C1 can (and should IMO) just have a direct route to 50.50.50.51. > Then C2 will be configured to forward packets to 50.50.50.51 when it > receives packets on its interface with 192.168.1.3. Huh ? What do you mean ? C2 owns 50.50.50.51, there is no point in forwarding packets with a local destination address. And what does 192.168.1.3 have to do here ? We are *NOT* talking about NAT here, are we ? Just plain IP forwarding ? > In the outgoing direction: > C2 will be configured with a default gateway of 192.168.1.2 (C1), and > be configured to put source address 50.50.50.51 in its packets. > C1 will be configured with a default gateway of 192.168.1.1. > Home-router will be configured with a default gateway of the ISP- > router. Ok. One problem could be that C1 may send ICMP Redirect messages to C2 advertising that there is a shorter route using directly 192.168.1.1 as the next hop. So you may want to disable sending such messages on C1 or accepting them on C2. See /proc/sys/net/ipv4/conf/<interface>/*redirects > Resulting in a network setup like this: > > C2 > C1 192.168.1.3 > 192.168.1.2 50.50.50.51 > | | > ----------------------- > | switch | > ----------------------- > | > 192.168.1.1 > Home-router > 50.50.50.50 > | > ISP-router > > Is this the easiest/best/most standard way of setting up the network, > given that NAT should not be used for C2? Yes. Now it all relies on the capability of the router to properly forward traffic to and from 50.50.50.51, without adding any NAT.
