Incoming traffic thru WAN and outgoing thru 4G USB

[Jartsa]

Hi,

Is that possible to do using AC68U router? I have wired ADSL on WAN port and would like to have outgoing traffic going thru 4G because it has better bandwidth than ADSL.

You can but its a bit funny using 2 connections that way. Assuming you use DSL for downloads and 4G for uploads you first need to use RMerlin firmware with iptables.
You set your 4G as your primary connection.
In your router create a rule in forwarding/output from src-nat. What NAT does is replace the LAN address with a WAN address. What you want to do instead is replace the WAN address with the WAN adddress of your DSL interface so it'd look like it is going out of your DSL connection when it is being forwarded to your 4G ISP.

Hmm... Better would be that ADSL line is dedicated to PS4 / IpTV and the 4G would be great for other devices. Could that be done easily? PS4 and TV are wired to router other devices use WLAN. Thanks for the reply.

If iptables can have multiple different NAT rules.
