Describe the Bug
I am using Nebula to assign a public IPv4 to a host behind NAT. Everything works well, except I cannot add a default route to an arbitrary routing table. When I do, Nebula crashes.
To reproduce, while you have Nebula running, run
ip route add default via <nebula-peer-gateway> table 1011
You can use any route table number or name, make a number up if you wish.
In effect, I'm not overriding my default route on my host. I want policy based routing to respond back using a specific routing table, and thus the need of a default route.
If I add all the CIDRs of public IPs to a given table, instead of using 'default', my policy based routing works. As in:
ip route add 23.x.y.0/24 dev nebula1 proto kernel scope link src 23.x.y.30 mtu 1300 table nb4n0
/sbin/ip rule add from 23.x.y.30 table nb4n0
