OVH's OverTheBox is a multi-WAN service that aggregates traffic from up to four internet connections on a single IPv4 address, ensuring load balancing and active fail-over to maintain connectivity. The system utilizes advanced technologies like MPTCP for TCP session management and is designed to work with various internet providers. Users can easily connect and configure the OverTheBox service through a web interface for enhanced internet performance and redundancy.

4. AGGREGATION
The traffic is split among 2, 3 or 4 internet connections. Our Service aggregates
them on one IPv4 hosted by OVH.

5. LOAD BALANCING
OverTheBox can load balance users or traffic.

6. ACTIVE FAIL-­OVER
OverTheBox can keep you online in the event that one connection should fail while keeping
all active tcp connections.
OverTheBox (OTB) service maintains traffic on the OVH IP hosted.

Aggregation MPTCP
Developed by the university Catholique de
Louvain, MPTCP (http://multipath-­tcp.org/ ) allows
to establish a TCP session on several internet

IP packet transport
We use Shadowsocks for the TCP
trafic and Glorytun to encapsulate
the others traffic, ex:UDP, ICMP

Infrastructure Cloud
On our infrastructure we aggregate the
traffic on a single IPv4.
You get access to peer wirh OVH – No port
restriction
Up to 4 Internet connections
OverTheBox is compatible with all
operators.
The differentboxes are recognized by their
DHCP. After the discovery, OverTheBox is
announced as the Internet Gateway for the
LAN.

21. QUICK START

22. BEFORE STARTING
§ Active DHCP on your modems
§ The subnets have to be different
Modem 1 : 192.168.1.1
Modem 2 : 192.168.2.254
Modem n : 192.168.n.1
§ Start with the first modem
22

23. SUBSCRIPTION TO THE SERVICE & FIRST WAN
§ Connect the OverTheBox like a computer
§ Go to the manager
§ Subscribe to the service
§ Validate the association on http://overthebox.ovh
§ Configure your first WAN
