Multicast Traffic VPN solution
For remote work I'm currently using Cisco AnyConnect VPN, which allows me to access unicast traffic fine remotely. However, it does not seem to work for multicast traffic. Our multicast traffic is via 29West's LBM (Latency Busters Messaging, now known as "UltraMessaging" (UM) https://ultramessaging.github.io/) and this is not flexible as many of my applications use this and it's not a quick job to change the protocol.
An alternative is to use Windows Remote Desktop Protocol, but my remote bandwidth isn't the best and it feels much slower to move around windows etc. It feels like if we can route multicast traffic through VPN then I can use my applications natively on the remote workstation and it will be ideal.
So wondering if any of you have suggestions on how to get multicast routing to work? Without setting up a remote firewall etc
Multicast is more of a layer 2 thing, where many VPNs want to route layer 3. Yes you could try getting away with routing 224.0.0.0/4 through your VPN, but it makes more sense to NX or RDP into a box that is already setup for your application.
Multicast can be pretty sensitive to asymmetric routing, and requires enabling on every layer 3 hop.
How was your multicast traffic working previously? Same subnet?
