I have an exercise with the Firewall model as shown below.
My problem is not being able to set the IP address (When I set this model, I noticed the lack of a router in the "server area", I thought this was a problem I couldn’t do… Continue reading Set the IP address for the Network model, Firewall Model and Security issue [closed]
I’m currently learning about network security and came across a problem, maybe I’m just missing something obvious but I’ll try to explain my environment:
I have a Kali Linux VM connected to the WAN Interface (192.168.178.109) of a Pfsense … Continue reading scan forwarded ports with OpenVAS/GVM?

The motive for doing this is that I want to open other ports so that I can evade firewalls which block VPN connections. Instead of redirecting eg. port 53 or 123, I could simply set up a destination NAT rule (my router allows ‘easy’ port f… Continue reading Is opening all ports on a router safe if it is simply redirection to a VPN server at 192.168.1.2:51820?
I have a client with IP 192.168.100.95 to which I can connect to with Remote Desktop as long as I am in the same VLAN. If I have a Client in another VLAN with IP 192.168.102.80, I can’t find that client. It works with every other machine I… Continue reading Client only accessible from same VLAN [closed]
