The PC connected to the DHCP server cannot obtain DNS information when the AR1220 serves as the PPPoE client

The AR used as the DHCP server cannot assign information about the DNS server obtained from the PPPoE server to DHCP clients.
1. Run the ppp ipcp dns admit-any command on the dialer interface to configure the AR to receive the IP address of the DNS server specified by the remote device. If the command is not configured, the AR cannot obtain DNS information.
2. DNS proxy is used to meet customers' requirements. Run the following commands in the system view:
dns resolve
dns proxy enable
In the IP pool view, dns-list is configured as the address of the AR.
In this way, the AR is equivalent to the DNS server for a PC. After receiving a DNS request, the AR sends it to the DNS server to complete domain name resolution.
