The config.gateway.json file is included in backups initiated through the web interface and will be reapplied when a backup is restored. That means more research while Untangle is already doing the job. Below is an example of the config.gateway.json file from my lab environment where NAT was disabled on WAN1/ETH2 for a USG-PRO-4. Configure interface IPs. ... we strongly recommend that you disable all NAT traversal technologies including, but not limited to, STUN, ICE, and hard coding external addresses. It would be really nice if they added this as a GUI option. It's also dead simple to put it in 'passive/bridged' mode, where it filters (and measures) everything between my Edgerouter 4 and my LAN. Um das Problem zu lösen, darf das USG nicht auch nochmal NAT machen, also wird diese Funktion deaktiviert. But this router isn’t for the feint of heart. Leider geht das nicht über das Userinterface, sondern über eine Konfigurationsdatei.

This will disable the gateway’s NAT, firewall, and DHCP functions and reduce it to a simple internet modem. Step3. Note: Routing, internet access, and other services may be temporarily disrupted during a provisioning operation. In the process, the source IP address and port of the LAN hosts (Pre-NAT) are translated to the WAN IP address of the router and a random port is assigned (Post-NAT). Many gateways offer these settings, but not all. https://community.ubnt.com/t5/UniFi-Routing-Switching/Guide-to-disabling-NAT-on-USG/td-p/2012460. Might want to look at a netflow collector/analyzer.

First, identify the interface on which Network Address Translation should be disabled. Then you click on NAT and set the start and end port and IP address as explained in the video. Port forwarding on a traditional consumer is as simple as assigning a static internal IP address to a device, then forwarding ports to that IP address. I've been messing with Untangle, and I'm more impressed with its capabilities and insight by the day. You can either restart the USG (which takes time) or simply make a change to the USG (I typically just create a dummy port-forward rule, apply it, provision it and afterwards delete it): Is it, essentially, completely transparent, or would I need to change my network addressing? Seems to be there is no firewall to allow icmp packet to come into USG or no NAT … While some applications set these registry values to disable Teredo when the application is installed, others set them every time the application starts. The following terms are used in the NAT process: Pre NAT Source The source IP address + port of the host on the LAN (192.168.1.10 : 2000 in the example below) before NAT translation. Currently my network looks like: PPPoE connection > pfSense 192.168.0.1 > Netgear switch > NanoHD x 2, Wifi & Wired Devices all under DHCP 192.168.0.2 to 192.168.0.50. Daher haben wir diese Schritt-für-Schritt-Anleitung (einschließlich Video) erstellt, indem wir eine NAT-Regel für ein NAS-Gerät eingerichtet haben, das sich im LAN der USG befindet. Setup on USG ZyWALL: Step1. 1. [*Untangle isn't free; it's $50/year for home/lab use, and that may be offputting, but the the full-featured trial is 14 days, so you can determine if it's worth it]. Create or update a custom config.gateway.json configuration file; Perform a manual device provision of the USG; Create or update a custom config.gateway.json configuration file. As I'm running the controller it seemed that would be an ideal place to monitor this information. Could someone explain to me in simple terms what using a USG with NAT disabled means in terms of networking?

I'm tempted to get a USG for the DPI functionality, but I don't want to stop using pfSense as router. Login. Because all sites are the same IP subnet scheme traffic will not pass through the tunnel. Since the ZyWALL USG-20 has a very similar interface, the instructions below apply to the ZyWALL USG-20 as well. NAT (Network Address Translation) is a technology most commonly used by firewalls and routers to allow multiple devices on a LAN with 'private' IP addresses to share a single public IP address. NAT hat erst mal mit der Firewall und Exposed Host gar nichts zu tun und das macht dann die Fritzbox weiterhin bei Übergabe der Daten ins Internet, nur Doppel-NAT also NAT bei der Fritzbox und am USG kann zu Problemen führen. Deploying NAT-rules on a USG is a very commonly asked request in our support tickets. pfSense does have softflowd and ntopng, but stats of web urls accessed requires squid and I don't want to run that. That's it! New comments cannot be posted and votes cannot be cast. If you are using Cisco phones, you need to disable SIP ALG. Hence, we created this step by step guide (including video) through setting up a NAT-rule towards a NAS-device placed in the USG's LAN.

Firmware 4.4.44 and 4.4.50 have been found to cause potential issues with the NAT mapping over UDP. Currently my network looks like: PPPoE connection > pfSense 192.168.0.1 > Netgear switch > NanoHD x 2, Wifi & Wired Devices all under DHCP 192.168.0.2 to 192.168.0.50. When creating a VPN tunnel between two or more sites with the same IP subnet, an IP conflict occurs. To apply custom changes written to the config.gateway.json file, a manual provisioning operation must be ran from the UniFi web interface. This looks like a bug UniFi Controller which can be ignored. You may need to replace with the site code that you are working with, if not the default site. If your PC has one of these applications installed, make sure you have the most up-to-date version, or see their support documentation to learn how to enable Teredo tunneling with their software.
