Time Delay program needed

hi all

I have a small problem with the boot up process of Freebsd and I was wondering if there is a way to slow it down. Here is my scenario... I connect to the internet via pppoe. I have set up rc.conf to automaitically start the internet connection upon booting..Also, I have configured pf firewall on the system to. The problem I have is that since my connection is PPPoE .. pf gets the ip of the computer from tun0. I have also enabled pf in the rc.conf. The problem I have is that in booting .. the pppoe connection takes a bit of time before it completes connecting to my ISP and is granted an ip during which time pf is already loading and looking for that same ip. pf does not load the ruleset until it finds an ip. Is there a way to pause after the system has processed the pppoe enable instructions so that it can establish its internet connection and thus gain an ip in time for pf to start?

Insert "cheap hack" disclaimer here:

put a cronjob in root's crontab with @reboot as the time that runs a shell script which sleeps for 60 seconds or something and then reloads pf.

You could make the script intelligent enough to actually poll the interface every 15 seconds until it's up or something too.

Thanks much for that advice sigsegv, I did figure out a way to get around the problem. If I enclose the interface which is described in pf's ruleset withing "( )" brackets then it makes refrence to the interface rather than search for the ip.... According to pf this is used for DHCP or dial up where the puter has no static address. I was able to apply the same idea to PPPoE thus I made refrence to the interface, and when all the necessary connections were made it used the ip. So that pretty much solved the problem. But, really appreacitate the help. Thanks
