LAN Traffic Extreme Slow..Need Help!!!
« on: June 23, 2011, 09:36:03 pm »
Hi All,

I'm very new to Pfsense.

I'm using PFsense version 1.2.3. After using pfsense proxy. I'm facing extreme Lan traffic slow, latency very high when connect to server. The PFsense server processor & RAM usage very low.

Can somebody please attempt to help me?

Below is my Network Topology


Thank in advance.

Hi,

there is no screenshot of you topology.

What do you mean with "pfsense proxy" ? Do you mean squid ?

PS: If you start new with pfsense, why not starting with pfsense 2.0RC-3 ?

LAN to LAN traffic won't be going through pfSense so that can't be the source of the problem. Try replacing the switch and checking the network traffic to see if one particular PC is causing a problem.
If you're planning on PMing me to ask me to look at a thread, or for individual support, don't.

Cry Havok is right. If the traffic is between PCs on the same subnet then the problem is NOT pfsense.
It could be pfsense if you are routing between different subnets.

LAN to Lan traffic won't be going through pfsense ?
but if i Disable the Pfsense Firewall, my LAN traffic will become more faster..

I Had upgraded to new version 2.0 RC3, but now i cannot use IP address connect to my server, now only can use server name "\\servername"  to connect.....Previously the old version everything working fine....

how to add different subnet to pfsense, so that i can solve the slow traffic & high latency ?

Please provide a diagram showing how your network is configured.  For example:

ADSL --- pfSense (192.168.0.1) --- switch
                                    |  |
                                    |  -- PC (192.168.0.5)
                                    -- Server (192.168.0.10)
If you're planning on PMing me to ask me to look at a thread, or for individual support, don't.

My Diagram as below:

ADSL--Juniper Firewall Rounter(192.168.5.200)--pfsense (192.168.3.2)--Managed switch(192.168.5.10)   
                                                                                                       ||     ||   
                                                                                                       ||     ||
                                                                                                       ||      PC (192.168.3.50)
                                                                                                       ||
                                                                                                     server (192.168.5.50)

fyi--if i put pfsense server in subnet 192.168.5.0/24, i cannot access to local host server (192.168.3.100)...

I can see part of the cause of your problem - you're randomly mixing subnets. If the Juniper has 192.168.5.x for it's internal subnet then you must not use that on the internal subnet for pfSense, and the managed switch.
If you're planning on PMing me to ask me to look at a thread, or for individual support, don't.

For my case. Can you give me example, normally user how to configure it ?


I feel confusion, if i disable the pfsense firewall...the LAN traffic will run more faster.

Please ignore previous Diagram. I had revised the Diagram.

Where is the performance problem? Is it internal to 192.168.3.x, 192.168.5.x or between the 2 subnets? Is pfSense NATing between the networks, or routing? What hardware do you have and what is the volume of traffic (both in terms of bandwidth and packets per second)?

i think is internal problem 192.168.3.x ->192.168.5.x. Because When i open the server share folder, i need to wait for 10 second to open it. If i try to disable the Pfsense firewall, the speed will back to normal (faster).

IF i change the Pfsense LAN IP & my pc IP to 192.168.5.x, example from 192.168.5.x ->192.168.5.x. The speed will like normal, very fast.

I'm using Juniper SSG320M Firewall & HP Procurve Managed Switch.

According to the Status Traffic Graph From Pfsense, In & Out traffic average below 50 Kbps 

Ping Result - From 192.168.3.x to 192.168.5.x
---Reply from 192.168.5.1: bytes=32 time=1ms TTL=64
---Reply from 192.168.5.1: bytes=32 time<1ms TTL=64

So, what you're saying is that the problem is only with Windows file shares? Is the only problem with connecting to the share, or is there also a performance problem when accessing files on the share? Are you connecting by hostname or by IP address?

Also, you forgot to say whether pfSense is only routing or also NATing.
