Dropping packet: ip_forward is not set

[Nemanja Pavlovic]

Hi,

I am having a problem with packet forwarding from router to router. I get the message that the IP forwarding is not on as you can see in the attachement.
I tried to fix this by enabling routing in Registry settings. I changed IPEnableRouter value from 0 to 1 and that should be enough to turn IP forwarding on. But it doesn't help.

Can you please help me with this? I am using Windows 7.

With regards,
Nemanja Pavlovic from Serbia.

Hi Nemanja,

have you tried this?

Enable IP Forwarding on routers

To enable IP Forwarding on each router, write the value of “1” to the file/proc/sys/net/ipv4/ip_forward. Normally, this would be done using the echo command but Psimulator2 would not accept that command.

To edit the file, use the editor command on each router. On Router 1 and Router 2, enter the command:

# editor /proc/sys/net/ipv4/ip_forward

In the file, delete the number “0” and replace it with the value “1”. Save the file.

That works for Linux. In Windows it can not be done.
Since i last posted here, I installed Ubuntu OS and everything worked fine.
Thanks for this great simulator Stanislav. :)
