PfSense Installtion

Peter_APIIT

I can get the ip from pfsense during live compact disc without connect the wide area network.

Why after installation i no longer can connect to the LAN interfaces and WebGUI ?

The xp saying limited or no connectivity.

I hope you all can help me.

Thanks

Generally "limited or no connectivity" in XP means I can't get an IP address.

So did you setup the DHCP server? if not you either need to set it up or assign your XP PC an IP manualy

PfSense is great but it is probably not a "My first firewall" type thing.
Setting up a good firewall badly won't help you not get hacked.

You seem to be able to surf the net. Fine.
Go and read about IP networks, private subnets and netmasks way before trying to configure your firewall.

Once you do this you will find that all your equipment has to be in the same private subnet with the same netmask. Then you can surf with your XP PC as well. There were at least half a dozen hints in this thread alone you didn't get…

Read and understand basic networking FIRST!

Peter_APIIT

Do i need the DHCP server ? I worried this will weaken the firewall and outside can connect to my network.

I can connect to the internet without pfsense. This is a home network.

Thanks for your help.

Your help is greatly appreciated by me and others.

@Peter_APIIT:

No you can manually assign IPs to every box on the network
@Peter_APIIT:

Not if you don't break the normal setup. Your DHCP server will only respond on the interface you enable it on eg LAN
@Peter_APIIT:

Yes!!! use any home network router you can buy. Most have a firewall and default rules that will work and a support line for you to call and are used to answering the basic questions you keep asking.

Please read all the howstuffworks.com etc stuff on networking it will help (start here http://computer.howstuffworks.com/home-network1.htm )

Is it possible for me don't set up the dhcp server in pfsense and let the router do the job for me ?

The network diagram is as below:
Modem->Pfsense->Router->PC && Laptop.

If i set up the dhcp in pfsense, i need to disable the dhcp server in router, then the problem is how can assign for the laptop ?

Any official pfsense guide to set up dhco server ?

It's become very apparent that you know little to nothing about networking. I would strongly suggest you learn that first, then come back and play with pfSense.

In your diagram each "->" is a separate network, with separate IP ranges. You can run DHCP on each without affecting the other (hint, your pfSense box already gets it's WAN address via DHCP).

As for pfSense related documentation on setting up DHCP servers - if you know basic networking then configuring DHCP is obvious.

Peter_APIIT

I have configure the dhcp server through the pfsense box but still get limited or no connectivity.

I cannot click the system setup wizard during the pfsense live cd.
When i move down, pfsense display different menu.

Please guide me to solve this problem.

Thanks for your help.

Then you need to work out the cause. Without the full picture nobody can help you. If you want help you need to:

Provide an accurate diagram showing how every device is connected
List the network addresses, including subnet, for every network segment
List the host addresses for every interface of every device

If you can't answer any of these questions then you're in far over your head.

There is a well documented problem with using IE with pfSense - use Firefox. Heck, learn how to use the search function of this forum, which is far less complicated than pfSense.

Modem(IP:192.168.100, Gateway:192.168.1.254->pfsense - WAN(DHCP), LAN(10.0.0.1) Subnet Mask:255.0.0.0 -> Router(IP:192.168.1.33, Gateway:192.168.1.1) Subnet Mask:255.255.255.0 -> PC && Laptop.

Do i need to create the /etc/dhcpd.conf ? I think i have start the service.

List the host addresses for every interface of every device.

What u mean here ?

Thanks cry. Your help is greatly appreciated by me and others.

I using Mozilla Firefox in windows box.

I get a tutorial from

http://www.brennan.id.au/10-DHCP_Server.html

# DHCP Server Config File

ddns-update-style none;
ignore client-updates;

lease-file-name "/var/lib/dhcpd/dhcpd.leases";
authoritative;

option domain-name "example.com";
default-lease-time 86400; # 24 hours
max-lease-time 172800; # 48 hours

subnet 192.168.1.0 netmask 255.255.255.0 {
option routers 192.168.1.1;

option netbios-node-type 8;
range 192.168.1.101 192.168.1.200;
}

I don't have the example.com. DO i need a domain name ? Sorry for stupidity.

Thanks for your help.

Peter_APIIT

Why i need a domain name because i did not hosting any web server?

Thanks for your help.

Right, it's pretty obvious you've no clue as to basic networking. I will say once more - learn networking first.

Hint - you're never going to get this working if you make the WAN address of the internal router on a different network from the LAN address of the pfSense host.

@Peter_APIIT:

Configure the service using the GUI. If you're using the command line you're just causing yourself even more problems than you already have.

@Peter_APIIT:

As I said, if you can't answer these questions then you're in too far beyond your current level of knowledge.

Copying a configuration file without knowing what you're doing isn't going to help you. If you want to follow such tutorials then install a standard operating system (BSD, Linux - your choice) and work with that. pfSense is designed to be managed via the GUI only.

I'm going to stop responding to this thread now.

Peter_APIIT

I have found some tutorial but what is your recommendations ?

Thanks for your help.

@Peter_APIIT:

Really, you found 'some' tutorial? Did you study AND understand IT? What was it about?
A possible recommendation for you could be: http://kuali.com/recipes/advresults.asp?c=24
What, you meant something else? OK, go back in this thread and study where others pointed you to already.

Candid camera must be arround somewhere!

Peter_APIIT

The website your send me is about the The Star.

Please send some related link.

Thanks.

I think you already got enough "related links" to study and UNDERSTAND first.

Here are some other links where you can find informations about networking:
http://www.wikipedia.org/
http://www.google.com

If you really are interrested in learning online i can give you here a few questions from our Networking-Test from Chapter1 (Basics of communication) from my University and you try to answer them through online-self-study.
If you can answer all this questions i think you start to understand how a network works on the lower layers.
If you want i can then post the questions to chapter2 (local networks).

Questions:
-01: Name 2 important standardisation bodies and what they do:

-02: What is an "open system"?

-03: What is the difference between a service and a protocoll in the ISO reference model?

-04: Describe the difference between a connection orientated and a connectionless orientated service.

-05: Name all Layers of the ISO reference model and their functions

-06: Explain the difference between a simplex, a half-duplex and a full-duplex connection.

-07: Name 2 advantages of fiber as transfer-media.

-08: What is flow-controll?

-09: What is bitstuffing? What is it used for?

-10: What happens when multiple users use the same medium to transfer data at the same time? What are the solutions to this problem? Name 2 solutions and explain them.

-11: Describe the term "routing"

-12: Explain the difference between "packet switching" and "circuit switching"

-13: What are the names of the layer3 and layer4 protocolls of the internet?

(Hint: the two links above are really usefull to answer these questions)

hi,

i suggest us start by cleaning your pc from trojan and other viruses. then start worrying about your fire wall, if you trojan, i dont think firewall is any good.
