Zabbix to monitor site to site links openvpn

rajbps · Feb 9, 2013, 1:31 PM

Hi Team,
I am looking for a solution that will be able to monitor multiple site to site vpn connections.
I seen zabbix and installed the client and proxy but I am a bit lost on how to configure it.

Could anyone kindly advise pls.

Here is the current setup.

Pfsense 2.2

agent and proxy are 2.0

Proxy settings

server:127.0.0.1
server port:10051
hostname:localhost
Mode Active: yes
config frequency:3600

Agent settings

server:192.168.0.31
server Active:192.168.0.31:10050
Hostname:(name of firewall)
Listen IP:0.0.0.0
listen port:10050
refresh active checks:120
timeout:3
buffer send:5
buffer size:100
start agents:3

I have installed Zabbix server on ip 192.168.0.31 but there again still learning it.

Cheers,

Raj

This depends on what you are looking to monitor. The simplest thing I can think of is using setting up an item to uses simple checks icmpping to see if each tunnel endpoint host is responding to pings.

Can you show an example pls if possible.

Cheers,

Could I install zabbix clients on the other end firewalls and get info from those networks, all use pfsense

Cheers,

Raj

Yes, I would install the agent on each machine. The simplest way to check to see if the device is running is by pinging it and I've attached a screenshot of the item. I've added this to the FreeBSD template and linked this template to my pfSense host configuration, since pfsense runs on FreeBSD. If you don't add it to the template, you will have to add it to each individual host.

I am working on a more specific pfSense template now that a 2.0 agent is available but it's far from done. I am open to suggestions on what to add to it.

Hiya,

Thanks for the reply and I hope you could assist me a bit further.

Here is my setup

zabbix server pfsense main firewall pfsense another site
192.168.0.31 192.168.0.251 (Local) 192.168.20.250(local)
192.168.23.251 ( different vlans) this is linked to 192.168.23.0/24 vlan

There are multiple vlans on the main firewall some connection to other remote pfsense firewalls.

So my question is on the remote pfsense, I install the zabbix client.
In the client setting, I will put the following :

server:192.168.20.251
server Active:192.168.20.251:10050
Hostname:(name of firewall)
Listen IP:0.0.0.0
listen port:10050
refresh active checks:120
timeout:3
buffer send:5
buffer size:100
start agents:3

On the main pfsense install the settings for the proxy is :

Proxy settings

server:192.168.0.31
server port:10051
hostname:(Proxyname)
Mode Active: yes
config frequency:3600

On the Zabbix server I created a proxy called (Proxyname) and then added the remote pfsense as a client but I do not get any results.

On the remote pfsense agent logs is as follows:

Do I need any rules on the fiirewall pls.

The link between the remote and main firewall is an openvpn site to site link always on.
