Doubts about internal ip = external ip



  • 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.



  • Hello, I do NAT but after some time has m external ports that I created stop working. What can be the problem? Do you have any examples?
