Upnp not forwarding port

Two routers is quite a tricky setup. The message 'accepts incoming connections from contacted addresses.' indicates that the port is not fully opened, but only accepts incoming connections from addresses that have been contacted before. Did you setup port-forwarding on both routers?

Hi Kevin, sorry for not coming back to you earlier. If you'd like to have a look at the upnp code, just download the SBBI UPNP library (http://www.sbbi.net/site/upnp/). We're accessing it in the following method:

private boolean setupRouter(int localPort) {
try {
Logging.getLogger().info("Trying to configure connection using UPnP");
InternetGatewayDevice[] IGDs = InternetGatewayDevice.getDevices(UPNP_DISCOVERY_TIMEOUT);
if (IGDs == null) {
Logging.getLogger().info("No Internet Gateway Device found");
return false;
} else {
Logging.getLogger().info("Found " + IGDs.length + " UPnP routers");
boolean mapped = false;
for (int i = 0; i < IGDs.length; i++) {
InternetGatewayDevice igd = IGDs[i];
try {
if (igd.getSpecificPortMappingEntry(null, localPort, "UDP") != null){
igd.deletePortMapping(null, localPort, "UDP");
}
} catch (IOException e){
//ignore
} catch (UPNPResponseException e ){
//ignore
}
mapped |= igd.addPortMapping("Wuala UPnP", null, localPort, localPort, getInternalAddress(), 0, "UDP");
Logging.getLogger().info("Could add port mapping on device " + igd.toString() + ": " + mapped);
}
return mapped;
}
} catch (IOException e) {
return false;
} catch (UPNPResponseException e) {
return false;
} catch (Throwable e){
return false;
}
}

public String getInternalAddress() throws IOException{
Enumeration<networkinterface> ifaces = NetworkInterface.getNetworkInterfaces();
while (ifaces.hasMoreElements()){
Enumeration<inetaddress> addrs = ifaces.nextElement().getInetAddresses();
while (addrs.hasMoreElements()){
InetAddress addr = addrs.nextElement();
if (addr instanceof Inet4Address && !addr.isLoopbackAddress() && !addr.isAnyLocalAddress() && !addr.isLinkLocalAddress() && !addr.isMulticastAddress()){
return addr.getHostAddress();
}
}
}
throw new IOException("No valid local internet address found");
}
</inetaddress></networkinterface>
