Dear all,

My questions relates to a Draytek Vigor 2820Vn.

I want to run 3 private subnets:
192.168.1.0/24
192.168.2.0/24
192.168.3.0/24

Using the VLAN functionality. Each VLAN will map to a different subnet.

However, my question specially relates to NAT. Is it possible to NAT each of these internal subnets to a single public IP address.

Is this functionality configured using the 'NAT - Address Mapping' function?

Thankyou for your time.

That's really not going to work I think, most of the draytek routers only do one NAT subnet. NAT - Address mapping is for forcing local IP addresses / ranges to use a specified public IP address
The 3300 series can do up to 4 though and has full 802.1Q VLAN tag support
