cant ping between VLANs on 3750

pgkool001
Level 1
Level 1

Hello all!

I am new to cisco IOS and am trying to setup some basic inter vlan routing. I am unable to ping from one vlan to the other. I just recently purchased a 3750 switch and think i'v got it all setup right. Can someone help?

I have the default vlan 1 setup as ip 192.168.1.0/24 and vlan 3 setup as ip 192.168.3.0/24. The two can not ping each other.

vlan 1 is connected to a consumer router (netgear) which is connected to the internet, and I want vlan 3 to be able to access the internet.

3750switch#show ip route
Codes: 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
       E1 - OSPF external type 1, E2 - OSPF external type 2
       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
       ia - IS-IS inter area, * - candidate default, U - per-user static route
       o - ODR, P - periodic downloaded static route

Gateway of last resort is 192.168.1.1 to network 0.0.0.0

C    192.168.1.0/24 is directly connected, Vlan1
C    192.168.3.0/24 is directly connected, Vlan3
S*   0.0.0.0/0 [1/0] via 192.168.1.1
