This is what we are trying to achieve:

4 subnets all accessing each other
Internet access on all via WAN1

Hopefully all from 1 LAN port to multiple daisy chained switches

We assume we do not need to use tagging as all subnets need to access each other?

Subnet 1 : 172.16.220.0 with DHCP enabled (for PC's)
Subnet 2 : 172.16.225.0 no DHCP (for static devices)
Subnet 3 : 10.233.183.0 no DHCP (manufacturer static devices)
Subnet 4 : 192.168.1.0 no DHCP (common static devices)

Probably seems strange but at the minute everything sits on the 10.233.183.0 range and is limited by manufacturer to 128 ip's.

So far we have setup and can ping the ip address of the 3300 on each subnet but cannot see other devices on the different subnets?

PLEASE HELP???

I'm no expert on the 3300 but I would have thought that each subnet would need to be on a different LAN port of the 3300 and each LAN port setup as a VLAN, with each VLAN being able to see each other.

That way the Draytek would route all requests accordingly between the LAN ports or via the WAN port for external traffic.

Thanks for the reply RPG, these were my thoughts exactly.

I have now spent a whole afternoon trying to get even the most simple setup working.

Hours on the phone to Draytek premium support. firmware updates, factory resets etc but no further forward.

I have a laptop plugged into lan1 (192.168.1.10) and a laptop plugged into lan3 (192.168.3.10) assigned by DHCP.

Neither will ping each other yet they are visible in the ARP table!

Packet forwarding enabled, all untagged!

I have tried everything I can think of, I don't think it actually works!!!

ANY THOUGHTS?????

I was about to buy 13 of these units but Draytek are being very useless!

Voodle had some suggestions on the 3300 here:

Im starting to regret getting a 3300v

It lacks many features missing on the basic routers and the data sheet and product features dont mention all the farting about needed to perform them
