"Network is unreachable" error - Gentoo, silly netifrc configuration mistake

So on a new install I was just sitting there and wondering .. what did I do wrong .. why do I keep getting those errors:

# ping lordvan.com
connect: Network is unreachable

then I realized something when checking the output of route -n:

 # route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.0.0     0.0.0.0         255.255.255.0   U     0      0        0 enp96s0f0
192.168.0.254   0.0.0.0         255.255.255.255 UH    2      0        0 enp96s0f0

It should be:

 # route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         192.168.0.254   0.0.0.0         UG    2      0        0 enp96s0f0
192.168.0.0     0.0.0.0         255.255.255.0   U     0      0        0 enp96s0f0

Turns out I had forgotten something quite simple, yet important: add "default via <router IP>" to /etc/conf.d/net.. So after changing it from

routes_enp96s0f0="192.168.0.254"

to

routes_enp96s0f0="default via 192.168.0.254"

and restarting the interface everything works just fine ;)

Silly mistake, easy fix .. can be a pain to realize what went wrong though .. maybe someone will make the same mistake and find this blog post hopefully to fix it faster than me ;)
