@@ -32,6 +32,12 @@ The key features of Glorytun come directly from mud:
This is the main feature of Glorytun that allows to build an SD-WAN like service.
This allows a TCP connection to explore and exploit multiple links without being disconnected.
* **Traffic shaping**
Shaping is very important in network, it allows to keep a low latency without sacrificing the bandwidth.
It also helps the multipath scheduler to make better decisions.
Currently it must be configured by hand, but soon Glorytun will do it for you.
* **Path MTU discovery without ICMP**
Bad MTU configuration is a very common problem in the world of VPN.

It doesn't rely on ICMP Next-hop MTU to avoid black holes.
In asymmetric situations the minimum MTU is selected.
* **Dynamic and automatic traffic shaping (work in progress)**
Shaping is very important in network, it allows to keep a low latency without sacrificing the bandwidth.
As it is hard to setup, especially in the case of 4G, Glorytun will do it for you.

# glorytun bind 0.0.0.0 to SERVER_IP keyfile my_secret_key &

Here the tricky part... You need to specify your paths or glorytun will not send anything, it's easy:
Now you have to setup your path, let's say you have an ADSL link that can do 1Mbit upload and 20Mbit download then call:
# glorytun path LOCAL_IPADDR up
# glorytun path up LOCAL_IPADDR rate tx 125000 rx 2500000
Again, to check if your path is working, you can watch its status with `glorytun path`.
You should now be able to ping your server with `ping 10.0.1.1`.
