change pref src for route

[SlipKo]

Hello!

I have VM with FreeBSD 12.2. vtnet0 has grey ip address from 10.0.0.0/8 and lo0 has white ip address from 92.xxx.yyy.0/24. I want to set default gw via vtnet0 with pref src address of lo0. How I can do it?

Grey, white? What is that supposed to mean?

I want to set default gw via vtnet0 with pref src address of lo0.

That's not how TCP/IP works.

Grey addresses from RFC1918. White addesses are routed to Internet.

But in Linux I can set default route with pref src setting: ip r add default via gw src <loopback ip address> and it works correctly.

The common terminology is "private" (RCFC1918) and "public" (for internet-routable) ip addresses.
