Is there any way to make webkit use specific network interface

  • Hi all,
    I'm trying QT5 on a linux box which has multple network interfaces. I would like to use webkit to show the wifi web portal and therefore the traffic of webkit should only go through wlan instead of any other interfaces. I came up with two ideas:
    1 use iptables to redirect all packets with port 80 to wlan
    2 make wlan the default gateway
    But both of them may affect existing connections. I'm wondering is there a better way to bind webkit's sockets to the specified network interface?

  • Just figured out that the correct way is using QNetworkAccessManager:

    QNetworkConfigurationManager manager;
    QList<QNetworkConfiguration> listCfg = manager.allConfigurations();
    foreach(const QNetworkConfiguration& now, listCfg){
    	if ( == strIf) {
