HP 5412zl IP Routing problem
At first I just wanted to see if I could get the VLANs and routing between them to work and no I couldn't.
The Default VLAN seems to route to the other VLANs with out problem. But the created VLANs can only Ping the Gateway adresses for the VLANs and the Gateway of the Firewall.
IP routing is enabled, VLANs have manually configured IP's, ip route 0.0.0.0/0 x.x.x.x configured to our main firewall. Even tried out Default VLAN as ip route 0.0.0.0/0 x.x.x.x, but no routing between VLANs.
I have updated the firmeware, rebooted and still no routing between VLANs. But when a computer from Default VLAN connect to another PC on another VLAN, then that PC can Ping the PC on the Default VLAN.
What is missing here?

Re: HP 5412zl IP Routing problem
pc default gateway address must be vlan ip address
for example
for vlan 1 pc
ip adress 192.168.249.10
subnet mask 255.255.255.0
default gateway 192.168.249.145
for vlan 240 pc
ip address 192.168.240.10
subnet mask 255.255.255.0
default gateway 192.168.240.50

Re: HP 5412zl IP Routing problem
>>> ip default-gateway 192.168.249.50
>>> ip route 0.0.0.0 0.0.0.0 192.168.249.195
the default gateway is neccessary for routing between the VLAN's on this switch, so if you don't have an external router, this should point to one of the local addresses.
The default route (0.0.0.0) is used for external connectivity (router to internet)
good luck

Re: HP 5412zl IP Routing problem
1. Your 5412zl is a swouter (switch/router) now.
It doesn't need a default gateway.
To route an ip packet to unknown address it needs a default route via an external router.
To unset the default gateway:
#config
#no ip default-gateway 192.168.249.50
2. In your configuration a default route points to an internal ip address of VLAN 1 (192.168.249.195). It should point to an external router (if any).
Please correct it.
Then try:
#sh ip route
You will see ip routes to all the connected ip interfaces of your VLANs.
Good luck,
Dmitry

Re: HP 5412zl IP Routing problem
either you do the routing between your local VLAN's internally in the switch, or use an external router for this.
However the external router will NOT automatically route between your vlan's as Dimitry suggests. It wil have to be configured for this AND it wil have to know about the used vlan's
As you are still building up knowledge about networks, I would suggest keeping the external router ignorant for most of your network, and continue go the current path using a local router (router funcion built into he switch) for your local subnets.
