⁠Network Configuration Parameters

add address=172.20.0.3/24,172.20.0.4/24 gateway=172.20.0.1 gateway6="" name=veth2-dns

The IP addresses assigned to the interface (comma-separated). Multiple IP addresses are required if multiple routes are configured. This allows different next-hop addresses to be set for each list of domains.

Note: Multiple IP addresses are needed for configuring multiple next-hop addresses for different domain lists when using multiple routes.

⁠DNS Configuration Parameters

Below are the key-value pairs used to configure the DNS container:

KeyValue ExampleDescription
UPSTREAMdns.googleThe domain name of the upstream DNS provider (optional).
UPSTREAM_IP8.8.8.8The IP address of the upstream DNS provider (optional).
BIRD172.20.0.2IP address used for the BGP routing daemon (bgp-server).
FALLBACK_UPSTEAM1Enables fallback to secondary upstream DNS (1 = enabled).
SECOND_TUNNEL1Enables second tunnel interface (1 = enabled).
ROUTE192.168.50.1The IP address of the gateway used for routing.
ROUTE_SECOND192.168.60.1Secondary gateway IP for routing (used if multiple routes are configured).
TTL720hStorage time of the route received through the domain name (optional).

Note: Parameters marked as optional can be omitted if you are using a single route.

⁠Container Mounts

The container includes the following mount configuration:

add dst=/data name=storage src=/storage

This mount point (/data) contains two files:

  • domains.txt
  • domains_second.txt
⁠Example Domains File (.txt)
example.com
example1.com
