General questions

HI Guys

Will Vyos work on a single NIC and using alias IPs or do I need to have 2 NICs ?

Thanks
Kitty

I guess it depends on what you want to use VyOS for.

As a router.

I don’t know if you can properly NAT using only IP Aliases. I would have to try and wrap my head around the logistics of that. You can very easily use VLANs to do so, but I don’t know if aliases will work right.
