[nos-bbs] Duplicate input?

[Lakenet]

I'm running JNOS 2.0h under Ubuntu 8.04. I'm not strong in Linux but have 
self learned enough to compile and run JNOS. I believe everything is working 
fine but have one question. Ampernet traffic is coming in the encap port and 
working fine. The same information is coming in the tun0 port and JNOS 
responds unreachable port returned. This duplicate information does not 
appear to cause a problem or affect bandwidth much. Is there some 
configuration I need to avoid the tun0 traffic? Or is this the same traffic 
showing up on both ports on the monitor and is normal?

Thank you,

Jerry, N0MR
