Can't ping my router from a switch...
...but I can from a hub?
I've a Cisco RV042G with an IP address of .20 on its LAN interfaces.
I've two desktops running Linux with static IP addresses of .80 and .81
I've a Cisco 300 switch, out-of-the-box flat plug-and-play configuration.
When the two desktops are plugged directly into the router LAN ports they can ping the router and each other.
When the two desktops are connected into a hub which then has one connection to a router LAN port they can still ping each other and the router.
The odd thing is, when the hub is replaced by the switch the desktops can ping each other but not the router. Hub works, switch doesn't. With the hub I get ongoing routing to the WAN and therefore internet, with the switch I don't.
Can anyone shed any light on what might be the configuration problem please?
