Enable/Disable Firewall

Enable/Disable Firewall

Please follow below steps to Enable/Disable Firewall

1. Implement initialization callback and get the DataFactory instances

Optionally initialization callback can be provided with get manager instance. Data factory will call callback when manager initialization is complete.

auto initCb = [&](telux::common::ServiceStatus status) {
   std::lock_guard<std::mutex> lock(mtx);
   status_ = status;
   initCv.notify_all();
};
auto &dataFactory = telux::data::DataFactory::getInstance();

2. Get the FirewallManager instances

std::unique_lock<std::mutex> lck(mtx);
auto dataFwMgr  = dataFactory.getFirewallManager(opType, initCb);

3. Wait for FirewallManager initialization to be complete

initCv.wait(lck);

3.1 Check FirewallManager initialization state

If FirewallManager initialization failed, new initialization attempt can be accomplished by calling step 2. If FirewallManager initialization succeed, proceed to step 4

if (status_ == telux::common::ServiceStatus::SERVICE_AVAILABLE) {
   // Go to step 4
}
else {
   //Go to step 2 for another initialization attempt
}

4. Implement callback for setting firewall

auto respCb = [](telux::common::ErrorCode error) {
   std::cout << std::endl << std::endl;
   std::cout << "CALLBACK: "
               << "setFirewall Response"
               << (error == telux::common::ErrorCode::SUCCESS ? " is successful" : " failed");
};

5. set firewall mode based on profileId, enable/disable and allow/drop packets

dataFwMgr->setFirewall(profileId,fwEnable, allowPackets, respCb);

6. Response callback will be called for the setFirewall response
