I think I have a solution (it seems to work!). I'll post it here in case anyone is interested. I wrote these two little scrips: 1. route_up #!/bin/sh set +e if [ $IFACE == "eth0" ]; then # wired table=201 priority=50 elif [ $IFACE == "eth1" ]; then # wireless table=202 priority=100 fi ip rule add priority $priority table $table ip route add default via $IF_GATEWAY dev $IFACE proto static table $table exit 0 ------------------------------------------------- 2. route_down #!/bin/sh set +e if [ $IFACE == "eth0" ]; then # wired table=201 elif [ $IFACE == "eth1" ]; then # wireless table=202 fi ip rule delete table $table exit 0 ----------------------------------------------------- I placed route_up in /etc/network/if-up.d and route_down in /etc/network/if-post-down.d. Because of the differing priorities of the wired and wireless rules, the system always chooses the wired connection when they're both up---all without any manual intervention :-) Thanks for all the replies.
