I have a little problem and it's the next one. Hire a debit vps service and two dominos with the same provider. install bind9 as dns server, configure the named.conf.local zones, create the respective files db.nombre.com and db. (ip) which is the reverse zone. then restart the bind9. and everything perfect. I make host ns1.domain.com ns2.domain.com / dig @server ns1.domain.com and all fine I ping ns1.domain.com ns2.domain.com and if I ping it I see that everything is fine. but then I ping from any local computer with ip or name ns1.domain.com or ns2.domain.com and do nothing. Only the local team reflects me doing the command dig @servidor ns1.dominio.com. only that. My question is how can you make ns1.domain.com ping from any external device. since I need it to be able to register my new dns to the provider's panel. who can clear me of doubts. thank you very much
