Inquiry "Port forward, DMZ"
- 
 Hello Guys, 
 I HAVE SOME QUESTIONS, PLEASE EXPLAIN THE STEPS IN THE RESPONSES.
 NB.: I USE Pfsense Ver. 2.4.4-P3 AMD AND ESXI 6.71- I created a role to open Port 1194, following this explanation: https://www.informaticar.net/create-port-forwarding-on-pfsense/ 
 ** It did not work and appears to be closed on a site: https://portchecker.co/
 2- I have a web app that is run from outside the network, before using Pfsense I open NAT-DMZ on the router from WAN to local IP. Now I can't open this app. 
 ** I also followed this explanation, but I could not add the third network card, I not found add button:

 3- I have a program that does not work in the domain environment, and after installing the Pfsense and active DHCP, I found value in details for ethernet: connection-specific dns suffix get domain I add in general like "computername.local" I try remove domain name from Pfsense but is mandatory. and the employee can't open this program now

 Hi, - No need to go to http//whatever.on.the.internet.tld
 Like Mercedes knows all about Mercedes cars, Netgate/pfSense knows all about pfSense : https://docs.netgate.com/pfsense/en/latest/nat/port-forward-troubleshooting.html
 I would open my tool box, that is : clicking on " Diagnostics > Packet Capture" and set up for a capture on port 1194 and UDP (?) and start it. 
 Then, try to connect using your remote App.
 Stop the capture.
 Look at the result : something came actually into on your WAN (?) NIC on this 1194 port ?
 If not : the problem is up stream : traffic didn't make it to pfSense.Read the entire check list on the trouble shooting page : execute every step, and if you do not understand : ask. - 
"before using Pfsense I open NAT-DMZ on the router from WAN to local IP. " pfSEnse is not any different from any other router on planet Earth. 
 You have to create a NAT rule, using incoming port, outgoing (destination) port, a 'LAN' (DMZ) IP address and that's it.
 But if 1) applies, and nothing comes in ... well yeah .... 1 explains 2.
- 
"I have a program that does not work in the domain environmen" : I don't understand. 
 That's a typical user that describes an error.
 Your are the network admin ? Start detailing what actually happens. We, from here, know nothing about your network / needs / setup.
 Give details and we figure it out.
