My ISP (TIM) assigns the same gateway 192.168.100.1 for every pppoe connection and in default state I have this:
route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default 192.168.100.1 0.0.0.0 UG 0 0 0 pppoe-wan
192.168.1.0 * 255.255.255.0 U 0 0 0 br-lan
192.168.100.1 * 255.255.255.255 UH 0 0 0 pppoe-wan
192.168.168.0 * 255.255.255.128 U 0 0 0 wl0_1
192.168.168.128 * 255.255.255.128 U 0 0 0 wl1_1
I'm trying to have a new vlan (br-lan2) that only uses a new wan2 connection, ppoe-wan2. I set a separate metric for wan and for wan2 and I have this:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default 192.168.100.1 0.0.0.0 UG 10 0 0 pppoe-wan
default 192.168.100.1 0.0.0.0 UG 20 0 0 pppoe-wan2
192.168.0.0 * 255.255.255.0 U 20 0 0 br-lan2
192.168.1.0 * 255.255.255.0 U 0 0 0 br-lan
192.168.100.1 * 255.255.255.255 UH 0 0 0 pppoe-wan
192.168.100.1 * 255.255.255.255 UH 0 0 0 pppoe-wan2
192.168.168.0 * 255.255.255.128 U 0 0 0 wl0_1
192.168.168.128 * 255.255.255.128 U 0 0 0 wl1_1
but I'm able to only use the wan with the lowest metric, I'm not able to use both the wans at the same time.
To use them ad the same time I had to use a new routing table for wan2 and in this case I'm able to test both them:
ping -c 5 -I pppoe-wan 8.8.8.8
ping -c 5 -I pppoe-wan2 8.8.8.8
but I don't think that this is a correct way to proceed.
Could I manage this configuration with mwan3? In the mwan3 wiki seems that it is able to only manage wans with different gateway. Is this correct?
