Re: New to RASS for Routing

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

You do not need any routes at all on the router. And you do not need any
default gateway settings on the router. You only need a default gateway on a
router if it needs to forward traffic to another router. With a proxy
service, the client has the IP address of the proxy server coded in, so it
does not need to using default routing to find it.

What is essential is that the proxy server knows how to reach the client
to return the information it obtains from the Internet.

So the RRAS server just needs to be enabled as a LAN router. It should
have no default gateways set on either NIC. Set the clients in your test LAN
to use the RRAS server as their default gateway.

Where you do need to make changes is at the proxy server. You need to
add your new subnet as part of the LAT (ie the proxy server must know that
this subnet is local). And the proxy server needs to know that it can reach
the new subnet through your RRAS router.

Existing network
|
company LAN
RRAS
192.168.18.10 dg blank
|
192.168.18.x dg 192.168.18.10

Requests to the proxy will reach it without any extra routing added. All
you need is extra routing on the proxy server to get replies back to the
client.
