Hi,<\/p>\n

When I have connected my routers defined in GNS3 with a cloud pointing to my network card . HQ was able to access my LAN because it shares the same LAN .But in my Frame-Relay WAN , even if\u00a0 I have all the networks in my routing table , it is impossible for a Branch location to ping something on the real network where you have Windows 7 or Windows Vista machines.<\/p>\n

So after some reseach, I have found this interesting note: http:\/\/www.howtogeek.com\/howto\/windows-vista\/allow-pings-icmp-echo-request-through-your-windows-vista-firewall\/ <\/a><\/p>\n

Even if it is related to Windows Vista and even if you have some warning , it is applying this little patch. When , you apply under the DOS prompt the following command : netsh firewall set icmpsetting 8 enable<\/span><\/em><\/strong> . It will create depending on your topology\u00a0 a new rule inside the Firewall “Networking – Echo Request(ICMPv4)”<\/span><\/strong>. This rule will be enabled.<\/p>\n

In case if you want to revert your manipulation , as the command to revert back present in the previous document is not working , go then top the control center and find the previous created rule or rules and disabled it …<\/p>\n

With this patch , you can enable your Windows 7 to icmp request.<\/p>\n","protected":false},"excerpt":{"rendered":"
