### `Swarm.EnableHolePunching`

Enable hole punching for NAT traversal
when port forwarding is not possible.

When enabled, go-ipfs will coordinate with the counterparty using
a [relayed connection](https://github.com/libp2p/specs/blob/master/relay/circuit-v2.md),
to [upgrade to a direct connection](https://github.com/libp2p/specs/blob/master/relay/DCUtR.md)
through a NAT/firewall whenever possible.
This feature requires `Swarm.RelayClient.Enabled` set to `true`.

Default: `false`

### `Swarm.EnableAutoRelay`

Deprecated: Set `Swarm.RelayClient.Enabled` to `true`.
