Some routers and firewalls allow you to filter on "established"
connections. This feature allows any inbound packets to pass through if
the connection was established internally (outbound) and will overcome
this particular problem. However, it may create other security
problems. I would like to hear from some others about the pit falls of
using this mechanism.
