    Hello,

    I try to ping a host on LAN side from an other on WAN side but I can't reach it. I saw other messages about this problem but unfortunalty with no answer.

    My configuration is the following :

    - France Telecom Livebox : It is an ADSL modem and router from Inventel.

    Livebox is at address 192.168.1.1 and it is used as a Wifi access point for few hosts. DHCP server is enabled and provides adresses in the range 192.168.1.*

    Livebox is also connected by an Ethernet cable to the WAN port of the WRT54GS.

    - WRT54GS v1.1 with firmware 4.71.1 from Linksys

    WRT54GS is at address 192.168.1.254 for WAN side and 192.168.0.254 for LAN side. It is configured as gateway and DHCP server is enabled and provides adresses in the range 192.168.0.*

    In this configuration I have not problem to access internet :

    - Hosts connected to the Livebox Wifi can access internet and I can use ping with no problem between these hosts

    - Hosts connected to the WRT54GS Wifi or Ethernet ports can access internet and I can use ping between these hosts. From this hosts I can also ping with no problem any hosts connected to the Livebox Wifi

    - From the WRT54GS itself I have no problem to ping any hosts on both sides with the diagnostic ping utility.

    - The problem is from hosts connected to the Livebox Wifi i am unable to ping any hosts connected to the WRT54GS.

    Any help will be appreciated.

    I did a test changing WRT54GS operating mode fron "gateway" to "router" et adding the correct route on host on network 192.168.1.0
    In this configuration ping and HTTP access from host on network 192.168.1.0 (Livebox LAN) to host on network 192.169.0.0 (WRT54GS LAN) work fine.

    The only problem in this configuration is hosts on 192.168.0.0 (WRT54GS LAN) can ping any other hosts on both network except they can not ping the Livebox modem router at 192.168.1.1 and access to internet.

    It is as if Livebox modem router does not accept connection from a router.

    Any help ?
