1 00:00:06,180 --> 00:00:08,250 Hello and welcome to this lecture. 2 00:00:08,280 --> 00:00:15,180 It is now time to verify our configuration both from the test P.C. or user bases or land user up to 3 00:00:15,180 --> 00:00:16,330 the free firewall. 4 00:00:16,470 --> 00:00:21,870 And again going upstream from the free a firewall to the Internet. 5 00:00:21,870 --> 00:00:24,720 So let's start now with the firewall. 6 00:00:25,110 --> 00:00:27,400 So it's 48 1. 7 00:00:27,460 --> 00:00:28,760 We'll have to log in. 8 00:00:28,950 --> 00:00:31,290 So admin no password by default. 9 00:00:31,290 --> 00:00:36,880 Just click enter and let's see if it has connectivity to the Internet. 10 00:00:36,930 --> 00:00:41,330 Again we will do a verification of our routing. 11 00:00:41,640 --> 00:00:43,770 So interfaces first show system 12 00:00:46,290 --> 00:00:51,200 interface tab to autocomplete question mark. 13 00:00:51,780 --> 00:00:57,880 And we see that we have this IP address on port one which is facing upstream to the Internet. 14 00:00:58,110 --> 00:01:03,930 If we want to execute a ping we will not do just pink like in other vendors. 15 00:01:03,930 --> 00:01:12,870 We'll have to say execute Bing and we will bring the Google DNS and connection is successful. 16 00:01:12,870 --> 00:01:14,670 So at this point we know that. 17 00:01:16,320 --> 00:01:22,850 So at this point we know that from the forget firewall we do have connectivity up to the Internet. 18 00:01:22,950 --> 00:01:29,610 It is time also to verify connecting from the land P.C. going to the 48 firewall. 19 00:01:29,610 --> 00:01:32,310 So I will minimize this window. 20 00:01:32,580 --> 00:01:39,650 And again if I try to ping I will see that firewall is not responding. 21 00:01:39,840 --> 00:01:46,980 Well let me let me just say that a firewall is totally different from a router and what I mean by this 22 00:01:46,980 --> 00:01:54,070 is that when you first power up a router it will be completely open. 23 00:01:54,090 --> 00:01:56,100 So nothing block by default. 24 00:01:56,400 --> 00:01:59,760 But on the firewall side it's again different. 25 00:01:59,760 --> 00:02:08,010 And it's because it's totally blocked and you will need to open any IP connectivity any ports any applications 26 00:02:08,010 --> 00:02:09,900 to pass through the firewall. 27 00:02:10,500 --> 00:02:19,470 So at this point I will just show you that indeed communication is working but ICMP hasn't been enabled 28 00:02:19,530 --> 00:02:23,090 yet so hasn't been enabled on the firewall. 29 00:02:23,100 --> 00:02:33,180 If I do a show system interface and port to and click enter it will now show me the configuration of 30 00:02:33,180 --> 00:02:33,880 port too. 31 00:02:34,740 --> 00:02:40,890 So I have the IP and I have some other some other configuration applied. 32 00:02:41,210 --> 00:02:45,930 I will need basically just to allow ICMP connectivity to work on this port. 33 00:02:45,930 --> 00:02:47,110 So let's do that. 34 00:02:47,110 --> 00:02:51,270 So config sys interface enter. 35 00:02:51,330 --> 00:02:58,040 Now you say edit port 2 and we'll say set. 36 00:02:58,560 --> 00:02:59,910 Allow access. 37 00:03:00,070 --> 00:03:04,220 And if you do a question mark now it will provide you the available options. 38 00:03:04,260 --> 00:03:06,090 The first one it's ping. 39 00:03:06,090 --> 00:03:07,010 So let's do it. 40 00:03:07,210 --> 00:03:07,470 Set. 41 00:03:07,500 --> 00:03:09,760 Allow access ping enter. 42 00:03:09,890 --> 00:03:17,110 And again for exiting this configuration menu and applying the configuration you say and and enter. 43 00:03:17,340 --> 00:03:18,750 Let's verify our work. 44 00:03:18,750 --> 00:03:24,860 So show system interface and again port two. 45 00:03:25,260 --> 00:03:27,760 Now it says set allow access ping. 46 00:03:28,200 --> 00:03:29,100 Let's do that again. 47 00:03:29,910 --> 00:03:38,460 So ping now the ping is successful and the basically if we go back to the diagram at this point we have 48 00:03:38,460 --> 00:03:45,090 verified that connectivity is successful between the land B.C. going up to the firewall and at the same 49 00:03:45,090 --> 00:03:49,830 time from the firewall going up to Internet gateway. 50 00:03:50,040 --> 00:03:53,950 Do we have connectivity from the windows P.C. to the Internet. 51 00:03:53,970 --> 00:03:57,430 Ping 8 8 8 8 8 8 8 we do not. 52 00:03:57,450 --> 00:04:05,040 And this is happening because no network others translation has been configured yet on the firewall. 53 00:04:05,040 --> 00:04:07,110 So that will be all for this lecture. 54 00:04:07,110 --> 00:04:09,060 Thank you and see you in the next one.
