Does anybody have any idea about this?  Even on a fresh install pfsense seems to stop showing information from the DHCP logs after a short period.

Ah, thank you very much. I'll have to try this when I get back to the office. I'd do it from home, but I can't get to it from the outside world yet. Guess I forgot to enable that! D'oh! But thank you for your quick response. I can't believe I missed something so simple. Surf Wisely!

Problem turned out to be a broke ass Juniper (Unishpere) Erx that had to have the current DHCP lease cleared.  It would ignore new requests or releases.

Well, your suggestion doesn't work. Adding the invalid .255 IPs to the static leases, I'm getting the following error message in the web interface:     * 192.168.24.255 is inside the range you specified.     * 192.168.25.0 is inside the range you specified.     * 192.168.25.255 is inside the range you specified.     * 192.168.26.0 is inside the range you specified.     * 192.168.26.255 is inside the range you specified.     * 192.168.27.0 is inside the range you specified.     * 192.168.27.255 is inside the range you specified.     * 192.168.28.0 is inside the range you specified.     * 192.168.28.255 is inside the range you specified.     * 192.168.29.0 is inside the range you specified.     * 192.168.29.255 is inside the range you specified.     * 192.168.30.0 is inside the range you specified.     * 192.168.30.255 is inside the range you specified.     * 192.168.31.0 is inside the range you specified. Any other suggestions? My DHCP range is 192.168.24.0-192.168.31.255.

There are only 2 places: Under the general settings where you set the DNS-server for pfSense itself. This is the server the DNS-forwarder will use to resolve external addresses. And on the DHCP-server config-page. This is the DNS-server the clients will recieve.

@GruensFroeschli: You bridged multiple Interfaces to the same "virtual hub". Traffic comes in on one interface and goes out another into the same network. yes GruensFroeschli you are right, i have the same problem and i fix now Traffic comes in on one interface and goes out another into the same network. thanks GruensFroeschli

Update to dnsmasq (2.46) on pfsense 1.2: killall dnsmasq mv /usr/local/sbin/dnsmasq /root/ fetch -o /usr/local/sbin http://rz-home.de/~hhornung/dnsmasq chmod +x /usr/local/sbin/dnsmasq /usr/local/sbin/dnsmasq

We don't use ipfilter, we use pf which has done source port randomization by default for 8 years. ipfilter is finally catching up.  :)

So the rest of the settings do sync though?

No, this isn't a possible solution using DHCP unless you have multiple MAC addresses.

I've seen them support some FreeBSD coding before so who knows :)

System -> General Setup add the two OpenDNS ip's and untick "Allow DNS server list to be overridden by DHCP/PPP on WAN" Then add a static route for each OpenDNS ip, using 1 of them for wan and 1 for wan2.
