When I started using my 2820 a few years ago, I thought it would do routing between the VLANs but I realise now that it won't. I need additional functionality now and, rather than misinterpreting the fact sheets relating to various Draytek products again, I thought it would be sensible to put the scenario here so those who have accomplished this can give me advice about the best way to do it. Alternatively, it may not be possible with ANY Draytek device. I hasten to add I posted a related question in another sub-forum but I haven't received any further responses.
Scenario
There's a main office and a subsidiary, both using Draytek 2820s and ADSL. The main office has VOIP (Mitel) and we'd like to incorporate the remote office into this VOIP network by configuring a VPN, putting a POE switch and 3 or 4 Mitel phones at the remote office. The main office LAN is 192.168.3.0 / 24 which connects to the internet via the Draytek. The VOIP network is 192.168.4.0 / 24 and doesn't touch the Draytek as it doesn't need internet access. The remote office LAN is 192.168.2.0 / 24. We don't need to have a VPN between the sites providing access to resources at this stage, though that might become necessary in due course.
Is there any Draytek equipment that we can install at both ends to allow the main office VOIP to be extended to the remote office? My initial thinking was to configure a VPN between the devices and have the VOIP network attached to the Draytek but have it as a separate VLAN so the Drayteks would pass just the VOIP VLAN traffic between them. Ideally, I'd like to stay with Draytek, rather than move to a different manufacturer.
Thanks for your time.
