I don't think I'm trying to do anything amazing, but IPFW's logging features are giving me a real headache. I can't find much in the archives either, but I find it hard to believe others havne't found this too. My rule: add 100 allow log tcp from any to <my IP> <ports> limit src-addr 2 I want connecting parties to be able to form no more than 2 connection. This works perfectly, jsut as I'd expect it to. Except for 'log'. This rule matches every packet that comes in to the given IP and ports, and as a result, one line is added to the security log per packet. There are a lot of packets. I tried, adding an "add 50 check-state", but that rule doesn't match (the log just carries on logging packets because they match 100), which is very odd. All I want is to have the first packet match of a connection match, like IPF's "log first" capability. Or, better yet, is there a way to format a rule or set of rules, to say "deny if established connections is greater than 2". Logging every one of these packets would be fine.
