ip tables

Any way to have IP tables always allow itself (its IP address) without having to change the
table every time you change a machine's IP address?  Besides 127.0.0.1 that is, because,
say a machine is 10.0.0.80.  If 10.0.0.80 is not in IP tables, then you can still send if you send
to 127.0.0.1 but not if you send, as we sometimes have to, from 10.0.0.80 to 10.0.0.80.
If you put 10.0.0.80 and then change the IP address you have to change IP table.
