[pfSense] pfSense Implementation with dvSwitch: Urgent Assistance Required

2014-09-30 Thread Rizul khanna
Hello all,


We are trying to use pfsense with dvswitch in our virtual environment,
where we wish to filter traffic to our VMs directly from pfsense. Our VMs
are windows based terminal servers and we want to restrict IPs/ Ports
accessible on them.


Our Mgmt and VM N/W portgroup is the same in the dvportgroup and whenever
while configuring the pfsense machine I connect the pfsense machine’s NIC
to the mgmt-public dvportgroup, the CPU utilization of any of the ESXi
hosts/ all the hosts increases from 5%-60% unexpectedly. We use ESXi 5.5 U1
with single socket Intel Xeon 2690 10 x 2.99 GHz processors on all our ESXi
hosts in the cluster. We have to implement the firewall in the Virtual
Environment, but unable to do so, please suggest something.


I can be contacted on rizulkha...@gmail.com and rizul.kha...@myrealdata.net



Thanks and Regards,

*Rizul Khanna*

Re: [pfSense] Snort as IPS in Pfsense

2014-09-30 Thread Roberto Carna
Ivo, that's a good ideabut please tell me if I'm correct or not:

WAN, LAN, Bridge interfaces: IP-Less
OPT1: IP for management in a management network

Tnaks again,

2014-09-30 9:27 GMT-03:00 Ivo Tonev i...@tonev.pro.br:
 I recommend you create a management network for OPT1 with private IP.

 I think this is good for us:


 - Router ISP with IP 200.0.0.1

 - pFsense with the following interfaces:

   a) WAN IP-Less
   b) LAN IP-Less
   c) OPT1 with IP 200.0.0.2 (management)
   d) Bridge with WAN and LAN interfaces, and Bridge interface IP-Less

 - Corporate firewall with IP 200.0.0.3

 - Snort runs in Bridge interface

 Do you think this is correct ???

 Good night !!!

  I can say that I imagine this addresses space:
 
  Router / IP 200.1.1.1 --- WAN IP-Less / pFsense/ LAN IP-Less ---
  Firewall /
  IP 200.1.1.2
 OPT1 / IP
  200.1.1.3
  (management)
 
  So, the WAN and LAN interfaces from pFsense are IP-LESS (promiscuos
  mode),
  and the OPT1 interface from pFsense has a public IP as router and
  firewall.
 
  Can I do this in pfsense ???

  OK Ivo, this is very helpful to meSuppose I have:

  I have to maintan invariable the addressing of this scenario, so what
  IP
  addresses do I have to assign to WAN and LAN pFsense interfaces ???

  You manage with a browser from LAN, and optional also from the WAN
  port.
  And with ssh from the LAN.

Re: [pfSense] Snort as IPS in Pfsense

you need to use the management network to download.

 Dear, I can't understand at allplease be patient with me :(

 I'll use pFsense with Snort as a IPS because I see is easier than the
 manually configuration of Snort.

 I have an ISP router with 200.1.1.1, a corporate firewall with 200.1.1.2
 and the condition is that I MUST LET THIS CONFIGURATION AS IT IS NOW.

 So, I have to locate the pFsense server between the router and the
 firewall, in inline mode.

 My pFsense server has 3 network interfaces, let's say: WAN connected to
 router, LAN connected to corporate firewall and OPT1 for management with IP
 192.168.1.1.

 Now I have the question:

 How should I have to configure the WAN and LAN interfaces, with IP,
 IP-less, creating a bridging interface IP-less or with IP  Because if I
 create a bridge with WAN and LAN and I don't assign an IP, the IPS won't
 download the signs from Internet...I'm a bit confused.

 Thanks a lot, regards.

 JeLo
