Re: [Bluez-users] pand, bnep0 and no traffic flow

[Andy <andy@thebmwz3.co.uk>]

Thanks for the hint Frederic, but yep its allowing ICMP ping's as it 
does on all other interfaces.

cat /proc/sys/net/ipv4/icmp_echo_ignore_all
0

(I also try SSH and HTTP to be sure and nothing passes the bluetooth link)

Regards,
