I have written a simple [BSD sockets] test program and have undergone repeated testing,
As a result, when I was browsing the web using Safari for a period of time, there was an outbound network outage, but I was able to connect to the computer using vnc。
This means that there is a problem with the outbound network, but the inbound network is normal。
I guess this may be related to my network proxy scheme
This is my transparent proxy setting:
NETransparentProxyNetworkSettings *settings = [[[NETransparentProxyNetworkSettings alloc]initWithTunnelRemoteAddress:@"127.0.0.1"] autorelease];
NSMutableArray *rules = [NSMutableArray array];
NSArray *ports = @[@80,@443];
for(NSNumber *port in ports){
NENetworkRule *rule4 = [[[NENetworkRule alloc]initWithRemoteNetwork:[NWHostEndpoint endpointWithHostname:@"0.0.0.0" port:[port description]]
remotePrefix:0 localNetwork:0 localPrefix:0
protocol:NENetworkRuleProtocolTCP
direction:NETrafficDirectionOutbound] autorelease];
NENetworkRule *rule6 = [[[NENetworkRule alloc]initWithRemoteNetwork:[NWHostEndpoint endpointWithHostname:@"::" port:[port description]]
remotePrefix:0 localNetwork:0 localPrefix:0
protocol:NENetworkRuleProtocolTCP
direction:NETrafficDirectionOutbound] autorelease];
[rules addObject:rule4];
[rules addObject:rule6];
}
settings.includedNetworkRules = rules;
[self setTunnelNetworkSettings:settings completionHandler:^(NSError * _Nullable error) {
//my handle
}];
I debugged the network extension and found that the network extension did not have any state transitions.
but - [NETransparentProxyProvider handleNewFlow: (NEAppProxyFlow *) fw] is not being triggered.
The outgoing BSD socket connection already established at this time
When there is no data exchange, it normally closes and exits.
When I upgraded OS 11.4 M1 to OS 13, the same test program did not reproduce the problem of network outages.
I can provide the information you need as much as possible。
My problem is, even if the way I set up outgoing BSD socket connection is incorrect,
Why is the
[NETransparentProxyProvider handleNewFlow: (NEAppProxyFlow *) fw]
callback not being triggered
