We want to have an office server, we already have static IP. But the thing is that we need to have following structure:
ISP Modem Router Server Wireless router
Also I'v tried another option like:
ISP Modem Server Router Wireless router
But it seems to me, that router conflicts with server, therefore one of them doesn't work.
UPDATE 1
ISP Modem - STATIC IP HERE Server - I NEED THIS TO HAVE STATIC IP, without it i can't install DirectAdmin %) Router - I need to have access to the internet from Modem Wireless router
