We have a customer with a network in the 192.168.16.X/24 subnet. They purchased a voip PABX with phones and the company that implemented the hardware put it in it's own subnet using 172.17.0.x/24. They asked us to deliver a router which has a QOS option and a dual WAN option with fallback. My boss decided to buy a Draytek Vigory 2820n as it qualifies.

The problem now is that the voipcompany want to have their PABX available from the internet. So I would need to create a NAT rule (portforwarding) on port 10099 to the PABX with ip 172.17.0.1. My Draytek needs to have IP 192.168.16.9 so how would I make the 172.17.0.x subnet talk to the 192.168.16.x subnet and vice versa. Also, how can I make the PABX use the internet using the draytek?

I don't want to use extra routers. I've read I might use vlans or such but not sure how to make that work. I imagine the following:

All 192.168.16.x ip devices are on a switch, this switch connects to lan port 1 on the vigor
All 172.17.0.x ip devices are on a switch (Power over ethernet switch), this switch connects to lan port 2 on the vigor
The pabx has ip 172.17.0.1
The vigor has ip 192.168.16.9
The vigor has ip Y.Y.Y.Y on wan port 1, this connects to a fiber modem

Now all devices need to able to use the internet. Also I need to forward port 10099 from Y.Y.Y.Y to 172.17.0.1.

Is this possible, if yes how do I configure the router....

Second, I need to configure QOS to have a steady VOIP connection. Never done that before, any guidelines?

i am a cisco guy i dont knew about Draytek Vigory 2820n  may be i give you some general informations
as long as this device has routing capability all devices connected to it should be able to access internet by simply putting the ip address of  Draytek Vigory 2820n port  as defoult gateway
Wait a minute is the 172.17.0.1
 is connected to a (routed port) of  Draytek Vigory 2820n  I mean directly or not ?

good you need an ip such 172.17.0.2 assigned to the voice port (the which you connected voice subnet) and an ip such 198.168.16.1 assigned to the data port of the router .
and enable internet connection loadbalancing Feature on Draytek 2920Vn .

Hi shbasm,

not sure how to assign 172.17.0.2 to port 2... that's the real question. I only have 1 option to set the lan ip as far as I know.

by reviewing the author requirements and reviewing the documentation of the rouer
which the author trying to use i discovered that it is not suitable for him
Because the router Draytek 2920Vn  does not have the capability of Dealing with two
internal subnets so the best solution the  Vigor 3200 Series Router which have such
capability was suggested

HI shbasm,

my apologies for not awarding points. In my opinion my question was 'HOW' can I do it with this router but in fact is was 'CAN' I do it with this router and of so how? So points earned! Thanks for the efforts.
