Hello, I have a really simple setup here, a working stack with tree 4300 prosafe M4300-12X12F, M4300-52G and M4300-28G. each one with the last firmware 12.0.7.7 I have two vlan : vlan 30 (192.168.3.0/24) et vlan 40 (192.168.4.0/24). I follow this kb to create them https://kb.netgear.com/30818/How-to-configure-routing-VLANs-on-a-NETGEAR-managed-switch-with-shared-internet-access I activate routing on each vlan #vlan routing 30 and #vlan routing 40 I activate routing for the switch (Config)#ip routing In Learned Routes, i get : Network Address Subnet Mask Protocol Route Type Next Hop Interface Next Hop Address Preference Metric 0.0.0.0 0.0.0.0 Default Static vlan 30 192.168.3.1 1 0 192.168.3.0 255.255.255.0 Local Connected vlan 30 192.168.3.254 0 0 192.168.4.0 255.255.255.0 Local Connected vlan 40 192.168.4.254 0 0 I use my own dhcp server on each vlan with the right gateway, 192.168.3.254 for 192.168.3.0/24 subnet and 192.168.4.254 for 192.168.4.0/24 subnet. And now, my problem: from 192.168.3.0/24 subnet, I ping the two gateways 192.168.3.254 and 192.168.4.256 I can ping a linux VM 192.168.4.22 but not another one with the same config on 192.168.4.10 from 192.168.4.0/24 subnet, I ping the two gateways 192.168.3.254 and 192.168.4.256 but i can't ping anything else on 192.168.3.0/24, and not my internet gateway 192.168.3.1 I reconfigure 3 times the vlans now with the #clear config command before... I don't find what i doing wrong Thanks for your help.

Hi colinauger Ok, I got your requirement. Currently, you only face one problem: when workstation on Vlan30, only can ping VM1, but cannot ping VM2; but when workstation on Vlan40, both can ping VM1 and VM2, right? Could you please double check as below step: 1. From VM1, check ping 192.168.4.254 and 192.168.3.254; 2. From VM2, check ping 192.168.4.254 and 192.168.3.254;

M4300-52G ProSAFE InterVLAN Routing

Hello,

I have a really simple setup here, a working stack with tree 4300 prosafe M4300-12X12F, M4300-52G and M4300-28G. each one with the last firmware 12.0.7.7

I have two vlan : vlan 30 (192.168.3.0/24) et vlan 40 (192.168.4.0/24). I follow this kb to create them https://kb.netgear.com/30818/How-to-configure-routing-VLANs-on-a-NETGEAR-managed-switch-with-shared-internet-access

I activate routing on each vlan #vlan routing 30 and #vlan routing 40

I activate routing for the switch (Config)#ip routing

In Learned Routes, i get :

Network Address	Subnet Mask	Protocol	Route Type	Next Hop Interface	Next Hop Address	Preference	Metric
0.0.0.0	0.0.0.0	Default	Static	vlan 30	192.168.3.1	1	0
192.168.3.0	255.255.255.0	Local	Connected	vlan 30	192.168.3.254	0	0
192.168.4.0	255.255.255.0	Local	Connected	vlan 40	192.168.4.254	0	0

I use my own dhcp server on each vlan with the right gateway, 192.168.3.254 for 192.168.3.0/24 subnet and 192.168.4.254 for 192.168.4.0/24 subnet.

And now, my problem:

from 192.168.3.0/24 subnet,

I ping the two gateways 192.168.3.254 and 192.168.4.256

I can ping a linux VM 192.168.4.22 but not another one with the same config on 192.168.4.10

from 192.168.4.0/24 subnet,

I ping the two gateways 192.168.3.254 and 192.168.4.256

but i can't ping anything else on 192.168.3.0/24, and not my internet gateway 192.168.3.1

I reconfigure 3 times the vlans now with the #clear config command before... I don't find what i doing wrong

Thanks for your help.

Hi colinauger

Ok, I got your requirement.

Currently, you only face one problem:

when workstation on Vlan30, only can ping VM1, but cannot ping VM2;

but when workstation on Vlan40, both can ping VM1 and VM2, right?

Could you please double check as below step:

1. From VM1, check ping 192.168.4.254 and 192.168.3.254;

2. From VM2, check ping 192.168.4.254 and 192.168.3.254;

Hi colinauger

Welcome to the community!

Could you please share your network topology?

I just want to know:

1. VLAN30 IP address of switch.

2. VLAN40 IP address of switch.

3. As you say, DHCP Server(192.168.3.254 and 192.168.4.254) of VLAN30 and VLAN40 is working as Gateway role, right? If so, there is no necessary to enable routing VLAN on switch, just setup L2 VLAN is enough. As all Layer 3 packet will be forwarded by Gateway(DHCP Server).

Hope it helps!

  Hi EricZ,
  
  Thx for your help! I certainly misanderstand key concept here.
  
  this our network :
  
  1. VLAN30 IP address of switch. = 192.168.3.254
  
  2. VLAN40 IP address of switch. = 192.168.4.254
  
  3. As you say, DHCP Server(192.168.3.254 and 192.168.4.254) of VLAN30 and VLAN40 is working as Gateway role, right? No, (see attached file) I use two dhcp server for each subnet but they are note the gateway of the subnet. I dont want to use them as gateway to avoid traffic bottleneck. On On vlan 30, it is the internet gateway, the switch default route.
  
  from the workstation01, I ping vm1 (192.168.4.22) but not vm2 (192.168.4.21). Vm1 et vm2 are stricly identical. Of course, if i put a workstation on the vlan40, i can ping vm1 and vm2.
