Hi.
I’m helping in a new network setup which will involve VLANs a switch and the Draytek Vigor 2830. I don’t have the Draytek in front of me right now unfortunately but had a play with the web GUI and configuration. Saw how to set up vlans, assign them to ports and setup DHCP leases etc. However, I’m not quite sure what the “IP Routed Subnet.” Option was for. Can someone explain?

This may well be a very dumb question. Whilst I’m basically a newbie, I do have a decent general understanding of networking. Use Cisco hardware in a lab, VLAns, intervlan routing, router on a stick setub, etc. Maybe it’s a different term for something I’ve overlooked or I need to go back to the books.

Any pointers appreciated.

If it helps. We’ll be setting up 4 VLANs. Only 2 of which need to reach each other. All 4 will likely be Natted to the WAN address. The WLAN will actually be disabled.

Cheers

If you have set up the wan side and just wan 4 internal VLANs you do not need to enable the Iprouted Subnet
This is the same (as far as I know) as the 2nd Subnet feature on older devices.

Thanks. I've left it disabled. Will be deploying it tomorrow.

OK this isn't actually in place yet. Seem to have an odd DNS issue.

I'm connected to the Vigor LAN port 1. 10.100.145.0/29.
DHCP is configured. 10.100.145.1 is the default gateway and DNS for that subnet.
My PC is: 10.100.145.9.

WAN2 is connected to the rest of the ethernet network using 10.20.144.2
The name server configured for WAN2 is the next hop gateway. 10.20.140.1.

However,my PC has been given the DNS address 192.168.0.251. The 192.168.0.0 network isn't being used at all. The Vigor itself can resolve and ping domain names on the internet. I dont understand where this 192.168.0.251 address is coming from. Routed subnet is disabled. I've rebooted and flushed DNS several times.

Any thoughts?

FWIW. I never worked out where 192.168.0.251 was coming from. It's not a DNS address the laptop uses on any network I access. Resolved (no pun intended) by forcing it to use the DHCP server as primary DNS using netsh. All works now.
