I have router which have "adapter1" for NAT, "adapter2"for intnet1, and "adapter3" for intnet2. I made connection with router, web, and desktop by giving enp0s8 for "adaptor 2" (I changed those at the /etc/netplan/. It worked when I test a ping. But, I wonder how to do with adapter 3. The I give enp0s3 for adapter 1, and enp0s8 for adapter 2. Should I make another enp0s? or what can I do to make connection between the router and web?
