This is my take at the FreeBSD 11 network configuration on fail-over IPs. Append the following to
/etc/rc.conf. In my example
em0 is the network interface (use
ifconfig to confirm),
184.108.40.206 is the VMs IP-address and
220.127.116.11 is the ESXi host.
ifconfig_em0="inet 18.104.22.168 netmask 255.255.255.255 broadcast 22.214.171.124" static_routes="em0_iface" routes_em_iface="-net 126.96.36.199 -iface em0" defaultrouter="188.8.131.52"
We configure DNS resolving using the OVH DNS server
184.108.40.206 by creating
/etc/nslookup.conf with the following contents:
If you lose connectivity after a while check your
dmesg for ARP entries changes mac-address (especially your ESXi host/gateway). If this happens you can create
It might not be the most OS-native way, if you have improvements please let me know.
