libp2p-upnp crate provides zero configuration options, so this has to be fixed in upstream crate. Will create an issue in rust-libp2p.

[hanabi1224]

I looked into the source code of go-libp2p and rust-libp2p and had below findings: (will make a feature request to rust-libp2p soon)

• go-libp2p-upnp makes 3 attempts discoverUPNP_IG1 (), discoverUPNP_IG2 () and discoverUPNP_GenIGDev while what rust-libp2p-upnp does is equivilent to discoverUPNP_IG1.
• go-libp2p-upnp tries to map an internal port to a random external port with reties, while rust-libp2p-upnp tries to map an internal port to the same external port.

func discoverUPNP_IG1(ctx context.Context) ([]NAT, []error) {
	return discoverSearchTarget(ctx, internetgateway1.URN_WANConnectionDevice_1)
}

func discoverUPNP_IG2(ctx context.Context) ([]NAT, []error) {
	return discoverSearchTarget(ctx, internetgateway2.URN_WANConnectionDevice_2)
}

// discoverUPNP_GenIGDev is a fallback for routers that fail to respond to our
// targetted SSDP queries. It will query all devices and try to find any
// InternetGatewayDevice.
func discoverUPNP_GenIGDev(ctx context.Context) (nats []NAT, errs []error) {
    ...
}

Closing as the issue has been escalated to the upstream.
