NISTNet Network Configuration - Help!

[thel1zardking]

Hello Everyone,

First post here. I recently installed NISTnet on a RHEL 5.3 box after much turmoil and can finally load the module properly. My problem is I am not certain how to configure NISTNet to use two specifc NICs. Is it supposed to automatically see both NICs and route between them accordinly. In my current setup I do not see a delay even when it is added/updated without error to xnistnet. Any assistance would be greatly appreciated.

Setup:
NISTnet
eth0 - 10.X.X.1
eth2 - 10.X.X.2

PC1:
gateway - 10.X.X.1
PC2:
gateway - 10.X.X.2

PC1---->Nistnet(eth0)--Nistnet(eth2)<----PC2

Test:
PC1(ping)-------------------------------------->PC2


Thanks,
LzK

Is forwarding turned on? It is off by default.

cat /proc/sys/net/ipv4/ip_forward

if it says '0' then it isn't turned on. You can turn it on as follows;

echo 1 > /proc/sys/net/ipv4/ip_forward

Thanks, Lazydog that did the trick. My box is now passing traffice between the two machines. Unfortunately when I enable nistnet traffic ceases, not really sure what the deal is there. Thanks again.

I don't know anything about nistnet. But if things are not working check routing would be the first step.
