Hello all,
I have a VLAN dedicated to iSCSI storage traffic. I have setup the interface just like I would with any other interface. I have no rules assigned for this interface. When I try to ping from one device to another, both in the storage vlan, they do not respond. Do I just need an ICMP rule to allow this to happen? I am trying to troubleshoot some issues.
On a separate but related topic I would like to change the MTU on the storage VLAN to 9000. I assume that every path between any two devices must have their MTUs changed to make this happen correct?
Thanks,
Steve
If both devices are on the same vlan then they should be able to communicate at layer 2 with no firewall in the path. Check your switch configs.
For trouble-free operation, all the hosts on the LAN should have the same MTU and all the connected switch ports should have an equal or larger MTU.
Also for a VLAN dedicated strictly to storage without any traffic to another VLAN or the Internet - why configure on OPNsense at all?
If have this exact configuration, VLAN 8 for iSCSI and NFS between TrueNAS and Proxmox - no VLAN 8 on OPNsense. What for?
I was using OPNsense for DHCP, but you are correct. This is dedicated for storage traffic between my NAS and my client machines. I can just statically assign the IPs and call it a day.
