I am using CheckPoint Firewall+Smart devices with R80.10. Eth0 connected to LAN with IP 220.127.116.11 and Eth1 connected to WAN with IP 18.104.22.168. I am hosting an FTP server (22.214.171.124) and CCTV DVR (126.96.36.199). I have another WAN IP 188.8.131.52 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.
