Network sharing---Proxy?

hi guys,

I need to develop an application to allow two PCs share Internet Access. The
scenario is followed:

Internet <----> PC A<---> PC B


Desktop B connects to Desktop A with ethernet cable. A has a dialup
connection to Internet. Now B will surf the net through A. I know a proxy
will do the job, but a proxy is over Transport layer, not IP layer. So A
needs to monitor all possible ports(like 80, 21, etc) to redirect internet
data. Is it possible for A to monitor all data in the IP layer so A can just
act like a router? Does windows provide such functionalities?


Thanks,

Oscar

Hi Oscar,

Yes, you can use Windows as a router. You can e.g. setup Windows XP as a
router (ICS -- Internet Connection Sharing)

Same goes for server editions...

Next thing you can look for is information on RRAS (Routing and Remote
Access Server).

hi Miha,

Thank you for your reply. The problem I have right now is: the PC working as
a router/gateway runs windows CE 2003. Moreover, I am trying to write code
to implement this function, other than using MS' configurations. DO you have
any idea about this?

Thanks,

Oscar

Hi Oscar,

Sorry :-\, I am not familiar nor with Windows CE nor with development
tasks...

My advice would be to check with developer groups...
