DHCP not Working and "Unable to load page. Check your Network Connection"

Fabian Noack

Hallo, atm i am testing the XG firewall in our company in my VMware Workstation.

My PC has two RJ45 Ports. One is going to our network, the other one i use for the lan of the XG.

My XG has the 172.16.16.254 (Port 1 in XG), the Windows networkadapter is set to 172.16.16.1 (mask: 255.255.255.0). The second adapter is configured through DHCP for 10.1.X.X/16, the Firewall is getting the 10.1.3.177(Port 2 in XG). Both ports are bridget in the VM.

I gave my Surface the 172.16.16.88 and connected it per LAN to the 172.16.16.1 Port and was able to ping and configure the XG with my webbrowser.

Then i wanted to try DHCP, did it like the manual from Sophos said, 172.16.16.50-172.16.16.80 is my range. Than configured my Surface to use DHCP, connected them but i dont get an 172.16.16.X ip. So i tryed another device, same problem. I allready googled, deleted the dhcp configuration in Xg and made a new one. I have no idea why it doesnt work. And Yes, the Xg Service says "running" for DHCP. Also i tried to give a static ip to my surface through the XG, failed too. So what am i doing wrong?

 

My second problem is that i get the errormessage "Unable to load page. Check your Network Connection" since today. After i recognized it today i took a backup from my VM which worked 4 days ago, same problem. Admins looked in our firewall, no rules changed... Our DNS at 10.1.3.98 is reached from my firewall (XG shows a green dot). So i am unable to do updates  and so on. Has anyone an idea?

 

I hope someone can help me, thanks for your time and have a nice Weekend ;)

    I guess there is something wrong with your Vmware config.Maybe you mixed up the interfaces? 

    Check the MAC of the VMware and compare them with both Interfaces on XG. Are they proper configured?

    Untick use interface IP as gateway and manually type in the gateway address. There is a known issue at the moment when that tick box is selected.

    Thanks. I found out that the windows firewall rule for ICMPv4 got deactivated (how ever). After that i used your solution and unticked the box, typed the gateway in myselfe and it worked :)

    The reason for the connection error was my IP, i changed the 172.16.16.254 to 172.16.16.3 and now i am able to access the internet againe. (I dont know whats the proble and i solved it accidentally...)
