      Hello everyone okay? I'm having a real problem with ips I can not solve in any way, even to work. but for about 2 hours or less hence stops functioning.
      Well ..
      I have a range of 5 ips real and only have two NICs in the PC (firewall).

      How do I distribute these ips to certain machine on the internal network?

      Eg
      The
      Ip: 186.209.77.xx = 192.168.1.105
      Ip: 186.209.77.xx = 192.168.1.106
      Ip: 186.209.77.xx = 192.168.1.107

      If anyone can help I thank you very much …

      hugs

        Depends on what you mean by "How do I distribute these ips to certain machine on the internal network?" Generally you use 1:1 NAT for that.

          I want that to happen in the browser accession following:

          186.209.74.99:8069 = 192.168.1.105:8069
          186.209.74.99:8180 = 192.168.1.120:8180

          Note that the two rules above are using the same external ip, but the internal ip are different

            In that case, use port forwards to do that.
