I have two questions: 1. Is it feasible to have both Ethernets connect, directly or indirectly, to the same DSL modem/router? (Adam seemed to imply that he operates this way). The device is a Billion Bipac 8900AX R2, which can segregate LAN ports, but as far as I can see it can't assign different IP addresses to them. 2. How should I set up routing on the web server so that outgoing traffic from itself is routed as follows: (i) if the destination is in the 192.168.1.0/24 subnet, the packet should go out through enp2s0, and (ii) traffic to all other destinations goes out through enp1s0? There ought to be a simple addition to /etc/conf.d/net, but I can't see what, even after looking through several web resources, including these: https://wiki.gentoo.org/wiki/Handbook:AMD64/Networking/Introduction et seq https://wiki.gentoo.org/wiki/Static_Routing. -- Regards Peter
