Block connection in firewall -

[Bob Goodwin]

I have been messing with a firewall file 
and added the following:

config rule
         option src              lan
         option src_ip   192.168.1.7
         option dest             wan
         option target   REJECT

It works to prevent internet access from 
that ip. However I can still ping 
8.8.8.8 which leaves wondering if that 
is adequate isolation. Can that be 
improved on?

I have never done anything with iptables 
and I am pushing my skill level in this 
but it is encouraging to have something 
actually work ...

Any suggestions appreciated,

Bob
