How to add a default route to a DHCP-enabled interface?
All my servers' networking is configured via DHCP which sends, among others, a static route (needed for a VPN) and a gateway. This works fine.
I have one exception: a server which should not get the static route (but get everything else, ideally the gateway as well).
In order to deny the provided route(s), I added to its network config
[DHCP]
UseRoutes=false
This got rid of the static route (good) and also the default gateway (not good).
Ideally, I would like to receive the gateway from the DHCP server but I am OK to hardcode it in the configuration.
To this I tried several solutions, all of them failed (= the default route was not added)
- Add a
Gateway=entry in the[Network]section:
[Match]
Name=br0
[Network]
DHCP=yes
Gateway=192.168.10.1
[DHCP]
UseRoutes=false
- Add an extra route, with something which looks like a "default":
[Match]
Name=br0
[Network]
DHCP=yes
[DHCP]
UseRoutes=false
[Route]
Gateway=192.168.10.1
Destination=default
# or, alternatively
# Destination=0.0.0.0/0
How can I add a default route to a DHCP configuration which denies the provided routes?
In other words, how to make systemd-networkd run something equivalent to ip r add default via 192.168.10.1?
