Hello there,
i need to forward the GRE-protocol to a server in my network, therefore i switched to dd-wrt.

Sadly, after only 12 hours the internet stops working and when i try to open the webinterface, i get the following message: This site is running TeamViewer.

That is all, the rest of the page remains white.

Connecting via telnet led to the error: Connection refused.

Resetting to default settings helps (a simple restart does not help), but i had to enter all the settings manually again. I could not use the backup of my settings as this led to the error again.

Well now it is back online and working - but if it gets buggy within the next hours/days i have to switch back to the stock firmware.

Google did not help - the error message simply seems to have nothing to do with dd-wrt. But i do not even use Teamviewer, so where is that coming from...

What is going on?

Did you forward the proper port to the proper machine? GRE is port 47, what is the build running on it? 15962 is the latest for that unit. Do you have any iptables scripts in use?

I am using build 14896. That was the build that the router database on dd-wrt.com told me to install.

The problem is not related to the pptp-vpn. I just mentioned it as a reason for switching to dd-wrt.

Well, so there is another build available. I will take a look at that.

GRE is not port 47, it is protocol 47. That has nothing to do with port 47.

I cannot find a download for dd-wrt build 15962 for the 1043nd, i am sorry. Where do I have to look for this?

GRE is PROTOCOL 47

That is what i wrote. Maybe you posted shortly after I edited my post.

When I want to download dd-wrt the dd-wrt.com-page tells my to look up my router in the database and there, the new build does not show up.

By the way, i did not have the time to forward GRE, as the problem with the Teamviwer-message occured before I had time to configure that.

I just tried: iptables -t nat -I PREROUTING -p 47 -j DNAT --to 192.168.6.2

and i tried

iptables -t nat -I FORWARD -p 47 -j DNAT --to 192.168.6.2

The IP of the server is 192.168.6.2 of course. This does not work, i get a error message related to the problem with GRE not being forwarded properly. I really do not know much about iptables so the command i used might be wrong.
