My router is Newifi D2 which has 512MiB of RAM, which is plenty.
Right now I have ~120 users, mostly wireless clients with light network usage. The Active Connections is around 7000. In the next few days, I shall merge another Wi-Fi system into this, and shall likely have ~300 users. More wired clients are planned.
It is likely that the maximum net.nf_conntrack_max of 16384 will be reached in no time. What should I do to increase that limit?
And can I limit the maximum connections per network device? I want to prevent bad guys from torrenting and bring the whole network down.
Why does it even work? From the look of the extension, it looks much like a configuration file. But I can see it is parsed as shell script. Can I put arbitrary code inside it?
