I am using CheckPoint Firewall+Smart devices with R80.10. Eth0 connected to LAN with IP 126.96.36.199 and Eth1 connected to WAN with IP 188.8.131.52. I am hosting an FTP server (184.108.40.206) and CCTV DVR (220.127.116.11). I have another WAN IP 18.104.22.168 free which I want to spare for above FTP and DVR servers using any means. The Firewall's Eth0 is the gateway for my entire network.
Should I use NAT, Port Forwarding or any means so that people in Internet can able to access these servers on the said IP? Any suggestions are appreciable, please.
