Greetings and thank you in advance for your help ,

my setup is just like this

computer 1

windows 8.1 with one interface configured like the following

ipv4  : 172.19.209.130

mask : 255.255.255.252

default GW : 172.19.209.129

connection has no internet available .

computer 2

windows server 2012 R2 with two interfaces

interface 1 configured as following

ipv4  : 172.19.209.129

mask : 255.255.255.252

default GW : 172.19.209.130

connection has no internet available .

interface 2 configured as following

ipv4  : 192.168.7.66

mask : 255.255.254.0

default GW : 192.168.7.1

connection has internet available .

i have been struggeling to give computer 1 internet throught bridging computer 2 connections with no success ..

so what i am looking for is to have internet on computer 1 through it's connection with computer's 2 first conenction which is somehow bridged to the internet capable interface ..

any help would be appreciated .

What you are trying to do is route traffic. Different from bridging. In order for Computer 1 to use the internet connection on Computer 2, Computer 2 has to have some type of routing software installed.  Windows Server comes with a feature known as RRAS.  Install and configure it and you will have what you want.

Hello again and thank you for the fast reply ,

i have added the router role to my server , configured it , but still the client cant access internet ..

configuring NATing is pretty simple with the wizard , any special configurations to be done on the client ? (computer 1 )

thanks again

Standard IP configuration.  Your client needs to point to the RRAS server as its default gateway and the client's DNS entry must be able to resolve internet DNS names.

Thank you again for your precious input ,

kindly note that testing with an identical setup but using a network cable to the second interface of the NATing computer DID WORK , i managed to give internet to a computer that only have one connection with no internet through NATing the very same connection from the other end with an internet capabl connection ..

that raise the question , any way the Data Solution company ( which sells 3G Sims as well ) has blocked Nating for internet of thoses sims to force clients to get normal 3Gs ?

noting that the internet conenctionm netmask is 255.255.254.0 and the data solution subnet mask is 255.255.255.252

any Issues related to the diffirence between netmasks may raise to the surfac e?
