Packet filtering firewall: Linux ipchains implement a packet filtering firewall and can be considered medium security if implemented properly.  A packet filtering firewall looks at each packet individually, it does not (can not) consider any previous packets which may be part of a multiple packet transaction.  In other words, a packet filtering firewall is stateless.
