General Discussion / open port to allow single application to a static IPv4

« on: March 20, 2023, 04:13:15 pm »

Hello

I am required to use an application under Windows7, which sends telemetry-information to a static
IPv4 address over HTTPS and does download some programm-code everytime it's started.

I gave up trying to configure Windows-Firewall for this



Questions:

- is it possible to set such a rule in OPNsense?

- or should I use a personal firewall installed on that Windows machine?

- does it make a difference if I do have a Dualstack or DSlite?



Thank's a lot for your feedback!

Joe


PS
Do not yet have an OPNsense based firewall

Hallo

habe schon interessante Berichte ueber den DNSCrypt Proxy im ct gelesen.

- Ist DNSCrypt Proxy Bestandteil von OPNsense ?

- oder muss eine externe DNSCrypt Proxy Box (zum Beipspiel auf einem Raspi installiert) in OPNsense
  integriert/konfiguriert werden?


Vielen Dank!

Hello forum

Does OPNsense support a second WAN interface (3G, 4G, modembackup) as automatic fallback/take-over
for the case the regular internet connection goes is down?

Thank you!

General Discussion / different FW-profiles for multiboot-machines

« on: November 11, 2020, 02:02:16 pm »

Hello forum

Is it possible to have OPNsense rejected every traffic(on all 7 OSI-layers) if a machine is booted e.g.
with Windows7, meanwhile if the same machine is booted with Linux or Windows10, network/internet-access
should be  granted? How?


Thank's a lot for any feedback!

General Discussion / restrict outgoing traffic per user/application

« on: November 08, 2016, 06:07:03 pm »

Hello Forum

I would like o make sure that no unwanted network communication takes place (mainly from Windows based machines in the network).

Therefore i would like to be asked everytime an application or the Windows-OS itself would like to establish a connection to a remote host/service.


Question:
Does OPNsense already offer such a feature?


Thank you very much!

Joe




PS1:
I understand that such a feature would require an agent on each client(workstation)

PS2:
I do know that some personal firewalls do offer such a feature and as well some very advanced.
