PFSense cant connect LAN to internet (Newbie)

[chow04]

Hi,

Im a newbie here so please be considerate when it comes to technical terms.. ;)

To start with my problem this is my connection.. ISP -> Modem -> PFSense 2.0.2(Serves as a firewall and router) -> Switch -> PC

ISP - Static IP which is /30
LAN - Static IP which is /24

IP Addresses:
ISP: 103.21.. /30
GW: 103.21.. /30
DNS (Provided by the ISP)

PC: 192.168.3.2 /24
GW: 192.168.3.1 /24

The problem is i cant access the internet in my PC all i can do is ping my ISP IP, PC and PCGW.
I try to check the status of the GW of my ISP on the GUI and it is offline and also ping the DNS which is unreachable host.

Can someone please explain to me and elaborate on what to do? this is my first time to use this and want to try it out.

Thanks

Can you connect to the pfSense box from your LAN client?

Can you ping the ISP gateway from the pfSense box?
Is it showing the WAN connection as down on the dashboard? Edit: I see you've already said this is the case.

Your ISPs gateway may not respond to pings. If that is the case pfSense will mark it as 'down' and stop sending traffic to it. You will need to change the monitor IP to something that does respond to pings or disable link monitoring.

A couple of possibilities:
1. You might not have communication between your pfSense box and the ISP gateway.
2. You might not have a default route, hence your pfSense box might not be able to determine where to send a packet to (say) 8.8.8.8 to get it forwarded to 8.8.8.8.

Please provide the output of pfSense shell command```
/etc/rc.banner ; ifconfig -a ; netstat -r -n

You can use _Diagnostics_ -> _Command Prompt_ in the pfSense web GUI to capture the output of a pfSense shell command.

I forgot the first thing to do to check the direct connection of ISP to my desktop.
my FA converter lights is up and that's why i forgot to check direct connection.

This should be the problem not with the PFSense.
Anyway thanks for the replies and it help me a lot.
