IDPA-käyttöönotto epäonnistuu virheen Reverse lookup failed vuoksi

Configuring appliance network. [Step 1 of 4]Configuring Appliance Configuration Manager network. [Step 1 of 4]Appliance Configuration Manager network configuration completed. [Step 2 of 4]Network settings validation started. [Step 2 of 4]Network settings validation failed. Appliance network configuration failed. Virheen tiedot: (Huomautus: x.x.x.11 on ACM:n julkinen IP-osoite ja x.x.x.12 on ESXi:n julkinen IP-osoite) Reverse lookup failed for x.x.x.11 with primary domain name server x.x.x.240. Reverse lookup failed for x.x.x.12 with primary domain name server x.x.x.240. 


- NVT-työkalun tarkistus onnistui

- nslookup toimii oikein sekä edelleenlähetyshaussa että käänteisessä DNS-haussa

- dns-haku ACM dnsjava -apuohjelmalla epäonnistui:
