Hi ,

I have two LAN IP (LAN and WIFI Traffic) from cisco ASA firewall and it is routed to cisco router ,cisco router is redirect back to Web proxy and web proxy routed back to router as single IP for both LAN and WIFI.

Here i want to do load balance the LAN and wifi traffic in router but due to proxy inbetween all LAN and WIFI traffic combined in single IP.Can you suggest us to do load balance LAN and WIFI traffic in this setup.

Herewith i attached topology diagram
