Missing a CA?

[jcarerra]

I ran the easy-rsa process in Windows.
I have resulting files among others...
ca.crt
ca.key

Server config screen in ASUS router VPN setup wants to be filled in:
Certificate Authority
Server Certificate
Server Key

Three things. I have two.

Seem to be missing the CA (not ca.crt?). What did I do wrong?

If I run "build-ca" again, will it produce another one that will be compatible with what I already have? If not, are any of the pieces still usable--or do ALL of it over again (ugh)?

in easy-rsa run build-key-server .. and Read the README file ..

Do not run build-ca again !
