Vanilla install PFSense Business Test – no internet

cmb

Go to interfaces > wan
Look for "block private IP"
un-check it.

Don't. No relation.

Check what Steve said.

Not necessarily true genius unless you can KNOW for sure that he didn't accidentally pass a private IP to the WAN.

People are forever thinking they bridged a modem/router but didn't get it right accidentally. I'd say 9/10s of the time that the case in a situation like this where a vanilla install of pfsense doesn't work and some other cheapo router does. Its just a thing to check.

If the bridge was done incorrectly or not at all, which is often the case, allowing a private IP on the WAN would show that quickly.

Then, if that is the problem, he could fix it.

So, CMB, its at best, POSSIBLE that what I suggested will make no diff. Depends on if the OP got the bridge right.
Its one freakin button click. If it changes nothing, its one button click to change it back.

Another possibility is that the ISP is disallowing his MAC, in which case cloning the MAC of the working router, presumably the one that was there before pfsense, should clear things up.

I've seen both cases many times.

I'm not arguing that you shouldn't disable 'block private networks', indeed if the WAN is in a private subnet you should for the reasons I gave. In fact I'm not trying to argue at all. ;)
It's just purely for information because I see this suggested a lot by many people as a cause of 'no internet on LAN'. When diagnosing this type of issue you need to be aware that the 'block private networks' rule cannot prevent clients on LAN from accessing the internet.

Now getting a private IP on WAN when you thought the modem was bridged in some way, that's a definitely a clue that something is amiss. :)

Its not so much you steve. Your advice is in fact reasonable and valid.

But CMB was out of line, and possibly wrong (its a coin toss - depends on the proficiency of the OP)

There is just no good reason to show up saying don't try something unless you are 100% sure it will have zero effect.

When I posted the original suggestion it was with full knowledge that it might not help anything.

In which case I'd suggest checking the MAC.

In fact there is a laundry list of simple checks that need be done if that fails.

Could be any simple thing - but its definitely something simple.

BTW - I presumed things on the LAN are working fine.
OP states "cannot resolve to anything external".
With that language, could be DNS I guess. I'm doubting it though if he really is using a default install.

chpalmer

I presumed (a) default PFSense default of the box was ready to roll.

Usually is. :)

OP= Try imputing one of these IP's and see if it makes it… they should all take you to Google.

173.194.33.174
173.194.33.160

173.194.33.164

If it works- how is your WAN setup? DHCP, Static,… ??

@kejianshi:

Wrong. That affects only traffic sourced on WAN.

@kejianshi:

I only state things in such a fashion where I am 100% sure it cannot affect that scenario. It can't.

Yep-

I have a client that has a 10.x.x.x ip on their WAN as they are on a wireless internet provider and actually in this case on a local router across the highway on their own wireless bridge (over a VLAN) plugged directly into fiber. 2.5ms to a major fiber backbone, very cool!

The only reason I had to uncheck the "Block Private Networks" box was to allow the ISP (whom I work with and trust) to be able to log into the pfSense box from the WAN side. We were online just fine before that.

kejianshi

I've had to uncheck that box for every double NATed pfsense I ever connected. (Private IP on the WAN)

Must be just me (-;

cmb

The only scenario where you have to disable that is if you need to pass in traffic on WAN initiated from a private network. That's almost never the case in double NAT scenarios along these lines. Most only time that's necessary to disable is where the system is an internal router/firewall, or other circumstance where its WAN is connected to one of your LANs.

kejianshi

So just to test again I went into my pfsense VM that is running locally and checked "block private IP" on the WAN because it does have a private IP.

And nothing happened… I expected it to fail.

Which was quite weird for me because in the past on my Verizon FIOS and on comcast I've always had to un-click that button.

So I was wrong.

So still has me wondering whats up with this guy's machine?

DNS? MAC for wan interface? Other?

Thanks for all suggestions - Results as below
Ive also attached some screen shots which I hope may help

ACTIONS based on suggestions in this thread:
Go to interfaces > wan ->Look for "block private IP"- >un-check it.->Save.=no change
On the dashboard is it reporting 'you are on the latest version' or 'unable to check for updates?= “Unable to check for updates”
When you try to connect to an external host from the lan what is the error given?= through browser no internet access
Ping google.com_= Ping request could not find google.com. Please check the name and try again._
Ping by IP __= Request timed out.
Pinging LAN devices = no issues all devices respond
STRANGE THING- when I cloned the MAC address and ping I got a outside result (see capture.png)
I thought i had cracked it! then next ping nothing. I dont understand that at all?? Pinging anything after this result failed (by name or IP) nothing.
VERY strange & frustrating.
Truely any advice would be grateful

Can you put the screenshot of Outbound NAT rules.

B00M3R

Outbound NAT

outboundNAT.PNG_thumb

Wolf666

There is no rule…..so no lan traffic will be outbound NATd.

Try to add one manually as follow:

(unchecked)

Interface = [ WAN▼]
Protocol = [ Any ▼]
Source = Type: [ Network ▼]
Address: [ YOUR_LAN_IP_SUBNET ] / [ 24 ▼] (should be 192.168.1.0 from your screenshots)
Source port: [_____] (empty/blank)
Destination: Type = [ Any ▼]
Translation: Address = [ Interface Address ]
Description = [ LAN -> WAN ]

kejianshi

Maybe you had two simple things wrong…

Cloned MAC and Something Else...

kejianshi

When outbound NAT is set to automatic, no rules are listed. That should be fine.

However, I noticed that DNS is not a default configuration. So its not vanilla.

What else did you change?

Wolf666

@kejianshi:

When outbound NAT is set to automatic, no rules are listed. That should be fine.

My ignorance since I only use manual outbound.

kejianshi

Me too - I stopped using automatic a while ago.

But I think for 1 wan, one lan, just testing basic features automatic might be best.

@Wolf666:

My ignorance since I only use manual outbound.

Confusingly if you switch to manual and then back to automatic the the rules remain. ;) But, yes, showing no rules when set to automatic is the expected behaviour. I would always recommend using automatic unless you really need to use manual. In 2.2 there is a hybrid mode which is much better.

You have an IPv6 gateway on WAN and it's not working, probably because your ISP doesn't support IPv6. If that is set as default then this could be at least part of your problem. It would explain why the pfSense box cannot check for updates.
What does your System: Routing: Gateways: screen show? Which is default?

You can probably just set the IPv4 gateway as default there and it will work. However unless you're using IPv6 you should go to the WAN setup and set the IPv6 config type to 'none', then remove the gateway from the System: Routing:

OK kejianshi to clean up i chose Option 4 "Reset to factory defaults" went through the start up process chose no VLANs added nfe0 as WAN & nfe1 as LAN then through start up wizard through GUI or left as default. Everything sweet? LAN machines picked up DHCP address WAN has IP. Also removed IPv6 as suggested. still NOTHING!!
so frustrating…
The modem i have is a netgear DG632 set up in "bridge" mode or RFC1483 modem does nothing but pass traffic. Plugged into my ASA as previously mentioned doing the same, it works fine no issues.

If you are suggesting vanilla config works out of the box this doesnt seem to be the case for me. new setup pics attached
