--=-mnwHBEfc3tlWJhlnwJ0v Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable (Apologies for the incorrect post to mailing.freebsd.questions newsgroup :( ) Hello, Occasionally I'm disconnected from my cable ISP (Virginmedia) which is making me wonder whether or not it's my fault most of the time or just occasional 'glitches' with the cable connection. I have a FreeBSD 8.2 firewall/router box (a Pentium 4 2.8GHz PC clone) which has two NICs installed. PF is running on this box. I've recently added the following two rules to my /etc/pf.conf in order to help with DHCP allocations. pass in quick log (all) on $ext_if inet proto tcp from any port 67:68 to any port 67:68 keep state flags S/SA=20 pass in quick log (all) on $ext_if inet proto udp from any port 67:68 to any port 67:68 keep state I have to say that 90% of the time this firewall/router box runs flawlessly. The above DHCP 'additions' to the /etc/pf.conf have only been made today so time will tell whether there's any noticeable difference. Today I had another outage (before the firewall DHCP additions were made) and I got to thinking about how I could restart the network services on my firewall/router box without rebooting the machine itself. After some searching I found the following commands which didn't produce any errors, but I was left with no IP address assigned to my Internet- facing NIC ($ext_if, which is actually 'sis0'). /etc/rc.d/netif restart && /etc/rc.d/routing restart If I reboot this machine it *always* configures the network correctly, providing that there's no problem with the ISP's connection. Does anyone know what I'm doing wrong here ? Are there more or fewer commands needed to simulate the effect a reboot of a FreeBSD 8.2 box would have on general networking ? Should I have included /etc/rc.d/dhclient in the above command line as well ? Thanks for your time. Regards, Pete. --=-mnwHBEfc3tlWJhlnwJ0v Content-Type: application/x-pkcs7-signature; name="smime.p7s" Content-Disposition: attachment; filename="smime.p7s" Content-Transfer-Encoding: base64
