Please, consider these rules :

/ipfirewall mangle
addchain=forward connection-mark=no-mark in-interface=ISP_1action=mark-connection new-connection-mark=WAN1->LANs
addchain=forward connection-mark=no-mark in-interface=ISP_2action=mark-connection new-connection-mark=WAN2->LANs
addchain=prerouting connection-mark=WAN1->LANs src-address-list=LAN action=mark-routing new-routing-mark=ISP1_Route
addchain=prerouting connection-mark=WAN2->LANs src-address-list=LAN action=mark-routing new-routing-mark=ISP2_Route


Once defined Lan ip class = 192.168.1.0/24 , "LAN" src-address-list=192.168.1.0/24 , Lan interface = ether1 , what are the difference in setting the bold section to :

src-address-list=LAN
src-address=192.168.1.0/24
in-interface=Ether1

What is the suggested one ?
Thanks
