Re: Firewall + Cable Modem
A firewall set to accept by default has the last rule in the chain as an accept rule. The opposite goes for deny, whereby the last rule is a deny rule (this is the most common way to set up a firewall). The firewall is not the problem. Leave the inetd running, just comment out all the services you don't need in inetd.conf. Do you use ppp to connect to your ISP via a tunnel? Are you using an internal cable modem? Did you try comment out the DHCP line in your rc.conf? Matt.

Some ISP's have very short lease times; and your system may not be quick enough to get a lease. Another option is that you get your first lease before the firewill is fully set up; but that you cannot negotiate a lease after the firewall is there due to it blocking the negotiation process. Temporarily disabling the firewall(and nat) will tell you this. > Jan 25 03:03:00 world dhclient: Listening on BPF/vr0/00:40:33:5a:74:8a > Jan 25 03:03:00 world dhclient: Sending on BPF/vr0/00:40:33:5a:74:8a > Jan 25 03:03:00 world dhclient: Can't bind to dhcp address: Address already > in use This suggest that your dhclient can not bind to the port it needs. You may want to check what is bound to that port. See 'lsof' and 'netstat'. Dw To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message
