NAT and Routing

[husseinmuneer]

Dear Sirs,

as shown in the attached diagram, the laptob user want to use an application in the server but the user shoud pass all the routers between him and the server (R1,R2,R3) so what is the additional configuration should we add to make him able to access the server and use the TCP ports 5500-5530?

Note: we can ping from R1 to server.

Thanks in advance for you help.

Regards

Hello,

You need to add the following configuration on R1:

ip nat inside source static 192.168.0.202  interface dialer0 overload

interface f0/0

ip nat inside

interface dialer0

ip nat outside

You should also change the config of R2 as follows:

Change the Default route from 10.10.10.1 to 192.168.93.200:

no ip route 0.0.0.0 0.0.0.0 10.10.10.1

and Add the following route on R2:

ip route 192.168.0.0 255.255.255.0 10.10.10.1

You Should also add the following on R3:

ip route 0.0.0.0 0.0.0.0 10.10.10.2
