Hello,
I am new to this chapter and I would need your help.
I have a clear os that is a gw server and a dhcp server.
Has two network boards, one to which the IP class 10.10.x.x is assigned and one to which a routable IP is assigned for the entire network.
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 64:70:02:04:34:e6 brd ff:ff:ff:ff:ff:ff
inet 10.10.0.254/16 brd 10.10.255.255 scope global eth0
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 8c:89:a5:ee:9e:c4 brd ff:ff:ff:ff:ff:ff
inet 93.x.x.x/28 brd 93.122.132.143 scope global eth1

Behind the network I have a lot of cameras that have IPs in the 10.x class and that must be seen from outside the network.
How can I do port forwarding for these cameras and if I have to add those ports to the firewall as well?

please help me
