Point subdomain to other ip server from sentora

[Ron-e]

but in your pictures i see the domain sentora.ga in the same module as subdomains you add , i understand this subdomains must be add as domains in the second server and after this create dns for works

Nope it's a domain which is almost similar to the domain Sentora.ga.

This step don´t understand many because in your images i see 3 domains in the first server - i understand it´s the first server because i see sentora.ga also -

Nope it's the second server / VPS, again it's a almost similar domainname.
