Hello all, I have created a lab for testing purpose but I have a problem on routing. Here my config : site 1 & site 2 can ping each other and they can ping the host. but they can't ping the router (192.168.0.254) Does anyone have a clue about why ? If you need more information ask me. Thank you.

The router at 192.168.0.254 needs information about 192.168.1.64/26 and 192.168.1.0/26 in its routing table. Without routing information, that router will not know how to get packets back to the source computers. IF the Freebox has a default route to the internet and no other routing information, any packet it receives that is not on the 192.168.0.0/24 network will be sent on its way to its default gateway.

As Jorge said, the external router at 192.168.0.254 has no information about the 192.168.1.0 subnets. It only knows about 192.168.0.0 (because it has an interface in that network). If it is going to route traffic to 192.168.1.0 addresses it has to know where to send it. The simplest solution is to add a static route to this router (the Freebox) telling it how to reach the 192.168.1.0 subnets. Something like 192.168.1.0 255.255.255.0 192.168.0.5 This should get all 192.168.1.0 traffic to the internal router and this router can then deliver it to the appropriate internal network (because it has an interface in both those networks). This is called a bundled route, because it covers all your internal subnets. Bundled routing is simpler than adding a static route for each individual subnet. You could in fact use 192.168.0.0/16 and it would cover any 192.168 internal subnets you might have. Bill

Thank you for your information, It's not possible to add static route on the freebox (192.168.0.254) so I have remove the router option so it is bridged now & added my own router. it works perfectly now with the good configuration. Thank you guys
