Users on an Internal Network Cannot Access Internal Servers Using Domain Names. Why?
When a user device accesses the internal server using a domain
name, whether the domain name contains the host name varies. Therefore,
you have to configure different DNS domain names in the following
two situations. For example, you want to access the domain name www.hbjs.gov.cn.
- When the DNS Request packet sent by the user device contains the host name, that is, the user device uses the domain name www.hbjs.gov.cn to access the internal server, run the nat dns-map www.hbjs.gov.cn global-address global-port { tcp | udp } command.
- When the DNS Request packet sent by the user device does not contain the host name, that is, the user device uses the domain name hbjs.gov.cn to access the internal server, run the nat dns-map hbjs.gov.cn global-address global-port { tcp | udp } command.
If you are not sure whether the DNS Request packet sent by the device contains the host name or not, it is recommended that you configure both the preceding commands.
