Bond All Interfaces Setup Guide
As of firmware version 8.5.04, when you specify a non-zero VLAN ID in NAT Mode or
Transparent Mode, you will be given an additional option to “Bond rtr/svr NI”. This feature
allows you to use the “Internet” and “Server” ports as a “single” bonded interface (also
known as Port Channel or Link Aggregation Group). When this option is enabled, the
traditional “front” and “back” LAN of the WebMux is no longer partitioned on the WebMux
itself, rather, on the network SWITCH using tagged and untagged VLAN ID settings.
Specific concepts need to be followed when setting up the WebMux with VLAN IDs. One is
that the ports on the switch connected to the WebMux MUST be configured to be using
“tagged” VLAN (802.1q). VLAN IDs configured on the WebMux for any mode (NAT,
Transparent, or Out-of-Path) is a “tagged” VLAN (802.1q) specification. For the rest of the
network, there are two ways to configure the switch and devices in order for them to be able
to communicate with each other. One way is to make all the devices in the local network use
802.1q VLAN tagging, since only devices using 802.1q VLAN tagging will be able to
communicate with each other. However, that option depends on the actual network interface
in the device and whether or not it supports 802.1q VLAN tagging. The other option is to
leave the network interface configuration on the other devices alone and configure the switch
to do the VLAN tagging. This will be the option that we will be using in our example. All
manageable switches with VLAN capabilities have these features, but since the switch
configuration commands vary from brand to brand, we will only lay out the main
configuration concepts and leave it up to you to refer to your switch user manual for
specifics.
In the following example, we will be configuring a WebMux in NAT Mode using the “Bond
rtr/svr NI” option enabled:
RTR LAN IP: 192.168.12.21
RTR LAN mask: 255.255.255.0
SVR LAN IP: 192.168.11.21
SVR LAN mask: 255.255.255.0
RTR LAN vlan id: 100
SVR LAN vlan id: 200
Bond svr/rtr NI? YES
SVR LAN gateway IP: 192.168.11.1
External Gateway IP: 192.168.12.1
On the switch, we will be connecting ports 1 and 2 to the “Internet/rtr” port and “Server/svr”
ports of the WebMux. We will designate ports 3, 4, 5, and 6 for the “Front/Internet” LAN
and ports 7, 8, 9, and 10 for the “Back/Server” LAN.
First you will need to create a “port channel” or “link aggregation group” that includes
physical ports 1 and 2. In most switches your real ports are designated by 0/1, 0/2, and so on.
