I'm not familiar with Tomato - does it show individual port traffic? DD-WRT has 4 bandwidth graphs, WAN, LAN, Wireless 0 (g in my case), Wireless 1 (n in my case).
My GG is on a DECA in the basement at the Swim16 / splitters and is bridged to the LAN via the 34 back to the router, so without re-configuring, I can't see the DVR to GG traffic.
But in downloading or streaming a program to my wireless Laptop (N-Band), I see the traffic on the W1 graph, but not on the LAN graph.
The LAN graph pretty much tracks the WAN graph so I have to conclude the LAN graph is only showing routed traffic even though the download passes through the router.
Can you identify other traffic (file transfer, video stream) on the LAN reporting?
I'd guess that you should see MRV traffic just like a stream from the DVR to GG.
Tomato (ver. 1.28 by Shibby) has a real time "Bandwidth" graph similar to the one you describe for DD-WRT, but list the options as;
vlan2 = WAN traffic (internet)
eth 1 = 2.4 GHz WiFi traffic
eth 2 = 5 GHz WiFi traffic (not being used on my network right now)
br0 = LAN + all WiFi traffic from both radio bands
eth0 = LAN + WAN traffic
vlan 1 = LAN traffic
NOTE: ("eth" means "ethernet," "br" for "bridge," "vlan" for "virtual local area network" of course)
It also has an "IP Traffic" monitor which graphs the aggregate (from all ports I assume) data traffic rates to or from any IP host on the network.
And this is the graph I was using to try and monitor the GG during a show's preparation stage and don't see much to speak of.
However, as was pointed out originally be Stuart, as a consequence Tomato's IP TM simply may be missing these very narrow duration pulses of IP data sent at hi speed from the DVRs to the GG during the preparation phase of a program.
