Hi,
I'm wondering if the Roamio Plus/Pro can be used as a MOCA bridge for Cisco STBs (set top boxes) that support video on demand? This is a little off the beaten path of anything covered in the 6-options document you typically see on DSL reports although I'm using the "MOCA LAN" option as a rough guide.
I am not a fan of the double-router approach commonly used and fairly resistant to using an Actiontec anywhere in the picture.
Here's my setup:
- FIOS Internet/Cable (ONT connected via the Ethernet port, not Coax)
- Own Firewall Router (not the Verizon issued one)
- Roamio Plus connected via Ethernet but with the "MOCA bridging" option turned on
- Cisco CHS 335HDC P2 Set Top Box (for PPV/VOD) which only works on MOCA (Ethernet is disabled)
This configuration *almost* works for me. The STB will boot up and DHCP across the Tivo and get an IP address from the router. I've assigned it to X.X.X.200 for STB and X.X.X.201 for the Cable Card(?) which should be high enough to work. It's able to download the programming guide and functions like Caller ID work seamlessly.
The *only* problem is the Video-On-Demand doesn't work properly. It will take me to a black screen, report an error, and suggests I reboot the non-existent Actiontec router.
I don't know if the problem is a port forwarding I'm missing or if the Tivo Ethernet-to-MOCA bridge just won't handle this type of configuration (maybe doesn't forward multicast, maybe too high a UDP packet rate, etc, etc?)
I'd really like to understand what the STB needs to do that's special for VOD.
My firewall shows a few interesting items:
- There is significant UDP traffic to and from the STB (port 31430) which appears to be routing when attempting VOD
- I also see some reports of dropped UDP packets from the firewall
- I see an outbound TCP connection from STB port 48840 dropped with TCP Flag "RST"
- I see an outbound ICMP message from the STB to the Verizon remote address
- There is traffic from a Verizon IP to the multicast group 224.0.0.1 (port 17, protocol 2)
My questions:
1) Is anyone successfully done this style of LAN-to-MOCA bridge behind a standard firewall (Cisco, Juniper, iptables, etc)? The ports commonly mentioned in the setup for firewalls don't match what I'm seeing from my STB experience.
2) Does it make sense this would even work over a Tivo MOCA? Any good way to test?
3) Is anything special like PnP, multicast routing, ICMP, or some other setting necessary?
Verizon obviously doesn't support this type of configuration and hasn't published much on debugging when a non-standard setup doesn't work. But I'm so close I feel it's probably possible.
