Post subject:  A new way to connect to the dynamips network

I wrote a pseudo interface driver on FreeBSD, which can encapsulate the traffic into UDP packets and send to the destination. So many programs in the real world can talk to the virtual nodes.

Code:
dynamips -i R0 -T 2000 -P 3600 -t 3660 -X --sparse-mem -r 192 -c 0x2102 --idle-pc=0x608599a8 -p 0:NM-1FE-TX -s 0:0:udp:20000:192.168.9.6:30000 c3660.unzip

Awesome. Btw, I am looking to do something similar to support VMware with GNS3/Dynamips. Maybe one day they will include UDP tunneling support into their product...

Cheers,

The UDP tunnel will increase traffic, at least 42 bytes per packet. Does VMware want to do this? The performance is very important feature for VMware.

But it is not hard work, anyway, the vmnet is pseudo interface.
