Hello everyone,... I have use openwrt since a few years ago but still noob until now so I want to learn from everyone here
I have a router with 2 wan with pppoe and LTE modem using NCM, also I have VPN tunnel for work to my office. the vpn connect through one of my wan, if pppoe up I prefer that vpn connected to it. then if my pppoe down I have failover my internet and vpn to connect with LTE modem and working well with mwan3.
but after a few time inspecting, my config have lots of problem, when just 1 wan online and lots of traffic my vpn really slow, I assume too much traffic eat my wan bandwidth so if vpn really slow I cannot remote to my office using RDP.
so the first question, is there any solution to split wan to vpn maybe using ratio 40% of total wan connection?
I plan to subscribe 1 pppoe again for vpn, but it will goes same case because I use failover and if one of my wan down the traffic just go through 1 wan.
here the illustration for now
Openwrt router ---- pppoe-wan ---- inet
|
VPN tun
|
---- LTE modem ---- backup
and I plan for future config
Case 2 pppoe online
WAN 0 ---- VPN tunnel only ----->
WAN 1 ------> internet
case if WAN 0 or WAN 1 down
WAN 0/1 --- VPN tunnel (40%) ---->
------> internet (60%)
