Power Connect 6248 Internet Routing

Question

I'm try connect to internet from VLAN 103.

The 6248 port g1 is the direct connection to the router.
It's a Linksys RV042.

My PC is connect to port g2 in VLAN 103.

I can ping PC 6248 192.168.103.200
I can ping Linksys RV042 192.168.10.254
I can not ping ISP or internet ip.

This is PC 6248 Configuration

Perform a trace to a website from your PC. Reply with where it hangs up at. Also, have you verified your router is routing correctly to the isp?

Can you ping 192.168.10.254 from your pc? The reason I ask is because if so it would have been the next hop after 192.168.103.200.

Can you paste the routes that you have entered on your router?

kearme · Answer

#show ip route

S 0.0.0.0/0 [1/0] via 192.168.10.254, vlan 10
C 192.168.10.0/24 [0/0] directly connected, vlan 10
C 192.168.101.0/24 [0/0] directly connected, vlan 101
C 192.168.103.0/24 [0/0] directly connected, vlan 103

What has this ip address 192.168.103.220?

Also, have you entered routes to the different vlans in your router?

Yes, can ping 192.168.10.254, but can't ping ISP Gateway [190.4.9.81]or internet IP.

nlspears · Answer

Perform a trace to 192.168.10.254 from your pc and post it.

Crzywolf · Answer

Ok, are you using the IP addresses of the vlan interfaces as the default-gateways of your PC's?

StarLog · Answer

Kearme,

The config looks good.

Seems your using the following for the ip range of the vlans:
192.168.101.200 vlan101
192.168.102.200 vlan102
192.168.103.200 vlan103

They try to go to the internet thru the route statement of:

ip route 0.0.0.0 0.0.0.0 192.168.10.254 which is connected to the Linksys RV042.
BTW, I have two of those routers, they are sweet.

You will need to set a route in the RV042 to find the vlan gateways.
Something like this

ip route 192.168.101.200 ip-address-of-the-RV042-internal

If you ping from the PC, and can ping the 6248 gateway for the vlan, it is getting that far.
If you ping the interface for the RV042, and no response, that means the RV042 has no idea how to get back to the vlan 101 or 102 or 103.

Make some routes.

Like crzywolf mentioned, you will need to change the DHCP scopes, so the default gateways for the differrent IP ranges, is set to the vlans gateway address.

So, for scopre 192.168.101.000/24 set the default gateway in the the DHCP server to 192.168.101.200

Crzywolf · Answer

Turn off ip local proxy-arp on vlan 103, quit being a wuss and use the CLI.  For some weird reason, when you use the web gui to create the vlans, it enables it.  Real men use command line.

StarLog · Answer

I second that, and the gui, can mess up other sections.
