside to inside.
Hope it Helps..
