Description bugs.freedesktop.org 2015-01-29 09:11:04 UTC 
I have a machine that has multiple outgoing IP -addresses (one of which is a Keepalived VIP) and I want to force outgoing traffic to use a certain IP. This is what I thought would be the best solution:

[Match]
Name=eth0

[Network]
DNS=xxx
DNS=xxx
Address=a.b.c.d/24
Address=a:b:c/64
Gateway=a:b

[Route]
Destination=0.0.0.0/0
Gateway=a.b.c.d
Source=a.b.c.d/32

However; it doesn't work. `ip route` still shows "default via a.b.c.d dev eth0" without a source IP. If I manually execute `ip route add default via a.b.c.d dev eth0 proto static ` it works fine

How can I modify the default route in a .network file?

Is there anything you need from me to help? Is there a workaround I should be using, or is this simply not supported?
Comment 2 Timo R. 2015-05-29 19:35:21 UTC 
I'm also affected by this, has this ever been fixed in some systemd version?
Comment 3 Lennart Poettering 2019-03-19 12:26:58 UTC 
I am pretty sure this has been fixed in current systemd versions. If this is reproducible on the two most current systemd versions (240 or 241) please file a new issue on systemd github. Thank you.
