With the uplink balancing function, you can combine more than one Internet uplink, either to have backup uplinks available or for using load balancing among multiple uplinks. Combining up to eight different uplinks is supported.
Note: The UTM can only route traffic to one interface or another based on rules, or automatically balance the traffic between interfaces based on weight. There is no way to combine speeds of two interfaces into one, virtual or real. You cannot take two 10 Gbps Wan interfaces and create a single 20 Gbps interface. In systems with two 10 Gbps interfaces that are evenly balanced, a single connection may use up to 10 Gbps and a second connection routed out the other uplink can take the other 10 Gbps.
A new virtual network interface named Uplink Interfaces is automatically created and becomes available for use by other functions of the Astaro Security Gateway, e.g. IPSec rules. The virtual network interface Uplink Interfaces comprises all uplink interfaces added to the interface list.
Additionally, a new network group named Uplink Primary Addresses is automatically created and becomes available for use by other functions of the Astaro Security Gateway, e.g. packet filter rules. It refers to the primary addresses of all Uplink Interfaces. If there is an interface failure, open VPN tunnels can be automatically re-established over the next available interface provided DynDNS is used, or the remote server accepts the IP addresses of all uplink interfaces. As a prerequisite, the IPSec rule must use the Uplink Interfaces as Local Interface.
On the Network | Interfaces | Multipath Rules tab, you can set multipath rules if you use the multipath mode for uplink balancing.
To create a multipath rule, proceed as follows:
