Networking conundrum

[mattws]

This is my first post so please be kind!

I'm pretty new to networking so maybe what i'm trying to achieve is wrong and you may say why the hell am I doing that - so please bare with me..
Basically I have a Layer 3 Cisco that i'm using as my Core switch which is trunked/tagged to a Layer 2 HP switch in which some of my VLAN's pass over.
I have ports 1-4 setup for VLAN 10 and have setup the TrueNAS on 10.0.10.10/24 with a gateway of 10.0.10.1 everything working correctly with a failover.
What I am now trying to do is setup iSCSI but using a different subnet. So ports 10-14 are setup on the switch to allow VLAN 20 - 10.0.20.0/24. This work as I can plug in other devices and ping the switch and vice versa.
When setting up a network interface in TrueNAS I am unable to get the link up.. i'm assuming is because I have no gateway set on the interface but for the life of me I can't figure out how to do it?

Any idea's of what the issue could be? It could be blatantly obvious but thus far I've been unable to resolve it..
It could potentially be routing issue from the Cisco but again I am yes to figure it out and any help would be much appreciated!

Thanks,

How many interfaces does your TrueNAS system have? I'm guessing two or more?

Speaking of which... give us your system specs, per the Forum Rules -- the more details you provide, the more likely you'll get helpful responses:

The post below is dated -- it refers to FreeNAS 9.10 -- but it includes a guide for configuring iSCSI (there are probably more current guides here on the forum, but I don't have any links handy):

FreeNAS 9.10 on VMware ESXi 6.0 Guide

This is a guide which will install FreeNAS 9.10 under VMware ESXi and then using ZFS share the storage back to VMware. This is roughly based on Napp-It’s All-In-One design, except that it uses FreeNAS instead of OminOS. This post has had over 160,000 visitors, thousands of people have used this...

Thanks for your reply


True as is being installed on a HP ML30 Gen 9 with 4 x NICs (2 on the ML30 and 2 on a dual port NIC installed on the ML30)

I've had a look on a few guides and they all seem to implement the iSCSI over the same subnet. For example in the guide linked the IP is 10.55.0.x for management and the iSCSi is also using this network.

To keep things simple in my head I want to try and separate the iSCSI network from my management network but when setting a static IP on a second network interface it is unable to communicate with the switch.
I can confirm the switch is configured correctly because I can plug in a laptop setup a static and and get an IP and ping both ways.
