Listen Address

Test suite to validate DNS Proxy listen-address configuration. It simply configures a DNS server that may or may not block queries or even servers.

IPv4 Address

Description

DUT0 is configured on a specific IPv4 address and checked by the local resolver to see if it works as expected.

Scenario

Step 1: Set the following configuration in DUT0:

set system certificate trust running://remote.dns-server.crt
set service dns proxy server-name RD
set service dns proxy static RD protocol dns-over-https host name remote.dns
set service dns proxy static RD protocol dns-over-https ip 10.215.168.1
set service dns proxy static RD protocol dns-over-https hash ec4467518bda940b10464a7630c570e7717035cc032e5ae3bec7c4f937f00d8e
set service dns proxy listen-address 10.215.168.64 port 53
set service dns resolver name-server 10.215.168.64

Step 2: Run command show host lookup teldat.com type A at DUT0 and check if output contains the following tokens:

teldat.com has address 19.18.17.16
Show output
teldat.com has address 19.18.17.16

IPv4 Address With Port Changed

Description

DUT0 is configured on a specific IPv4 address and a different port, then checked by the local resolver to see if it works properly.

Scenario

Step 1: Set the following configuration in DUT0:

set system certificate trust running://remote.dns-server.crt
set service dns proxy server-name RD
set service dns proxy static RD protocol dns-over-https host name remote.dns
set service dns proxy static RD protocol dns-over-https ip 10.215.168.1
set service dns proxy static RD protocol dns-over-https hash ec4467518bda940b10464a7630c570e7717035cc032e5ae3bec7c4f937f00d8e
set service dns proxy listen-address 10.215.168.64 port 5353
set service dns resolver local
set service dns forwarding name-server 10.215.168.64 port 5353

Step 2: Run command show host lookup teldat.com type A at DUT0 and check if output contains the following tokens:

teldat.com has address 19.18.17.16
Show output
teldat.com has address 19.18.17.16

IPv6 Address

Description

DUT0 is configured on a specific IPv6 address and then checked by the local resolver to see if it works properly.

Scenario

Step 1: Set the following configuration in DUT0:

set interfaces ethernet eth1 address 10::2/64

Step 2: Ping IP address 10::2 from DUT0:

admin@DUT0$ ping 10::2 count 1 size 56 timeout 1
Show output
PING 10::2(10::2) 56 data bytes
64 bytes from 10::2: icmp_seq=1 ttl=64 time=0.017 ms

--- 10::2 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.017/0.017/0.017/0.000 ms

Step 3: Set the following configuration in DUT0:

set system certificate trust running://remote.dns-server.crt
set service dns proxy server-name RD
set service dns proxy static RD protocol dns-over-https host name remote.dns
set service dns proxy static RD protocol dns-over-https ip 10.215.168.1
set service dns proxy static RD protocol dns-over-https hash ec4467518bda940b10464a7630c570e7717035cc032e5ae3bec7c4f937f00d8e
set service dns proxy listen-address 10::2 port 53
set service dns resolver name-server 10::2

Step 4: Run command show host lookup teldat.com type A at DUT0 and check if output contains the following tokens:

teldat.com has address 19.18.17.16
Show output
teldat.com has address 19.18.17.16

IPv6 Address With Port Changed

Description

DUT0 is configured on a specific IPv6 address and a different port and then checked by the local resolver to see if it works properly.

Scenario

Step 1: Set the following configuration in DUT0:

Show output
PING 10::2(10::2) 56 data bytes
64 bytes from 10::2: icmp_seq=1 ttl=64 time=0.021 ms

--- 10::2 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.021/0.021/0.021/0.000 ms

Step 3: Set the following configuration in DUT0:

set service dns proxy listen-address 10::2 port 5353
set service dns resolver local
set service dns forwarding name-server 10::2 port 5353

Step 4: Run command show host lookup teldat.com type A at DUT0 and check if output contains the following tokens:
