Adding tailscale to an EdgeRouter (and surviving system upgrades)

I suggest you run sudo bash on all of these so you're the root user.

Installing

1. Download tailscale and put the files in /config/. Find the latest stable or unstable version for your EdgeRouter's processor (ex. ER4 is mips and ERX is mipself)

sudo bash    # if you havent already

luckman212

#!/bin/sh

# set the variable below to your FIOS interface
IF=igb0

/usr/bin/timeout 5m /usr/sbin/tcpdump -ni ${IF} 'icmp6 && ip6[40] == 134' >/tmp/${IF}_RAs.out
FSIZE=$(/usr/bin/stat -f '%z' /tmp/${IF}_RAs.out)
if [ "$FSIZE" -gt 1 ]; then
  echo '<?php include("notices.inc"); $msg = "IPv6 RAs detected on interface '$IF'"; notify_via_smtp($msg);?>' | /usr/local/bin/php -q
