One for each network as you have multiple NICs?
I’ll see if I can dig up the original article, but I thought you could only have 1 default gateway specified (at least on FreeBSD)?
What does the output of “ip route” show?
Here is the ip route output - there seems to be a single default specified.
admin@storage[~]$ ip route
default via 10.0.50.2 dev enp134s0f0np0 proto static
10.0.30.0/28 dev enp7s0f1 proto kernel scope link src 10.0.30.10
10.0.50.0/29 dev enp134s0f0np0 proto kernel scope link src 10.0.50.1
10.0.60.0/29 dev enp134s0f1np1 proto kernel scope link src 10.0.60.1
10.0.100.0/24 dev eno1 proto kernel scope link src 10.0.100.101
172.17.0.0/16 dev kube-bridge proto kernel scope link src 172.17.0.1
Hm, perhaps setting this would be the culprit?
EDIT: the reason why I thought of specifying those values in Kubernetes settings is here.
