I am using the RB1100AHx2 - Router with 6.38.3 FW.

I followed the Load balancing wiki from here : https://wiki.mikrotik.com/wiki/Improved ... e_Gateways
However I run into the below issue when i run this command :
add chain=prerouting in-interface=LAN connection-state=new nth=1,1,0 action=mark-connection new-connection-mark=odd passthrough=yes comment="" disabled=no

invalid value 1,0 for packet, an integer required

Give this a try.
