    Default Can't Ping from Router to Host & vice versa in GNS3

    I am having a very strange problem. I am unable to ping host from router & vice versa.

    I am configuring host with VPCS & setting ip address alongwith gateway. I also saved the config. Yet ping & traceroute gives no result.

    Even I cant ping back from router to host? Is this normal. I tried re-installing GNS3 again, nothing changed.

    Is anybody else having the same issue

    Where are your config and your show commands? What version of GNS3 are you using?

    What is your IP, subnet mask, and default GW of both the router and host? In addition, is there any device in between the router and host i.e. switch or another router?

    I have an ethernet switch between Router & PC. The default GW config is correct for both router & host. Host IP is 192.168.1.2/30.

    GNS3 is on version 1.5.4. Can you do a "show IP interface brief". Maybe in the wrong port.

    Can I suggest you connect the Router directly to the PC with a Crossover Cable and then try the Ping command. That way you'll eliminate the Switch as a possible cause of the problem.
