If you're using DHCP to get your public IP, Smoothwall doesn't allow you to override the DNS addresses given by your ISP through the DHCP protocol. Time to override Smoothwall :)

Edit /etc/rc.d/rc.updatered, and add "DNSMASQ_DNS1=208.67.222.222" and "DNSMASQ_DNS2=208.67.220.220" at the bottom of the DHCP section, making the file look like this:

#!/bin/sh

. /var/smoothwall/ethernet/settings

if [ "$RED_TYPE" = "DHCP" ]; then
 DNSMASQ_DNS1=`/usr/bin/smoothwall/getdnsfromdhcpc.pl 1`
 DNSMASQ_DNS2=`/usr/bin/smoothwall/getdnsfromdhcpc.pl 2`
 . /var/lib/dhcpc/dhcpcd-${RED_DEV}.info
 echo "$IPADDR" >/var/smoothwall/red/local-ipaddress
 echo "$GATEWAY" >/var/smoothwall/red/remote-ipaddress
 DNSMASQ_DNS1=208.67.222.222                              <------- HERE
 DNSMASQ_DNS2=208.67.220.220                              <------- HERE
elif [ "$RED_TYPE" = "STATIC" ]; then
 DNSMASQ_DNS1=$DNS1
 DNSMASQ_DNS2=$DNS2
 echo "$RED_ADDRESS" >/var/smoothwall/red/local-ipaddress
 echo "$DEFAULT_GATEWAY" >/var/smoothwall/red/remote-ipaddress
fi

echo -n "$RED_DEV" >/var/smoothwall/red/iface
touch /var/smoothwall/red/active
echo "$DNSMASQ_DNS1" >/var/smoothwall/red/dns1
echo "$DNSMASQ_DNS2" >/var/smoothwall/red/dns2

/usr/bin/smoothcom dnsproxyrestart $DNSMASQ_DNS1 $DNSMASQ_DNS2

/usr/bin/smoothcom setxtaccess
/usr/bin/smoothcom setincoming
/usr/bin/smoothcom snortrestart
/usr/bin/smoothcom upnpdrestart
/usr/bin/smoothcom trafficrestart

/usr/bin/smoothwall/setddns.pl
/usr/bin/smoothwall/updatelists.pl

/etc/rc.d/rc.vpn.up
/etc/rc.d/rc.machineregister

The next time you Smoothwall connects, the setting you just put will override the ones from your ISP. Reboot or reconnect to apply.
