What are you trying to achieve with that setup? In the general case, you
wouldn't do that.

If server has an address on 192.168.1.0/24, then it has a "connected" route
automatically created by the OS, and that will be preferred over other
routes. No change required.

If the server is not directly connected to 192.168.1.0/24, then you will
need a static route to get to it. The gateway for that route will be an IP
address on a subnet that both the server and the router have an address on.
The router will also have an address on 192.168.1.0/24.


For (ii) you set the default route out that interface.

The LiveDVD is a user contribution by Fernando Reyes, coordinated with
RelEng to some extent. Usually updated in time of some conference event
with bigger Gentoo presence to hand out pressed DVDs with some artwork.

You can catch him as "likewhoa" nickname in the #gentoo-ten IRC
channel.

Have a look at the Release Engineering project:

https://wiki.gentoo.org/wiki/Project:RelEng

The project email address, IRC channel and list of members can be seen on the 
right hand side of the page.

I'm sure they would welcome contributions and will be able to advise on due 
process.

Hello everyone,

I noticed that the Gentoo livedvd is outdated. Is anyone assigned there
to contact? I would like to updated it, since I use it very often.

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.

Did you also have zbud enabled at the time?
