Re: [Discuss-gnuradio] Tunnel.py with USRP x310

[Julian Arnold]

Hi Danilo,

Normally you would have one USRP attached to one PC and another USRP attached 
to a second PC.
No switch needed. Then, you can use the Tun/Tap interfaces created by tunnel.py 
to communicate between the PCs.
You will need to set an IP address for each Tun/Tap interface once they have 
been created by tunnel.py.
Just pick a separate subnet for the tunnel IPs as compared to the USRP IPs.
For example, the USRPs could both have 192.168.0.1 and the PCs could both have 
192.168.0.2 on the Ethernet interface which connects to the USRPs (assuming no 
switch here). After starting tunnel.py on both PCs you can set the IP of one 
tun/tap interface to 10.0.0.1 and to 10.0.0.2 on the other.

Hope that helps.

Cheers,
Julian
