Note: Some Game core configs for Vanilla sources.

Shogun · February 6, 2014

Uhm but what's this for? The vanilla core right?

Mehti · February 7, 2014

Yes. Core configs for vanilla, others freebsd stuff.

Well some suggestions for your script stuff:

Don't do ipfw restart when adding IP bans, this will break all your dynamic rules, e.g. if you have anything like
```
allow tcp from any to me 13001 setup keep-state
```
all your clients will be kicked as the dynamic rules table is flushed and no packets of already open connections will match setup (which is for reason).

Don't just append the rule for an IP ban to the ipfw.rules file with rule number 1, this is dirty and unperformant.

Rather use an IPFW table:

/etc/ipfw.rules:

ipfw add <XXX> deny all from "table(1)" to me ## <XXX> is some rule number smaller than your allow rules
# Load blacklist from file:
while read line
do
    ipfw table 1 add $line
done < /etc/ipfw.blacklist

Ban command:

ipfw table 1 add $ip
echo $ip >> /etc/ipfw.blacklist

Unban command:

ipfw table 1 delete $ip
ipfw table 1 list | awk '{print $1;}' > /etc/ipfw.blacklist ## awk removes the value from ipfw table command output

With this you can even ban whole ranges like e.g. 192.168.0.0/16. Though you cannot remove a single IP out of this range but only the whole range at once.
