We have a client that has two ADSL routers - one is a Cisco 877 that we installed, the second has a slow 512k connection on a Cisco 837 that belongs to the client's supplier; we have no control of or access to it.
At the moment all client computers that need to access the supplier's Intranet have the supplier's router (say 10.0.0.1 for the sake of argument) set as the default gateway. This means they can access the Intranet (presumably over a VPN to the supplier - say at 172.16.0.1), but other Internet traffic is slow.
Now we can use a "ROUTE" command in Windows on the PCs to direct the traffic to the correct router - but it would be better to do this in the router, if possible.
So how do we configure the new Cisco 877 (10.0.0.90) so that if traffic comes to it that's destined to the supplier Intranet (172.16.0.1), it sends it over to the supplier router (10.0.0.1)?
Also, is it a good or bad idea to configure it this way?
Thanks in advance!
