+`eth-filter` is a translator that implements a very simple stateless firewall.
+
+
+# Source
+
+[[source_repositories/incubator]], dde
+
+
+# Usage
+
+For instance, to drop any attempt to access port 22:
+
+    # settrans -c /dev/eth0f /hurd/eth-filter -i /dev/eth0 -r "not port 22"
+
+This creates a `/dev/eth0f` device, which is the filtered version of
+`/dev/eth0`.  One can then use `/dev/eth0f` instead of `/dev/eth0`:
+
+    # settrans /servers/socket/2 /hurd/pfinet -i /dev/eth0f [...]
+
+..., or run `dhclient /dev/eth0f`, or similar.
+
+See also Zheng Da's [[user/zhengda/howto]].
