 # BEFORE: LOGIN
 # KEYWORD: nojail shutdown
 
+# To use ipv6mon with multiple interfaces, the following additional steps
+# are needed (example with 2 interfaces, em0 and em1):
+# 
+# Copy the %%PREFIX%%/etc/ipv6mon.conf to %%PREFIX%%/etc/ipv6mon-em0.conf and
+# to %%PREFIX%%/etc/ipv6mon-em1.conf
+# In both copied config files adjust 'NetworkInterface' accordingly with em0
+# and em1 and also adjust the 'LockFile' accordingly to
+# /var/run/ipv6mon-em0.pid and /var/run/ipv6mon-em1.pid.
+# Add in /etc/rc.conf the additional line:
+# ipv6mon_interfaces="em0 em1"
