Hello,
I'm trying to configure a basic router with carp enabled (as describe in the
OpenBSD manual).
My server has one primary interface (vio0) with an IP used to access it
directly (whatever the CARP interface status is): 10.0.11.1/16
It provides a shared interface on carp0 with the IP: 10.0.10.1/16
I want to set the default route on the carp iface, so the public IP when
connecting a remote host is the carp IP.
The problem is when I do that, the system completely ignore the default route
and always return a "no route to host" error when I try to access the
network.
My config is as follow:
---- ifconfig
