Bind:
Interface binding ensures that connections on a given port are sent over a specific WAN connection using the named protocol.

Allowed child options:

ProtocolBindingRule:
Interface binding ensures that connections on a given port are sent over a specific WAN connection using the named protocol. Ranges of ports may also be entered. Leaving the start and end port numbers blank means a port range of 1-65535. Leaving the end port blank means to only use the port given by the start port. Note that not all protocols support ports and such protocols should not specify a port range. The destination and source IP can optionally be given to more specifically match traffic. The optional type of service field assigns the value to the IP type of service parameter to packets matching this rule.

Device Type bindingDeviceType:
Device type of the interface
Device Index string:
Device index as seen in the device list of that type. For WAN 1, you would enter '1' here.
Type of Service tos:
Type of Service parameter to mark matching packets with
Source or Destination IP/Subnet ipnetmask:
Source or destination IP and netmask to match packets against
Notes string:
User-specific notes to help remember the intended purpose of this rule
Start Port port:
Start of the port range to match
End Port port:
End of the port range to match
Protocol protocol:
Internet protocol to bind to this interface

IpsecBindingRule:
Interface binding ensures that connections on a given port are sent over a specific WAN connection using the named protocol. This specialized rule handles binding all transports and ports used by IPsec. The destination and source IP can optionally be given to more specifically match traffic. The optional type of service field assigns the value to the IP type of service parameter to packets matching this rule.

PptpBindingRule:
Interface binding ensures that connections on a given port are sent over a specific WAN connection using the named protocol. This specialized rule handles binding all transports and ports used by PPTP. The destination and source IP can optionally be given to more specifically match traffic. The optional type of service field assigns the value to the IP type of service parameter to packets matching this rule.
