the lab is constantly changing and I checked the IP for linux-b one time it was 10.10.10.3 and the next time it was 10.10.10.10
another example is that the linux-b was able to reach 8.8.8.8 but the browser-b could not al though they have the same firewall
I would be very happy if you could do a reset for this lab or rewrite it because it’s imposable to finish the lab
I have tried to pass this lab dozens of time and i could not do it I even used the Network Troubleshooting Basics to try and solve the lab
Here are my tips for this Challenge…
1.) Be sure the firewalls are up… you can open a console and wait for the menu screen.
2.) Linux-A needs to to have it’s IP fixed and it must include DNS configuration. The DNS server IP is 192.168.1.5. 192.168.1.1 is the right gateway. No need to second guess that.
3.) When looking at the configuration page in GNS3 for Linux-A and Linux B, be sure to remove comments ( # ) where needed and ADD comments when needed.
4.) Linux-B is using DHCP. You need to change that AND comment out DHCP. If you leave DHCP configured then the network on Linux-B will not come up. This burned me too.
5.) Linux-B’s IP is not in the DNS server. That is an issue.
6.) The firewall rules and VPN setup are all good. No tricks there. You just need to make sure the VPN tunnel is ESTABLISHED, and if not, well you need to start it.
7.) Fixes are needed on Linux-A, Linux-B, and you need to add a record to the DNS server. The DNS server is GUI driven and pretty easy to figure out.
8.) If you can ping “linux-b” (no quotes) from Linux-A you win. If you have any trouble getting the flag then show me a screen shot of Linux-A pinging “linux-b” by name and I will ensure you get the flag.
