Simple Routing Problem!?

Simon DM
Level 1
Level 1

Hi,

I have setup a SG300 (in L3 mode) as below but can't solve what I thought should be a simple problem, but cannot for the life of me figure it out.

PC1 and PC2 can ping each other and 192.168.1.100 (port GE1). So I'm happy that VLAN setup and DHCP seems fine. But neither PC1 or PC2 can ping 192.168.1.1, and therefore cannot access the internet.

My routing table looks like this:

S   0.0.0.0/0 [1/1] via 192.168.1.1, 01:25:11, vlan 1
C   192.168.1.0/24 is directly connected, vlan 1
C   192.168.3.0/24 is directly connected, vlan 3
C   192.168.4.0/24 is directly connected, vlan 4

The Switch can ping 192.168.1.1 from the web ui if I select the Auto or 192.168.1.100 interface. But not from the VLAN interfaces. I have not added routes back on the router to the switch - but this shouldn't matter, I had a similar setup on my old switch and no problems. Trace routes from either PC show nothing but timeouts. 

Network layout below.

Can anyone see why I cannot access the router from the VLANs? There are no ACL's in place.

Thanks

Simon

I am guessing your router does not have routes to 192.168.3.0 and 192.168.4.0  

so add static routes to it, point to 192.168.1.100 (SG300)

cheers
