Sometimes it may be necessary to clean up existing firewall settings so you can redo them from scratch.  Here’s some helpful steps courtesy of Vivek Gite.

Note: This applies to Redhat, Fedora, and Cent OS

# service iptables save
# service iptables stop
# chkconfig iptables off

If you are using any other disro type the following command to clear up firewall rules:
# iptables -F
# iptables -X
# iptables -t nat -F
# iptables -t nat -X
# iptables -t mangle -F
# iptables -t mangle -X
# iptables -P INPUT ACCEPT
# iptables -P OUTPUT ACCEPT

Thanks Vivek!

It’s sad to say I don’t use the vi search & replace enough to have it ingrained where it should be, so here’s to open documentation:

Adding the “how to” search for those who might need it:

Note: Search wraps around at end of file

To search STR forward: /STR
To search STR backwards: ?STR

To repeat the search: n
To repeat search in opposite direction: N ([SHIFT]-n)

Replace
Replace: Same as with sed, Replace OLD with NEW:

First occurrence on current line: :s/OLD/NEW
Globally (all) on current line: :s/OLD/NEW/g
Between two line numbers #,#: :#,#s/OLD/NEW/g
Every occurrence in file: :%s/OLD/NEW/g
