Is there any way to make webkit use specific network interface

slowargo

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?
Thanks

Just figured out that the correct way is using QNetworkAccessManager:

QNetworkConfigurationManager manager;
QList<QNetworkConfiguration> listCfg = manager.allConfigurations();
foreach(const QNetworkConfiguration& now, listCfg){
	if (now.name() == strIf) {
		ui->frameWeb->page()->networkAccessManager()->setConfiguration(now);
		break;
	}
}
