Message 8414 - Posted: 24 Feb 2007, 23:10:53 UTC

I'm using a Netgear WNR834B router since yesterday.
It has an internal firewall and now I can't communicate with following projects:
Einstein@home
lhcathome
QMC@Home
PrimeGrid
Only SETI@home works fine. I can upload work to all project servers but scheduler requests always fail:

Any solution? I tried to deactivate the firewall, but it still did not work.
I think I have to allow access over port 80 for non-http, but it simply doesn't work with that stupid router...

Have you tried one of the schedulers in a web browser? Do you get an error message there too?

BOINC needs only HTTP for that btw., other ports are only needed for GUI and cmdline control.

Does it create sched_reply*.xml files on each contact and - if so - what are their contents?
If they look as expected, it can be a timing problem, I had that when a project server was overloaded.

Have you restarted the computer after installing the router? If BOINC sits in the memory, it might have missed the change in the gateway (otoh. ... it contacts Google so it is not very likely that this is the reason).

Incomplete request received. But that's OK...

The sched_reply*.xml files are created, but they're empty. I can contact all projects when I connect without the router and there's no message that servers are overloaded.

Here another extract from my stdoutdae.txt where you can see PrimeGrid and LHC with different errors, BAM! with error and a successful SETI contact.

I will try a clean deinstallation when I'm out of work next time. Or does anybody have another idea?

Tried clean uninstallation with BOINC folder deletion, but it doesn't work. Only improvement is that I can contact BAM via the BOINC Manager now.

Do you have a firewall on your own PC? Usually router firewalls are pretty basic and don't interfere with outgoing port 80 traffic.

No. Windows 2000 has no internal firewall and I'm not using any third party software firewall.
The crazy thing is, that I can't contact the project servers (except of SETI), even if I place the PC in a DMZ. So it might be a problem with the router's firmware (but it's the up-to-date version), causing the firewall to be enabled although PC is in DMZ, or it's not a firewall problem. But what could it be else? I can reach every corner of the internet with IE via the router, but to connect to the BOINC project servers I need to install a direct connection.

There are quite a few settings in a router. E.g. to get Skype to work i had to set up port forwarding to a specific machine. Here's a website explaining this and that on routers and what to set for many brands: http://www.portforward.com/

Port forwarding is for incoming connections, BOINC only needs outgoing port 80. Incoming 31416 useful if you want to control your client from outside, but that's all.

DMZ is unlikely to help here, but likely to cause security problems on your computer. Stay away from it.

Let's not forget port 443 please, though few projects use it.

Do you know, which projects use that port?
As mentioned before, I can contact SETI, SETI-Beta, and the account manager BAM!, while ABC, LHC, QMC, Einstein, PrimeGrid, Predictor, Spinhenge are unreachable.

WCG is the only I know that uses HTTPS, so using port 443.

Hashbreaker uses the non-standard port 8700.

Remember this is all outgoing.

Are there any ports needed for incoming connections? I spoke to an expert from Netgear today at Cebit, and he could only imagine that BOINC needed some ports forwarded.

BOINC doesn't take *anything* incoming. Servers never send stuff to the clients, the clients ask for it. Then the server sends it back, in the same way a webserver sends you a website or image back to you when you request it.

The only exception is port 31416 for the BOINC Manager to connect to the client. It needs to be forwarded only if you need to administrate your clients remotely (from outside the firewall). I doubt you would do such thing...

I don't know if you can believe it, but I could not at the first sight...
I made a firmware update (manually, because the router didn't find the new version automatically), and it works now.
Thanks for your support, although I finally solved the problem on my own.
