Connecting Cisco Catalyst 3560 to ADSL modem

Dears,

I'm setting up a lab switch, 3560 to a DSL router/modem and i cannot seem to get the routing from VLAN100 to the DSL router/ modem to work.

  • int g0/1 is connected to the DSL router/ modem
  • int g0/10 is connect to the client (10.10.100.10)

 

From the 3560, I can ping the DSL router (192.168.1.1), the client (10.10.100.10) and I can ping the internet.

From the client connected to to the 3560, I can ping the g0/1 interface IP address (192.168.1.201), but not the DSL router (192.168.1.1).

From the DSL router, I can ping the internet and the 3560 g0/1 ip address (192.168.1.201) but cannot ping the client (10.10.100.10)

 

Client Configuration :

IP Address: 10.10.100.10

Subnet Mask: 255.255.255.0

Default Gateway: 10.100.100.1

DNS : 8.8.8.8

Add one static route entry on router/modem like the below:

ip route 10.10.100.0 255.255.255.0 <g*/*> 192.168.1.201
