The ipfw ruleset would still help though. I'm not sure that Maxim (a person who got the problem) can publish his rules. But as i know there is a typical firewall-script (`ipfw -f flush` and a lot of other rules). As i see in the code, panic is in the line 2538: if (set_disable & (1 << f->set) ) continue; I think panic here can be only when "f" is invalid. I'm right? But it seems protected with IPFW_RLOCK... -- WBR, Andrey V. Elsukov
