1 00:00:01,000 --> 00:00:07,330 Hello and welcome to this lecture in this lecture we talk about the course lapped apology and goals. 2 00:00:07,540 --> 00:00:14,470 So I have prepared this apology with three locations the headquarters and two branches and in the first 3 00:00:14,470 --> 00:00:15,850 place we will be going. 4 00:00:15,970 --> 00:00:19,090 And let me just grab a pen. 5 00:00:19,120 --> 00:00:21,550 We will be configuring the HQ for the gate. 6 00:00:21,550 --> 00:00:24,160 We will start with basic setup initialization. 7 00:00:24,190 --> 00:00:30,210 So we will configure IP addressing both on the web interface and on the land interface. 8 00:00:30,220 --> 00:00:32,740 We will also have a management interface here. 9 00:00:32,740 --> 00:00:41,100 So we'll have a P.C. and we will be configuring basically the HQ for the gate through the web. 10 00:00:41,230 --> 00:00:47,700 So the web user interface next will move to the branch for the gate and we will do the same. 11 00:00:47,700 --> 00:00:54,890 We will configure IP addressing and also provide management access through the management port. 12 00:00:55,060 --> 00:00:58,540 And again we will have a management station here. 13 00:00:58,540 --> 00:01:05,500 Now after configuring this two and also configuring connectivity so IP connectivity between the two 14 00:01:05,500 --> 00:01:05,880 sides. 15 00:01:06,400 --> 00:01:09,610 And we will test these through and ICMP session. 16 00:01:09,640 --> 00:01:14,750 So we will ping from branch 48 to H2 48 or the other way around. 17 00:01:14,750 --> 00:01:16,090 It doesn't matter. 18 00:01:16,090 --> 00:01:22,600 We will be configuring the IP VPN setup between the two sites and we will run. 19 00:01:22,600 --> 00:01:25,290 In this case the IP saying VPN wizard. 20 00:01:25,540 --> 00:01:28,780 But anyway you will see that in the upcoming lectures. 21 00:01:28,780 --> 00:01:37,900 Now the end goal if the IP VPN will be successful is that we will have a VPN tunnel built between the 22 00:01:37,900 --> 00:01:38,780 two sides. 23 00:01:38,950 --> 00:01:48,760 And in the end the goal for any site to site VPN is that we can ping between the two pieces so that 24 00:01:48,760 --> 00:01:52,540 they look just as if they were in the same. 25 00:01:53,050 --> 00:02:01,360 So ICMP connectivity between the branch land P.C. and HQ land P.C. should be obtained but at the end 26 00:02:01,360 --> 00:02:03,460 of this configuration. 27 00:02:03,790 --> 00:02:13,600 Now next we will move to the branch where we no longer have a 48 firewall but we have a Cisco say. 28 00:02:13,880 --> 00:02:21,890 So we will configure again here IP connectivity and IP addressing on on the interfaces as any firewall. 29 00:02:21,890 --> 00:02:28,670 This Cisco I say also has a management interface and it's zero by zero but any way we will configure 30 00:02:28,670 --> 00:02:34,610 access so that we are able to talk says the firewall through as the m.. 31 00:02:34,640 --> 00:02:37,670 So the graphical user interface of the Cisco NSA. 32 00:02:38,270 --> 00:02:46,790 And when this is done we will then configure the tunnels the IP SEC tunnel between again the HQ 48 and 33 00:02:46,790 --> 00:02:57,780 the Cisco RSA and again we will have to have ICMP connectivity between the land P.C. of the HQ and the 34 00:02:57,840 --> 00:03:01,050 branch with Cisco as a firewall. 35 00:03:01,050 --> 00:03:08,040 Now as network engineers we do know that sometimes things break or at least they don't work in the first 36 00:03:08,040 --> 00:03:08,910 place. 37 00:03:08,940 --> 00:03:11,610 So we have to be ready in order to troubleshoot. 38 00:03:12,300 --> 00:03:18,890 So what to do in order to troubleshoot IP SEC VPN. 39 00:03:19,530 --> 00:03:25,050 And for this reason I have prepared in the last section of this course a couple of troubleshooting scenarios 40 00:03:25,410 --> 00:03:29,890 so that we are able to overcome these kind of situations. 41 00:03:29,940 --> 00:03:34,530 So troubleshooting scenarios on the 48 firewalls are also included. 42 00:03:35,040 --> 00:03:35,810 So thanks a lot. 43 00:03:35,820 --> 00:03:37,710 And join me in the next lecture.
