+The default arguments configuration runs the crawler with DHT and UPnP forwarding disabled, but the current `librqbit` implementation still handles PEX connections. Use the following tips to enhance your privacy, in addition to the firewall rules.
+
+## The P2P Blocklist
+
+Use the P2P Blocklist argument to filter **outgoing** connections:
+
+``` bash
+aquatic-crawler --blocklist=file:///path/to/blocklist.txt
+```
+or
+``` bash
+aquatic-crawler --blocklist=http://domain.to/blocklist.txt
+```
+
+### Examples
+
+To block Internet connections (restrict outgoing requests to local network peers only)
+``` blocklist.txt
+Internet IPv4:0.0.0.0/0
+Internet IPv6:2000::/7
+```
