Hi Peter, You was right! I append the -Djava.net.preferIPv4Stack=true option in the project file:
(defproject clj-echo-server "0.1.0-SNAPSHOT" :description "Echo server with Aleph" :url "http://example.com/FIXME"; :license {:name "Eclipse Public License" :url "http://www.eclipse.org/legal/epl-v10.html"} :dependencies [[org.clojure/clojure "1.4.0"] [aleph "0.3.0-beta12"]] :main clj-echo-server.core *:jvm-opts** ["**-Djava.net.preferIPv4Stack=tru**e**"]*) And now works in the way I want. Thanks!
