sysutils/ipa from the Ports Collection can do it.
I even can try to write ipa.conf (but didn't test it),
let 100, 200, 300 be IP Firewall rules which counts ingoing
traffic from ISP:
rule isp-ingoing {
ipfw = 100 200 300
info = Ingoing traffic from ISP
maxchunk = 1G
# This allows to monitor traffic before limit 20G.
# limit 10G {
# byte_limit = 10G
# zero_time = +M
# reach {
# exec = /bin/echo "10G reached" | /usr/bin/mail admin
# }
# expire {
# expire_time = 0s
# }
# }
#
# This is 20G/month limit.
limit 20G {
byte_limit = 20G
zero_time = +M
reach {
exec = /sbin/ipfw add 10 deny all from me to my-isp
exec = /bin/echo "20G reached" | /usr/bin/mail admin
}
expire {
expire_time = +M
exec = /sbin/ipfw del 10
exec = /bin/echo "20G reached limit expired" | /usr/bin/mail admin
}
startup {
if_limit_is_reached {
exec = /sbin/ipfw add 10 deny all from me to my-isp
}
}
}
}
I didn't test this config and it can contain errors!
More information in IPA manual pages (also available on
http://ipa-system.sourceforge.net/).
