Enabling Internet Access to Voice VLAN

[pmcbride]

What is going to be the easiest way to grant internet access to Voice VLAN on a Cisco 9200L?

[pieterh]

the same as for any other vlan!
- enable routing for the subnet used on the vlan
- add this subnet in the NAT rules or access-list on the router/firewall facing the internet
- add this subnet to the access-list allowing internet acccess

but why do you need this ? what specific access do you need?
do you have hosts on this vlan that need to  access the internet ?
or do you need your phone/video devices to access the internet directly ?

Site is pushing out a VOIP paging solution that requires multicasting. Multicast Design Considerations and Troubleshooting

[Elliot Dierksen]

Unless you are using a cloud version of Informacast, internet access isn't required. Multicast routing routing is absolutely required. That means enabling IP multicast routing on EVERY routing device that paging could traverse, and enabling PIM on all the Vlan's where phones/speakers will reside. The Informacast docs are pretty good, IMHO.

Ah, well as the vendor documentation describes, you'll need to configure multicast on the LANs, but as you also mention Internet, if that's for site-to-site for this multicast app, you'll either need to tunnel across the Internet or use vendor gateways.

If there's already site-to-site connectivity you might be able to leverage it.

BTW, VoIP apps are often the leading example of needing QoS, which can be problematic across the Internet (although there are a couple of techniques that can be used that VoIP SLAs can often be achieved even across the Internet).
