Hi List,<br><br>I am trying to setup a VPN using Shrewsoft. The tunnel seems to come up properly ( no errors), but no traffic passes thru the tunnel. When I use tcpdump, it seems that the traffic is still going thru eth0 and not thru tap0. I have edited sysctl for the rp_filter values, and I do get some errors here, but I don't think it has anything to do with my problem.<br>
<br>sudo sysctl -a | grep rp_filter | grep -v arp<br>[sudo] password for dick: <br>error: "Invalid argument" reading key "fs.binfmt_misc.register"<br>error: "Invalid argument" reading key "dev.parport.parport0.autoprobe"<br>
