Probably, despite what you say about them, preexec/postexec and/or
rootpreexec/rootpostexec are your best bets. You may have to do something
to prevent the clients from disconnecting these shares in the middle of a
session -- there's probably something you can do with policies and whatnot,
but I'm not expert in client configuration.
You could use the logon script, but that would have to trigger something
else that ran the actual iptables script, maybe some daemon could monitor a
socket and wait for some sort of signal to trip off the iptables script?
But then there is no 'logoff' script, and so you would have to use smbstatus
in a cronjob and wait till the user no longer appeared in the list perhaps
to trip the iptables rule change.
Maybe the easiest way to do what you want is to segregate the users by VLAN
-- users allowed to connect to the Internet get put on one VLAN and users
that can't get put another VLAN. Then you only have one rule to rule them
