MultiWAN Routing

While somewhat similar to the Routing menu, the MultiWAN Routing menu allows you to direct outbound traffic in multiwan scenarios.

Here, you can define advanced parameters to make a connection bind to a specific WAN interface. Where outbound traffic is directed will implicitly affect the corresponding (inbound) return traffic. A packet going to WAN0 should return only via the same interface.

On: when checked, this enables the routing rule on that line of the table.

Protocol: lets you choose the transport protocols to be matched by the rule.

Hundreds of L4 protocols exist. This setting refers to the most common ones.

• All Protocols * (Default).
• TCP + UDP
• TCP
• UDP
• ICMP

Source Address: filters in the defined source of traffic.

• All - filters in all LAN devices.
• IP - lets you define a specific IP address or set of addresses.
  using a netmask syntax (e.g. 192.168.1.0/24).
• MAC - binds the rule to a defined MAC Address only.

Destination Address: Similar to source address, but makes a more restrictive rule, based on destination address.

• All - all IP Addresses on the Internet.
• IP - one ore more IP Addresses (in netmask format).
• Domain - a destination domain.

Select WAN: (WANx) - here, choose the logical interface where defined outbound traffic will be directed.

Description: in this field, enter any notes to help you make management easier.

Note that Rules defined will take precedence over any WAN's weight-related setting.
