Third WAN

[ligeza]

Is it possible to use LAN2 as third WAN? I know that it isn't possible with GUI but if it could be done with scripts I would like to do it with your little help.

In what way do you intend to use it?

It should be possible using vlans, but I haven't looked into how vlans are used even with just two WANs so I can't give you any more details.

(I've just managed to understand how the vlans are used with one WAN...)

What is the output of robocfg show? This will show what vlans are configured in the switch.

And the output of cat /proc/net/vlan/config will show what vlans are configured in the router kernel.

I have more then two internet connections. In Tomato firmware there is possibility to have up to 4 WANs, but I prefer Merlin.
I could make fourth vlan, but how to connect it with the port on router and made it to discover IP from DHCP.

robocfg vlan 1 ports "3 4 5t"
robocfg vlan 4 ports "2 5t"

And I wonder if the rest of it is doable.

I have more then two internet connections.

But that does not answer the question I asked

Do you want to perform load balancing? Probably won't work very well (since it doesn't work very well with two WANs).

Different routes for different addresses? Sure, no problem.


My intention of asking the questions was to find out how the router normallt does when using LAN1 as an additional WAN port. What you would need to do is just mimic that for yet another LAN port.

Note that setting up vlans in the switch (using robocfg) is just like creating a virtual switch (isolated from the rest of the network). The you need to make virtual network interfaces to connect the router to the vlan.

Does ifconfig show all vlans as interfaces?

I made a simple PHP script to select which internet connection I want to use. So if I see if another person in my home is watching some VOD or the Wan is overloaded, I'm switching to another internet connection. Max I get from each WANs is about 3-5mbit/s. To switch between WANs I use "ip rule".
