I've been trying out DUAL WAN Load balance, it seems the cable modem is picky, I got it working by using the mac clone feature.
when my cable modem was provisioned they used the cable modem mac address, and at the time it was connected
to the ASUS router WAN port. I used that WAN port (eth0) mac address in the WAN Type Ethernet LAN mac Address (LAN port 4).
At the command line ifconfig shows WAN eth0, has the exact same address as LAN port 4 eth1.
Either the command line is not showing true mac address for eth1, or something else is going on with DHCP
when cable modem is connected to that port specifically.
the ATT modem also behaved strangely when it was connected to LAN port 4, the DMZ setting on the ATT modem didn't work
eth1 was assigned a private address not a public IP. But at least ATT modem worked on LAN port 4.
ATT DMZ setting you assign which mac address gets the public ip address, so it must have seen another mac address from LAN port 4.
a few times I rebooted the RT-AX88u router then I ssh into the router, I could ping an internet site by hostname inside the router, yet no LAN device in my home had internet access.
both eth0 (WAN) and eth1 (LAN) had ip address from their respective services,
the routes looked normal (route -n).
a quick fix was to kill the udhcpc process with the interface eth1 (LAN port 4)
and relaunch from command line with the same switches i've seen other times.
I did take a snapshot of nvram before and after I got the internet working.
when internet was down the following nvram settings stuck out
aae_sip_connected=0
nat_state=1
after internet worked normally
aae_sip_connected=1
nat_state=2
does someone know what those nvram settings mean?
also question on how can the ASUS router have internet access, yet no devices in my home network
had internet access but they could connect to the ASUS router like my notebook?
worst case I can write a script run from cron, that can check nat_state, if its not 2, to kill the udhcpc process for the eth1 interface
then I don't have to baby sit load balance.
