General Discussion / Planning to use as Internal Segmentation Firewall (ISFW)

« on: July 14, 2018, 02:50:54 pm »

Dear All,
I am planning to use the Opensense firewall as ISFW in my office datacenter. As per basic requirement, I need 40 Gbps speed for "east-west" traffic.  My planning to implement this with 8 vCPU, 16 Gb RAM.

Please guide, will it handle the 40Gbps throughput? I want IPS + Antivirus + Some Basic Firewall Rules. But the most important topic, It will work in Bridge mode.

Regards,
Deepak Kumar

General Discussion / Secondary gateway / Route not working

« on: October 30, 2017, 12:33:57 pm »

Hi Everyone,
I am facing an issue with a route. I am using OPNsense firewall in Bridge mode. My Internal Network (behind the l3 Core Sw) is on 10.10.10.0/24 series and my ISP router to L3 Switch Uplink (Firewall is between of both) are on 10.10.11.0/24 series.
I have added a default route toward to WAN, is working fine. But I have added a static route toward to my L3 Switch and Internal LAN is not working fine.

Firewall routing table is:

root@FO-FIREWALL:~ # netstat -r
Routing tables

Internet:
Destination        Gateway            Flags     Netif Expire
default            10.10.11.1         UGS     bridge0
google-public-dns- 10.10.11.1         UGHS    bridge0

10.10.10.0/24      10.10.11.3         UGS     bridge0

10.10.10.21        10.10.11.3         UGHS    bridge0
10.10.11.0/24      link#7             U       bridge0

10.10.11.2         link#7             UHS         lo0

10.10.11.3         02:14:a0:a5:14:00  UHS     bridge0
localhost          link#4             UH          lo0


When I am trying to my 10.10.10.0 series system then getting the following error:

General Discussion / Secondary gateway not working

« on: September 03, 2017, 09:53:01 pm »

I am using version OPNsense 17.7.1_2-i386 as Bridge mode. My network topology as

(Router 10.10.9.1)-------->OPNSsense (10.10.9.2)------->(L3 Switch)------>10.10.11.0/24
                                                                                   (10.10.9.3)|
                                                                                                    |------>10.10.30.0/24
I have two gateway on firewall
1. 10.10.9.1 (Default)
2. 10.10.9.3
I have added two routes for my internal subnets.

But the gateway which I will be added in the first row is working for all. It does not use my static route for internal vlans.  If I will add the first gateway as 10.10.9.3 (not default gateway marked) then it is working fine but another gateway (default) is not working. 

Please guide me, How I will troubleshoot the issue?

Thanks,
Deepak

« on: July 24, 2017, 09:09:22 pm »

There are many reasons
1. May be IPS mode not enabled
2. May be IPS signature not enabled
3. Right Interface is not selected etc

Please share your network diagram and firewall configurations.
