Olá srs. Estou com duvidas na configuração do meu serviço dhcpd, o serviço não roda e apresenta os logs: Logs de erro: Jul 28 18:50:29 FW-01 dhcpd: No subnet declaration for eth1:0 (no IPv4 addresses). Jul 28 18:50:29 FW-01 dhcpd: ** Ignoring requests on eth1:0. If this is not what Jul 28 18:50:29 FW-01 dhcpd: you want, please write a subnet declaration Jul 28 18:50:29 FW-01 dhcpd: in your dhcpd.conf file for the network segment Jul 28 18:50:29 FW-01 dhcpd: to which interface eth1:0 is attached. ** Jul 28 18:50:29 FW-01 dhcpd: Jul 28 18:50:29 FW-01 dhcpd: Jul 28 18:50:29 FW-01 dhcpd: Not configured to listen on any interfaces!
Seguem abaixo as configurações de meu ambiente. PS : O servidor é um firewall que possui diversas rotas staticas para redes distintas.
