tun0 is created by ppp(8)
in /etc/ppp.conf is:
default:
set log Phase Chat LCP IPCP CCP tun command
set server /var/run/ppp/internet "" 0177
set device PPPoE:rl0
set speed sync
enable lqr echo
set lqrperiod 30
set login
set ctsrts off
add default HISADDR
set timeout 0
set redial 0 0
set cd 5
tun1 is created by OpenVPN with configuration:
client
dev tun1
proto udp
...
so, what can cause the collisions and can i fix them?
