    ping doesn't return


    I am one step above the newbie level on Linux. I connected SuSE server and one workstation running the same:

    ISP - modem - router - server - switch - workstation

    1. when I PING from the server all pings are properly returned. I can connect to the Internet and workstation without any problem

    2. When I PING from a workstation then it is different
    a. pings return until I reach an outside oddress of the server. I can connect to the server and its files, no problem whatsoever.
    b. when I PING an address of a router or any valid address outside of the server I do not get ANY response. Just like the ping dropped into a black hole. The address is resoved (either IP or "www.xxxx.com"). However, when I ping an unused address I receive a message that the host is unreachable.

    It looks to me like the server does not transmit back any information. Does anyone know how to fix it ??? I appreciate any advise!!
    Thanks guys in advance

    a suggestion, nothing more.

    Have you any kind of firewall on the server (iptables etc.) that has been told not to allow pings or UDP?

    Like I say, just a suggestion.

    Use Suse 10.1 and occasionally play with Kubuntu
    Also have Windows 98SE and BeOS
