## IP addresses and ports to listen to, as well as their external IP
## If there is no NAT involved, `local` and `external` can be the same.
## As many addresses as needed can be configured here, IPv4 and/or IPv6.
## You should at least change the `external` IP address.

### Example with both IPv4 and IPv6 addresses:
# listen_addrs = [
#     { local = "0.0.0.0:443",    external = "198.51.100.1:443" },
#     { local = "[::]:443",       external = "[2001:db8::1]:443" }
# ]

listen_addrs = [
    { local = "0.0.0.0:8443",    external = "**YourIP**:8443" },
    { local = "[::]:8443", external = "[**YourIP**]:8443" }
]

## Optional IP address to connect to upstream servers from.
## Leave commented/undefined to automatically select it.

# external_addr = "0.0.0.0"


## Built-in DNS cache capacity

cache_capacity = 100000


## DNS cache: minimum TTL

cache_ttl_min = 3600


## DNS cache: max TTL

cache_ttl_max = 86400


## DNS cache: error TTL

cache_ttl_error = 600


## DNS cache: to avoid bursts of traffic for popular queries when an
## RRSET expires, hold a TTL received from an upstream server for
## `client_ttl_holdon` seconds before decreasing it in client responses.

## Run as a background process

## Log file

# log_file = "/tmp/encrypted-dns.log"

## User name to drop privileges to, when started as root.

## Group name to drop privileges to, when started as root.

group = "DNSCrypt"


## Path to chroot() to, when started as root.
## The path to the state file is relative to the chroot base.

# chroot = "/var/empty"


## Queries sent to that name will return the client IP address.
## This can be very useful for debugging, or to check that relaying works.
