I am looking at using iptables and have been reading. I have an understanding on how to set up some basic commands to make a firewall but what I have a problem with, is what do I filter?
I don't know what is important (to me) to filter. I know we all need some sort of firewall to protect ourselfs and systems against 'sutff' out there, but just what is that. I suppose one could start with making certain subnets available to myself and deny/reject all others, but I am not sure that is how to go about it.. So - as a general rule, what does one do? What do people block and what do they accept?? -- Ted Gervais Coldbrook, Nova Scotia Canada. 1-902-679-2253
