IPTables question

[Mike Ballon]

When listing try iptables -L -n

also you should see a port, ex:

ACCEPT     tcp  --  10.0.0.0/8           0.0.0.0/0           state NEW tcp
dpt:22

or in your case I'm guessing ici is the protocol and you grep ici from
/etc/services you'll see port 2200

I would just use the IP on the rule unless you have a reason not to.
