2 clients to connect to each other
-
@gertjan
I use both sir, I also ask which one is better than the network interface that I show -
@ezvink At a loss to what your asking.
If you have client A on Lan 192.168.15/24, and B on OptX 172.16.120/24 and you want to let B talk to lan, then you need rules on interface OptX to allow that
Looking at your vms, one is a pfsense with 4 different network connections, and then test with 3 connections.
If test is your client and you want this in your optX network, then it should only have 1 connection.
And on your pfsense do not understand why you would connect it to the virtualbox host only network?
Also your bridging some wifi adapter on your host? This more than likely going to be problematic in its own right.
-
The VBox 'bridge' interface type to wifi should be fine. It doesn't really care what the host NIC is.
However I would certainly use an Ethernet NIC on a VM host given the choice.As I read that the two examples given are both VMs to be used for pfSense and you are asking which would be better?
The answer there is they are both the same in a network topology view. One has the host-only adapter which, as we discussed at length, you don't need. But the only difference that makes is that because it's probably the LAN interface it has pass rules by default and no other interface does.
You need to add pass rules to the other interface(s) as described here.

Quite possible currently - but I do remember from back in the day that bridging a wifi adapter could have issues.. Depending on the nic, I believe some of the broadcom work, but I think they were doing something with arp-nat..
I haven't had to do any sort of bridging with wifi nics in really long time, but do recall depending on the actual nic, and drivers there could be problems with it.
I would use a wire on the host to get to the network.
-
Mmm, you could be right. I ran across a laptop running VBox in Windows that was doing exactly that quite recently and it worked. But I don't recall what the wifi hardware was. That might explain the difficulties connecting to the WAN via the bridge we saw previously.

@stephenw10 yeah like I said its be a coons age ;) since I have done anything with bridging wifi adapters.. But I do recall if all the stars were not aligned it was a big PITA, etc.
But many a moon ago I gave up all that nonsense and use a wire on anything that has a wire, and only thing that does wifi is APs (designed to do it) and mobile devices (phones/tablets) designed to use wifi.
Anything else has a wire.. My TV has a wifi adapter in it - and to be honest wifi prob be faster since its only 100mbps interface (cheap is the only reason these days).. But its a 55" tv - so its not like it moves so wire it is ;)
While working at home my laptop - again wired, because I am not moving about with it - its in my office where I work, so again wired! ;) Don't get me wrong I love wifi when its appropriate - but using a wire when you can sure cuts down on a lot of bs that can come from wifi ;)
-
[Off-topic] Yup, it kills me that I have wifi connected thermostats. They are screwed to the wall and always on the end of a wire.
-
@stephenw10 yeah same here.. Whats funny with mine is runs wire from the thermostat runs into the closet where the furnace is - and there it goes to a device on the wall that connects to my wifi.. Wish I could just plug a wire into that little box ;)
Just so stupid - its not like that is ever going to move about.. Your talking pennies to add a ethernet port, 10mbps would be all it needs..

@johnpoz
I want the attacker to be able to access the web server, sir, therefore the PC web server and the Attacker must be connected first, right?in a VM whose network interface has 3 interfaces, the pfsense web gui is accessed by the PC web server pak, therefore I think that I should add 1 more interface to control the web gui.
can you tell me what kind of rules so that what I want can happen? because I'm already confused, sir, looking at the video on YouTube it always can't run on my VM.
-
It's a VM : with a few clicks you can add a 4th interface.
Then start the VM, use the console access of the VM-pfSense to assign the interface to pfSense.
Connect to LAN inyterface, assign a pass-all firewall rule as mentioned earlier on the 4th interface.
You're done.Btw : yes, things will be way easier if you do not use a VM, but a bare bone PC, and a quad NIC Ethernet ports.

Have already stated this, any any rule would allow all access.. Just like the default lan rule.
-
@gertjan
so basically I just need to set up the LAN interface to add pass rules to all interfaces? like that sir? -
By default, when you install pfSense, and assigned a LAN (and a WAN) interface, the LAN interface has already the correct "pas-all" firewall rule.
On every other OPT1, OPT2 etc interface you create afterwards you need to create the same rule. -

The default lan rule already allows this.. What you need to do is setup the rule(s) you want on your new interface..
By default the lan interface has any any rule out of the box, when you create a new interface be it native or vlan there will be no rules on it. If you want devices on this network to be able to go anywhere you need to create rules to allow what you want, if you want devices on this network to be able to talk to any port/protocol on a device in lan - this would be a any any rule..
Just like the default lan rule.
Example - here is another interface on my pfsense, any client on this network can go anywhere they want, internet, my other networks, etc..
What rules you create is up to you, on what you want to allow or block.. But if there is no rules, then you can not go anywhere, default deny.
-
thank you sir, because the advice you gave I have done and it worked.
but if i add snort/suricata to pfsense and i will try to hack client IP 192.168.19.1 will the alert of hacking will appear in dipfsense?
-
@ezvink
If the 'hack' is matched by a rule set used by snort ( or surricata ) then yes. -
I've tried to hack into the webserver IP which is 192.168.20.5 while the one listed on pfsense is the webserver interface IP is 192.168.20.1, does that matter? because every time I hack the IP of the web server 192.168.20.5 it is not detected by suricata/snort
-
@ezvink From where - if your on the same network pfsense never sees that traffic.
If your using IPS, what do you have it running on what interfaces, what rules are you using in the IPS? As mentioned it can only detect what it has signatures for, etc.
What "hack" are you doing?
-
@johnpoz
IP webserver and Attacker are different sir.I added DDOS,ICMP,etc rules sir
I tried to do DDOS to the web server but it was not detected by Snort/Suricata.
I mean is it possible that the IP I'm supposed to be hacking is the IP listed on pfsense? but I've also added DHCP Server to the IP of the webserver pak and the host of the webserver gets the IP 192.168.20.5 while the IP listed in pfsense is 192.168.20.1.
Even when I did Nmap it wasn't detected, even though I managed to do the Nmap. -
@ezvink again what interface do you have IPS listening on? What specific rule(s) specific, what attack specific.. What specific dos attack did you send, 1 box isn't going to send a DDOS.. Could send some specific DOS attack, but not a ddos.. the first d stands for distributed.. Which normally means a volumetric sort of attack by flooding traffic.
Where are you attacking from? In your first drawing your list 172.168.120.1 as attacker and webserver at 192.168.15.1
So you have your IPS on intrnet2 in your drawing?
If you have your networks setup and talking to each other now, and you want to ask other users of ips/ids how to "test" it and use it prob better off starting a thread in the ips/ids section of the forum
