|Hi, i'll provide some background, and do my best to descripble.|
I have a approx 3 machines that connect to a unmanaged switch, the unmanaged then connects to a modem.router, the modem.router also connects to a wifi.router, some more computers connect to the wifi modem either wireless or wired.
I have two networks 192.168.1/24 and 192.168.2/24 the network is fine from an WAN and LAN perspecitive, all nodes have connectivity both locally and with the internet. I can use rpd and smb to cross both networks.
I've noticed that a single computer on the 192.168.1/24 network cannot be pinged - but I can access the machine with rpd, smb, ftp, from workstations on 192.168.1/24 and 192.168.2/24 networks.
this computer cannot be pinged - but everything works (internet, rpd etc)
I have other machines on that same network which are fine, so far i have tried the following:
set to static ip
set to dhcp ip
set to fixed dhcp
rebooted unmanged switch
the router connected to the 192.168.1/24 network cannot evening ping the machine, but i can see that it's providing internet services..the machine can ping everything else, both no one can ping him...
this is a same fault as the network is operating, but it has my interest...
any networking guys out their?
