No default route after returning from PPP connection


Tag: routing,archlinux,pppd

I'm here on a Arch Linux box with a working ETH0 (fixed IP) and PPP connection via 3G USB stick (ttyUSB0). After rebooting, ETH0 works fine. Establishing a PPP connection works fine, too. But after using 'poff' to cancel the PPP connection, I don't get a default route again. I know how to set a default route manually, but as the linux boxes will be enrolled in various networks, I have to find an automated process of getting the default route back after using a PPP connection.

ETH0 was configured in /etc/conf.d/net-conf-eth0:

address   =
netmask   = 24
broadcast =
gateway   =

PPP was setup using

pacman -S ppp

... and the following config files:


/usr/bin/route del default


holdoff 10
maxfail 0

Routing table before a PPP connection:

# route
Kernel IP routing table
Destination     Gateway        Genmask         Flags Metric Ref    Use Iface
default         router.intern         UG    0      0        0 eth0
default         router.intern         UG    1024   0        0 eth0       *        U     0      0        0 eth0
router.intern  *      UH    1024   0        0 eth0

Routing table after a successful PPP connection:

# route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface        *        U     0      0        0 eth0
router.intern   *      UH    1024   0        0 eth0

What am I missing?


To answer my own question: /etc/ppp/ip-down is the clue. (I tried to place a script in /etc/ppp/ip-down.d/, but sometimes it won't get executed. ip-down gets a SIGTERM from pppd too early.) So I modified /etc/ppp/ip-down:

# This script is run by pppd after the connection has ended.

ETH_Gateway=$(/usr/bin/cat /etc/conf.d/net-conf-eth0 | /usr/bin/grep 'gateway' | /usr/bin/grep -oE '[[:digit:]]+\.[[:digit:]]+\.[[:digit:]]+\.[[:digit:]]+')
/usr/bin/route del default
/usr/bin/ip route add default via $ETH_Gateway

# Execute all scripts in /etc/ppp/ip-down.d/
for ipdown in /etc/ppp/ip-down.d/*.sh; do
  if [ -x $ipdown ]; then
    # Parameters: interface-name tty-device speed local-IP-address remote-IP-address ipparam
    $ipdown "[email protected]"


Symfony Controller magic method?
