WEBVTT 00:07.800 --> 00:15.580 So we have discussed dynamic net and the opposite to the endemic net is static net and static net. 00:15.600 --> 00:23.620 One internal IP address is always mapped to the same public IP address. 00:23.640 --> 00:32.340 A good example is when you have a web server on your private plan and you wish to add any one that connects 00:32.340 --> 00:41.100 to your or when interface to your intimate facing interface will always reach that web server. 00:41.150 --> 00:51.300 Now if you have a pool of IP addresses you can assign one IP address to that web server in 48. 00:51.390 --> 01:02.840 We call it virtual IP addressing or fake let's see how that works let's move over to our network interfaces 01:02.840 --> 01:05.760 and create that virtual IP. 01:05.900 --> 01:15.980 So we have a win and Internet facing court which is at eighty four and a two hundred twenty eight sixty 01:15.980 --> 01:16.440 nine. 01:16.520 --> 01:18.900 Two hundred thirty four. 01:19.160 --> 01:28.860 That's our public IP and we have a local area network at the 10 to 0 3 0 subnet. 01:28.880 --> 01:38.000 Now we have a web server that is located on our local area network and that web server is on the 10 01:38.170 --> 01:42.520 0 the treat of 22 as you can see in our drawing. 01:42.620 --> 01:52.640 We need any host that is entering through our one interface to reach our web server on port 80. 01:52.640 --> 02:05.160 So the next thing to do is to create a firewall address with our Web server address let's name it Web 02:05.160 --> 02:11.760 server 1 let's create the range for that 02:19.360 --> 02:30.410 web server we can use our LAN interface as the interface and that's about it Web server 1 is our address. 02:30.410 --> 02:36.700 Objects that we will use later on on our policy all right. 02:36.750 --> 02:37.670 There we have it. 02:38.180 --> 02:43.860 And now the second thing to do is to create the virtual IP let's create the mapping the mapping itself. 02:43.950 --> 02:55.360 So we'll create a virtual IP let's name it to server 1 interfaces are when interface the external IP 02:55.360 --> 03:07.800 range or IP address is when IP address the mapped the IP address that we will redirect packets is the 03:07.800 --> 03:10.150 tendency or the tree the twenty two. 03:10.420 --> 03:23.140 And we will use ports forwarding to limit our port mapping only to port 80 All right so we have created 03:23.200 --> 03:25.480 the firewall address. 03:25.660 --> 03:28.170 We have created the virtual IP. 03:28.210 --> 03:31.620 The third thing is to create our policy. 03:32.180 --> 03:40.910 Let's lay our policy to circle one of the incoming interfaces when the outgoing is the land. 03:41.110 --> 03:44.300 This source is just about anyone. 03:44.380 --> 03:51.910 Our destination is web server 1 or service is 0. 03:54.640 --> 04:01.690 But don't forget to disable net since we are already mapping it using virtual IP. 04:02.950 --> 04:05.130 And that's about it.
