I connected a machine to a gigabit switch. It can ping the router (which is connected to the switch but it cannot ping any other machine on the subnet. It does, however, respond to ping.
What could cause this?
i've tried resetting the tcp stack.
Windows 7 x64
Broadcom Netlink onboard NIC
Watchguard 25-W router
Looks like this:
Watchguard Port 0 -> Tompson DSL Modem
Watchguard Port 1 -> DLink DGS-108
Computers and printer connect to DGS-108
192.168.2.18 (computer 1)
192.168.2.19 (computer 2)
.18 can ping .19 and everything else and route to the internet
.19 can ping .1 but nothing else, no internet..
