But what should I do if the server machine in question is the router itself running on OpenWrt? I can think of two options. The questions are: Am I right to think these are the two options I may consider? What would be the pros and cons on either side?
To get your answer, simply backup the config, erase the router and see the setting. I honestly don't have a device in default configuration to check for you. As usual, thank you for the prompt an accurate info, lleachii. I did read the firewall article, but did not understand all of it. I can verify that the default is in fact captured in the image above. Thanks for the very nice summary. Loving LEDE so far. Not sure what to believe. As far as I know, the circled option is for determining if traffic is forwarded between different subnets inside this firewall zone.
That is, I had a separate wireless and wired subnets, but both inside the firewall zone called LAN. They could not talk to each other by default until I chose "accept" there. I mean, the installed base is most probably divided into three camps: Those 1 who know nothing about the settings and leave them as they are, those 2 who suffer under a misconception or many and wonder why changing settings has unexpected or inexplicable results and 3 the very small minority who have tried every combination and figured out what does what and what goes where and 4 the even smaller minority that somehow knows the theory behind the firewall and really knows how one forward is different from another forward.
I have to get off-topic to say that Google isn't anybody's friend other then big data and big data affiliates. Wiki is explaining it quite well in my opinion. I saw no explanation there that would have answered my question. I don't know about the original poster's question, but I see there are answers to it that even add to the confusion.
Name Type Required Default Description enabled boolean no 1 Allows to disable the declaration of the ipset without the need to delete the section. If the external option is unset, the firewall will create the ipset on start and destroy it on stop.
Only applicable to storage types hash and list , the bitmap type implies ipv4. In most cases the storage method can be automatically inferred from the datatype combination but in some cases multiple choices are possible e.

Since custom iptables rules are meant to be more specific than the generic ones, you must make sure to use -I insert , instead of -A append , so that the rules appear before the default rules. If the rule exists in iptables, it will not be re-added. A standard iptables -I or -A will add a duplicate rule. This website uses cookies.

In this article we will use the firewall placement between an external network and two internal networks as an example to demonstrate the deployment of OpenWrt firewall on Sunlight.
Access the dashboard of OpenWrt firewall. The default settings would allow the user to access the dashboard from the network in the LAN zone. Configure the networks attached to the OpenWrt firewall instance to be the correct interfaces under OpenWrt configuration. Configure the interfaces in the OpenWrt firewall instance to be within the desired network zones for firewall purpose. In the scenarios illustrated in this article, the network "private network 1" and "private network 2" can access the "Physical NIC 0", so the basic firewall configurations are as follows.
