Aliases allow grouping and naming of IPs, networks, and ports.Option to log or not log traffic matching each rule.Limit simultaneous connections on a per-rule basis.Apart from firewalling and routing platform, you can expand its functionality by using its long list feature it provides without adding bloat and potential security vulnerabilities to the base distribution. This open-source firewall can be installed on a bare-metal hardware machine and can manage entirely via a web interface.
#Untangle firewall open port forwarding software
PfSesne is FreeBSD based open-source software distribution that customized especially to use as a firewall and router.
#Untangle firewall open port forwarding license
There are dozens of open source firewalls available online to download under open source license but out of them the best we would like to recommend are pfSense ( FreeBSD) and ClearOS firewalls.

Why would a port forward rule setup like this still affect/or cause Untangle, which is setup to use 1.1.1.1 and 1.0.0.Linewize: Cloud Managed Open source Firewall for Education Best Open Source Linux Firewall SoftwareĮach of the open-source firewalls we are going to list here offers enterprise-level firewall solutions along with some sets of features that only commercial firewall offers. *if I get rid of the port forward rule all together and just keep the filter rules (it looks like my smart devices with hard coded DNS switch to DoH and start using port 443 for dns without a port forward rule), untangle no longer shows up in the adguard logs. but far far less than it was when setup as above (2k+ entries in a matter of mins vs currently, 39 entries in the past 40ish mins). *though, even setup like this, untangle is still showing up in the AdGuard logs. Using External or Any WAN as a source interface option as setup in my first post, doesn't seem to make the port forward rule affect internal traffic as the smart devices don't show up in the port forward session reports when setup that way. In the end it looks like I have to use the filter rules and then a port forward rule specifically targeting the hard coded dns IPs and forwarding those to the raspberrypi.Īny other way I try to setup the port forward rule, that actually forwards the smart devices, seems to also force Untangle to use the PI as it starts showing up in the AdGuard logs.

Adding Untangle to the source address is NOT doesn't change anything, Untangle still shows up in the AdGuard Home logs now. *Except now this appears to also be forcing Untangle to use the Pi as that box is showing up in the AdGuard Home logs. is NOT External to me would mean that it would look at all other interfaces that weren't External?

Though I am confused as to what Source Address is NOT External was doing since it didn't seem to be affecting any traffic whatsoever (port forwards for 53 were not showing up in the report and looking at natd traffic, devices were still using hard coded dns). With it setup this way I am now seeing smart devices in the Reports > Network > Port Forwarded Sessions log being redirected from their various hardcoded dns to the raspberrypi. Source Interface is internal and the vlans I had to change the port forward rule to: or at least not working how I thought it would. It doesn't seem like the Source Interface is NOT External was doing anything. Devices that use hard coded DNS were still using their hard coded DNS. The pi is/has been working for those devices that properly use what they are given by DHCP. Well, the port forward rule was not working. Queries from the Untangle itself should still use cloudflare like you have on the WAN interface, and these are only queries for our services to connect. These two rules should allow adguard to do any DNS queries and stop anyone from manually changing DNS internally to something like google. Make sure the Adguard rule is above the any non-wan rule. If you want to explicitly block the internal devices from using anything other than adguard for DNS I would make 2 filter rules. I used this setup for a while with a pihole (couldn't keep it because of VPN DNS issues), but while I had it without a PF pihole still did its queries as expected. If you're handing out DHCP you will also want the overrides on any VLAN interfaces as well. As far as I am aware you shouldn't need any PF's in this configuration, as long as you're overriding the DNS in DHCP to push the adguard IP it will query properly.
