NethServer 6

I would like to have more flexibility in MultiWAN configuration, if I have more than 2 providers I would like to be able to:

• set a number of providers always active (as actually in balance configuration)
• set other providers as backup, so they become active only if a specific one of the main providers go out

ex:
provider 1,2,3 always active
providers 4 and 5 as backup

provider 4 become active if prov.1 fall down
provider 5 become active if prov.2 fall down

The idea is to not have a general behavior switch (backup/balance) , but a specific behavior switch for every provider.
