I have a Cisco 857w router, this is currently connected to the internet and working fine. If I plug a client direct into the inbuilt switch any client can access the internet.
In my office I have several clients connected to a unmanaged 3com switch which itsself is connected to the Cisco router via Cat5e.
The problem I have is that no client connected to the 3com switch can access the internet, however.
All clients can ping the router/gateway.
All clients can ping each other by name and ip address when connected via the switch only.
All clients can ping each other if one is connected direct to the router and the other to the switch.
All cliensts access the internet is connected directly to the router.
No physical cabling has change, the only change that has been made anywhere is on the Cisco router, which was cleared and re configured for a new ISP.
Does anyone have any ideas his is driving me mad now!
