PCC method and connection state clarification.

RouterOS General
1

Hi,
Recently I implemented a PCC method for 2 ADSL lines and load balancing (In Route , distance each 1 and 1 and 2 for load balancing).
About PCC and connection state, I have some questions and some confusions too.

I want to achieve optimal solution. Which option is best that gives best quality and internet speed to be utilized better using PCC.

Below are my questions.

  1. In Mangle Rule is it good to set connection sate to new (there are 3 prerouting rules but state is used 2 times)
    Chain: Prerouting
    Connection State: New

  2. Also in Mangle Rule PCC
    Chain: Prerouting
    In Interface: LAN
    Connection State: New
    Dst Address Type: ! local
    PCC: both addresses OR both addresses and ports OR src address and port (which one is the best)

  3. In mangle rule all passthrough box is checked (except accept rule)

PCC video “https://youtu.be/nlb7XAv57tw?t=431” which starts directly from firewall

Last question. Which method can be used in addition to above to handle single connection. Is it policy routing? Please mention any example.

Thank you
