3560G unable to Ping Router or External Network

zbresser

I am setting up my first Cisco Switch, its a 3560G and I'm going to use it to segment my network with Vlans, I have followed this guide.






All I have connected right now is my router (cheap Home router) and I can ping devices on my local network 192.168.1.0/24 except for the router (can ping its interface 192.168.1.200 but not its ip 192.168.1.1) and I am unable to ping externally such as google.com or 8.8.8.8 if I ping google.com I get:

    CORESW01#ping google.com
    Translating "google.com"...domain server (255.255.255.255) [OK]


    Type escape sequence to abort.
    Sending 5, 100-byte ICMP Echos to 172.217.8.206, timeout is 2 seconds:
    .....
    Success rate is 0 percent (0/5)

As you can see it is grabbing a valid IP for the domain google.com but is
for some reason unable to route to it.






I am also able to ping the switch from a client that is not connected to the switch (they both are connected to the router), but from a device connected to the switch I am unable to ping externally as well but can ping other Vlan interfaces such as 10.0.100.1






I have attached a network diagram, the only difference is the interface between the router and the switch is 192.168.1.200 not 192.168.1.2

Here is show ip route

    CORESW01#show ip route
    Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
     D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
     N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

     o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
     + - replicated route, % - next hop override
    
    Gateway of last resort is 192.168.1.1 to network 0.0.0.0
    
    S* 0.0.0.0/0 [1/0] via 192.168.1.1
     * 192.168.1.0/24 is variably subnetted, 2 subnets, 2 masks
    C* 192.168.1.0/24 is directly connected, GigabitEthernet0/24
    L 192.168.1.200/32 is directly connected, GigabitEthernet0/24

I'm sure its something stupid I messed up and any help would be appreciated.
