#FIREWALL BUILDER INTERFACE BR0 DOES NOT EXIST INSTALL#
So my question would be based on a comment I placed here on your blog over in the section regarding Optware, and that is, if I open my SPI firewall for OpenVPN, then after the install of Optware, not only is port 53 open but also 111, 139 and 445. Not sure of the repercussions of leaving 53 open or what it means but that got even worse when I installed Optware. I did notice that I had to turn the feature SPI firewall off for some reason and I noticed in a Shields Up scan that for some reason port 53 was open on my incoming firewall and I assumed this might have something to do with OpenVPN on dd-wrt. This gave me the ability (through time) learning the basics and doing enought cut and paste to be able to try various iterations of the setup, customizing to my system and at last I finally was successful using 2 "mega" versions of dd-wrt and heavy horsepower routers that supported dd-wrt to build a routed VPN between two family members. Here are the raw iptables rules script as created by Firewall Builder for DD-WRT.Ĭan you recommend a course of study to understand this firewall builder? I have been trying to get OpenVPN working on a couple of dd-wrt enabled routers for about 6 years now (slow learner). Rule 17 will drop everything else not previously allowed in my home firewall. Rules 14,15, and 16 allow the trusted networks to communicate everywhere. Note the guest network can not access the other networks. Rule 13 enables the guest network access to the outside world only. Rule 12 stops all traffic not otherwise allowed to the firewall box. The work VPN disables all local access when the VPN is activated leaves me unable to reach my network printers. Rule 11 allows printing while on a work VPN. Rules 8 through 10 enable the VPN to be accessed from the outside and HTTP for rule 9 which is disabled at this time. Rule 6 lets the router communicate to everything on the network. Rule 4 ensure all trusted networks can access everything needed on the home gateway. FTP is provided so guests can take advantage of the USB Drive attached to the Linksys e3000. Rule 3 gives the guest network access to essential services on the gateway. You can see this done better in Firewall Builder's templates. Rule 2 is sloppy but lets DHCP work on the internal network. Rule 1 enables loopback network communication on the router. Rule 0 adds all internal networks to the Anti-Spoofing Rule. The printing rule is restricted to the VPN Internet exit IP address. The current setup will be disabled anyway for printing seems to have been killed off by the dual monitor setup. This protected data in transit across the internet.

I used an HTTPS URL with Windows XP to print remotely. In the past, I had Apache with SSL reverse proxying to CUPS. I say this is lazy due to having used a much better design in the past. Rule 2 is a lazy rule that enables me to print to my networked laser printer while I work from home logged into the work VPN. The DMZ is off during the summer to keep the DMZ server from running up the electric bill. Rule 1 is disabled but allows access to the DMZ. Rule 0 allows all networks to NAT out to the Internet. So here are my firewall rules built with the help of Firewall Builder.

I got locked out of the desktop software once I setup security to my preferences.

I mentioned on my blog that I have switched to DD-WRT on my Linksys e3000 router mainly because I was frustrated with Cisco's software requiring a Mac or PC in order to make some feature changes.
