7004VBR freezing every couple hours

reply to alibaba7
sorry to say that but I believe, there is and there will be never a fix for your kind of problem because the router is/was simply not designed to handle such kind of traffic as emule produces. Ok, some people believe with modding it with a fan or heat-pipe they do help protect the router from overheat and this do the trick but the main problem is and will be that it´s processor and especially the cache are to small to handle hundrets of connections (which many times hang, break, etc. without feedback - which is more a problem of faulty emule design/programming as many people say)

ok I think, an answer like this above, was not what you want to receive so as an small advice which could temp work to lower freeze and reboots with emule do:
- disable min. all the first (on top) SPI function of the firewall or better (but then you are without firewall protection) disable the firewall at all. You still have the NAT-Firewall but not intrusion protection from default firewall rulesets which produce some stress and logging as the firewall believes a lot of the connection-requests are attacks.
- use static-ip´s in your LAN for you client-pc
- use only Virtual Server for port-forwarding and "not" Speciall Applications (or both)
- lower the number of connections (try or find out yourself 250, 200, 150 and lower the number connects at same time to ?)

so, once again, some home-user do stress there router with such kind of file-sharing-progs much more that companys there router. Only my opinion, of course you can have your own but you received what you payed for, something priced 5-10$ after rebate. Enought for simly surfing people, not the right choice for power-user who want to download, play or what ever 24/7

wish you some luck

greetings

First, thank you all for the replies.

Ok here's how I had my router configured.
- SPI/firewall disabled
- static IPs
- virtual servers for emule

Now, following Kinguni's advice I just turned the firewall on (I'm not using rules, just intrusion detection) and MAC filtering. I'll see if that makes the router stable.

BTW Kinguni, what firmware version are you using ?

Thanks again

So I'm using the SMC2804WBR, but it does sound like I might be able to incorporate your solution.

I copied your settings for the Intrusion Detection page, but I'm afraid I don't really understand MAC filter settings. Can you point me to a page that would walk a newbie through how they work?

Thank you.

It's very simple if the pages are the same as for the 7004VBR. From the firewall tab click on MAC Filter. Now, making sure you know the MAC addresses of your computers, enter them on this page. It's easy if your computers get their IP's by DHCP since there is a drop down list at the bottom of the page to copy them into each ID. Make sure MAC address control is set to yes and then click apply.

If I have more time I'll take a look at the manual for your router which should have instructions regardless.

Kinguni:

Are you using PPoE, if so what is your MTU ? I'm asking because the tech support people at SMC told me that lowering the router's MTU setting could help.

I always thought MTU needed to be the same as your ISP's and that most ISPs use 1492... what do you think

I don't think it will help, but you never know. My MTU is at 1492 however, even though my ISP actually recommends 1400, so try lower and see if it helps.

you can try to find the best mtu size yourself with using MS DOS-PROMPT enter:

ping -f -l 1492 www.yourispname.com-net-or-whatever?

ping
-f (f like friend)
-l (l like love)
packetsize (lower from 1492 in steps from 2, 4, 6, 8, 10 or start with something for example 1400 and up it in steps like before until you find the last size which sends packets without getting fragmentated or there will be a range where you get no response because of time-delay)
the name or ip of your internet-service-provider

the max size unfragmentated (for example 1464) + 28 will be the correct mtu size (example: 1464+28=1492 (of course yours can be 1410+28=1438 or what ever you find out) but the maximum for your router will be always 1492 (1500-8)

normaly your lan/client-pc-mtu should be 1500, sometimes it makes sense also to edit this but it inside the registry so for this there are a lot of tools around there in the net which can do editing for you. Change the routers mtu and look if this will resolve the problem before you look at you lan/client-pc-mtu.

Sorry to bump this old thread but I have the VBR and when I entered my MAC address in the MAC filtering section, my computer can't surf the internet. Am I doing something wrong here?

Thanks.

Sounds like you didn't enter the right MAC address. You used the one from your computer, correct? If your computer gets it's IP from the router using DHCP, then it's a simple matter get it.

To be sure, you can go to a command promt (if you are using Windows XP), start, run, cmd, then enter ipconfig /all. The physical address (MAC) of your computer will show up there. Make sure it is correct, and that you haven't mixed up any 0's with O's.

Don't let your computer's idle time go to waste!

Yup, I double checked the MAC address and it's correct.
In the VBR setup menu, It's under the heading "Firewall->Access Control" right?
This is how the menu looks like:
---------------------------------------------------------------------------------- ----------
Access Control
Access Control allows users to block PCs on your network from gaining access to the Internet. The user can block PCs based on IP and MAC address.

Enable Filtering Function [x]yes [ ] no

Normal Filtering Table (up to 10 computers)

(nothing here, says "No Valid Filtering Rule!")

Mac Filtering table (up to 32 computers)
(this is where I enter my MAC address right?)
---------------------------------------------------------------------------------- ----------

Do you want me to PM you my "ipconfig /all" results?

Access Control blocks the listed PC's from the Internet, go instead to Firewall-> MAC Filter for the entries to allow only those listed PC's access to the Internet. Maybe you could not enter the MAC manually but use the entry bar at the bottom of the MAC screen. Select your computer there from the DHCP list and the entry number and click 'copy to' and then click "Apply" and log out.

Make sure you remove the info from the Access Control screen before you log out.

Edit - ok, you probably have the v2 of the vbr with different firmware than above where you get different screens. Don't have that one so....

Ok, I'm such a idiot. I forgot to upgrade my firmware version to 1.23. Now I have the updated router setup menu with MAC filtering.

Thanks for the help guys.

Yeah, the V1.23 is the Stable one, do not try the latest ones, which is designed to fix the Bell South Issue alone.
