Newbie routing issue on 2610

[zenobepeel]

We our stumbling upon a simple issue:
- Switch has a fixed IP in the default LAN: 192.168.0.88
- we've setup a VLAN in another subnet: 192.168.11.0/24
- a laptop connected to a port in the second VLAN can only ping until the 192.168.0.88 and not beyond
- the default gateway 192.168.0.1 is a commodity router
Is must be something simple we are missing here, please help.

Configuration file

hostname "ProCurve Switch 2610-24" 
ip default-gateway 192.168.0.1 
ip routing 
snmp-server community "public" Unrestricted 
vlan 1 
   name "DEFAULT_VLAN" 
   untagged 13-28 
   ip address 192.168.0.88 255.255.255.0 
   no untagged 1-12 
   exit 
vlan 10 
   name "IPTV" 
   untagged 1-12 
   ip address 192.168.11.1 255.255.255.0 
   exit 
ip route 0.0.0.0 0.0.0.0 192.168.0.1

Hello,

have you set the default gateway for your laptop to 192.168.0.88 or 192.168.11.1?

[zenobepeel]

We tried both configurations:

- laptop in  192.168.11.2 with gateway 192.168.11.1

- laptop in  192.168.11.2 with gateway 192.168.0.88

- laptop in  192.168.11.2 with both ip 's as gateway

Thanks for your reply.

Can you test this:

Vlan1:

Computer with Gateway: 192.168.0.88

Vlan 10:

Laptop with Gateway: 192.168.11.1

Using the 192.168.0.88 gateway I'm able to ping to anywhere.

Using the 192.168.11.1 address: is stops at the switch 192.168.0.88

Tnx

The default gateway for any network is always the router address on that same network.

The address and subnet mask determine what addresses are on that local IP network. The only way a device on that network can to talk to another network is to send the request to the router address on that network (gateway address).

Bob,

Does this mean the only way to solve the puzzle is to add a router to the picture to route traffic from VLAN 2 to the internet ? I was under the impression that there was basic layer 3 functionality available in the 2610 models. It can merely serve as routing between VLAN's, no  way to address this current issue, using the 192.168.11.1 address as gateway?

They way you have the router configured is correct. If you have computer connected to VLAN 10 (ports 1-12), and the IP address is 192.168.11.x (2-254) Mask 255,.255.255.0 GW 192.168.11.1, it should be able to ping the 192.168.0.1.

If the route does not have a route statement telling it where the 192.168.11.0/24 (i.e. ip route 192.168.11.0 mask 25.255.255.0 192.68.0.88) network is, then the return packets never maket it back to the 2610 to get routed back to the client.

Let me correct a typo/incomplete statement from before:

They way you have the router configured is correct. If you have computer connected to VLAN 10 (ports 1-12), and the IP address is 192.168.11.x (2-254) Mask 255,.255.255.0 GW 192.168.11.1, it should be able to ping the 192.168.0.1.

If the upsteam router (192.168.0.1) does not have a route statement telling it where the 192.168.11.0/24 (i.e. ip route 192.168.11.0 mask 255.255.255.0 192.68.0.88) network is, then the return packets never maket it back to the 2610 to get routed back to the client.

Sorry about any confusion.

Thank you BGraham_1 for the reply. I'm most grateful.
