QOS Question on DD-WRT V23

    When setting up the options for QOS, there is obviously the ability to set up priority for more than one application or device in the setup. My only concern and need for QOS is for VOIP.

    There is a choice to prioritize the physical ports, MAC Address, IP address, or application. 1st question is; has any of the 4 proven to be better at bandwidth management than the other 3; i.e. is choosing IP address of VOIP adapter better than doing MAC Address of adapter?

    2nd question. While the application, IP address, and MAC Address methods can be disabled by not having anything inputted, the physical port option CAN'T be "NOT USED". Does this mean that if ANY OTHER OPTION; i.e. IP address, MAC Address, or application HAS AN OPTION INPUTTED, that the physical port option is overlooked??? OR, if I have the physical port set to bulk or standard but the IP address or MAC address of the voip adapter in that physical port is set for premium; is the priority premium or what the physical port is set at???

    3rd question is; Of all the DD-WRT users here, do you think that this firmware has the best QOS functionality compared to Thibor, Talisman, OEM Linksys, etc... I know the DD-WRT forum will be biased. and that's OK, but some of you may have chosen this firmware for other reasons and don't care about the QOS and therefore may be more objective.

    I have a WRT54GS V1.0 . The damn thing is indestructable. Except for some simple port forwarding for an IP Cam and the VOIP adapter, the linksys is a basic DHCP/Switch?Wireless setup for 5 PC's, 1 VOIP adapter, and the 1 IP Cam. Almost ANY ROUTER/SWITCH can do this job. The most important thing to me is QOS. Obviously I can't tell the family to get off the computer every time a call comes in. For that, I could have stayed on dialup. LOL!!! At the same time, I can't have the wife bitching because the phone call is choppy while I am still surfing. So, any assistance will be greatly appreciated. Thx... Mike...

    I am using WRT54GL and bought it specialy for doing QoS for VOIP.
    I found that setting VOIP adapther MAC to PREMIUM priority and setting EMULE MAC address to BULK working very well. I tried to use L7 filters w/o any success.

    Use MAC since you wont have to reset it when you change ports or add on, and the ip can also change. and dd-wrt is IMHO the best third party firmware there is.

    the few bugs that do get in are fixed promptly and the interface is very configurable and easy to use.

    Thanks for the inputs. IP addresses will never change in my world, so that isn't a problem. I brought up the choice of IP or MAC because in some of the linksys firmwares people said they actually had problems with one or the other, can't remember, and they recommended the other.

    I wouldn't prioritize the port, but my question for that was if I prioritise based on the IP or the MAC address, doe that overide the port settings??? i.e. if I leave all the ports at standard or bulk, and I have QOS prioritized by MAC for premium, but obviously it is physically in a port, with the MAC QOS premium overide the port bulk setting. Thx... Mike....

    I think port settings are not working in WRT54GL. At least they are not working for me.

    As far as I know, port priority never worked before; however, just in case, I would suggest that you disable all four of them.

    As per BrainSlayer (and I have updated the WIKI with this):

    Ethernet Port Priority only works on older, ADM based, chipsets.

    That is, the Linksys WRT54G v1.0, 1.1, 2.0 and the WRT54GS v1.0.

    Thanks... I DO HAVE a WRT54GS Version 1.0 . The port priority IS selectable and CAN NOT be disabled. On the OEM version of firmware, it said that port priority ONLY took affect is NO OTHER priority was selected; e.g. MAC, IP, Application. If any of those were selected, then supposedly it didn't matter what the port's priority was set at.

    So, the question is; is that the same rule. I can't UNSELECT PORTS. That option isn't available. So, If I choose to prioritize by IP address to the highest, does it matter if the port that that device is plugged into says something different? See my dilemma? Thanks... Mike...
