Rules between two interface port tabs
I am confused about rules orders and roles of floating tab.
Why floating rule tab has specialty?
If I create rule in floating tab, and choose two interface tabs (LAN and SERVERZONE),
Does it means that this rule controls the packets flows between LAN and SERVERZONE?
If I don't create floating rules about two interfaces, server (which is placed after SERVERZONE) can't get packets from outside?
Why can't I just create Allow any to any in LAN and SERVERZONE respectively?
Because currently I have an issue without floating rule, server can't get packets from outside.
Help me please,
