Hello,
My ISP has asigned me 5 public ip adresses.
I assigned first one to my Eth1 gateway.
Eth2 is for LAN. Ports Eth3, Eth4 are slaves to Eth2.
Lan users have Internet access. All works great until here 
Next, I want to assign second public address to Web server.
The goal is to put real public IP adress on web server ethernet card.
All traffic should go through mikrotik firewall to prevent DDOS, traffic control, etc..
Plugged my Web server into Eth5 port, and ??? what’s next? Should I bridge Eth1 and Eth5?
Please help me!
