WAN webGUI access after fresh remote install

Marlepou

Thanks for your help.
What I tried so far:

easyrule pass wan any <MYPUBLICIP> any any
easyrule pass wan tcp <MYPUBLICIP> <FIREWALLPUBLICIP> 443

I saw each time the

Successfully added pass rule!

But still no access to the webGUI.

I checked with

sockstat | grep 443

that nginx is listening on port 443 and got

root nginx 24254 5 tcp4 *:443 *:*
root gninx 24254 6 tcp6 *:443 *:*
root nginx 24187 5 tcp4 *:443 *:*
root gninx 24187 6 tcp6 *:443 *:*
root nginx 24136 5 tcp4 *:443 *:*
root gninx 24136 6 tcp6 *:443 *:*

I don't understand the use of your rule, what is your 192.168.10.3 IP?

All I want is to access the webGUI once from wan to restore a previous config and my VPN access, then everything will be fine again.

When you check with

sockstat | grep 443

you will see that a root process called nginx listens on all known interfaces, using both tcp4 and tcp6.
What are these known interfaces ? ;)

I guess 127.0.0.1 - and ::1 - LAN, tcp4 and tcp6 and I hope WAN tcp4 and tcp6.
W'll presume WAN exists ^^.

The little known secret is : yes, the nginx web GUI server is listing on the WAN interface (I would loc it down to LAN only, but, who am I to decide ^^ - you wouldn't agree we me here).

Check your command line options.

I said :
easyrule pass WAN TCP any 192.168.10.3 any
You said
easyrule pass wan any MYPUBLICIP any any

My interface is called WAN not wan.
Protocol is TCP, as it is known - 'any' usage is ... dono : awkward ?
My next any == source which should be any ne (from the internet)
My 192.168.10.3 = the destination = my pfSense WAN IP.
The last any is [destination port] and is optional.

Type easyrule without parameters to see the help text.

Your command is wrong, as MYPUBLICIP will get interpreted as the source IP.

My WAN IP :

192.168.10.1 is my upstream ISP router - it has only one device on it's LAN : my pfSense, using 192.168.10.3.

@gertjan
There are only two interfaces:
WAN (wan) -> igb0 -> v4/DHCP4: x.x.x.x/24 where x.x.x.x is what I called <FIREWALLPUBLICIP> above,
LAN (lan) -> igb1 -> v4: 192.168.1.1/24

I am trying to access the webGUI from a remote location which public IP is y.y.y.y where y.y.y.y is what i called <MYPUBLICIP> above.

So my understanding is that my command should work as <MYPUBLICIP> is the source IP and <FIREWALLPUBLICIP> is my pfSense wan IP.

Following your answer I tried the command with wan and tcp in both lowercase and uppercase, but no change.

@marlepou does "pfctl -f /tmp/rules.debug" show anything notable?

There is this: https://docs.netgate.com/pfsense/en/latest/troubleshooting/locked-out.html#add-an-allow-all-wan-rule-from-the-shell. If you're going to immediately restore from backup it's not that dangerous to have the login page exposed for a few minutes.

That's the next item down from https://docs.netgate.com/pfsense/en/latest/troubleshooting/locked-out.html#add-a-rule-with-easyrule which looks like what you're trying already.

Thanks for your help.
I have tried this script already but nothing changes :(

And "pfctl -f /tmp/rules.debug" doesn't return anything at all.

@marlepou said in WAN webGUI access after fresh remote install:

doesn't return anything at all

That sounds like a worse issue since I would expect that shows the active default set of firewall rules.

You could https://docs.netgate.com/pfsense/en/latest/troubleshooting/locked-out.html#disable-the-firewall
Or get access to a device on the LAN and try to connect, if that is allowed.

or at the console:
4) Reset to factory defaults
(which is DHCP on WAN)

@steveits
Even with the pf disabled (pfctl -d) I still have no access.
And an nmap on the wan IP returns all ports (the first 1000) as filtered even though the pf is disabled...

Edit:
And I forgot to answer you: I have absolutely no access on the LAN side without the pfsense properly working.

Maybe I should try to reinstall from scratch with a 2.5.2 (which surely used to work) instead of the 2.6.0 just in case.

@marlepou

Use the dmesg command to see the kernel boot log.
Interface were found, and activated ?

Run ifconfig. Can you see the LAN and WAN drivers, the IP, are the interfaces "active" ?

Marlepou

Problem solved !

There was an active firewall ISP side filtering all incoming connections.
With it deactivated, I have been able to reach the pfSense and restore the config.

Everything back in order.
Thanks a lot Gertjan and SteveITS, your help was much appreciated!

I'd like to tag the thread as [SOLVED], but I can't edit my initial post any more.

What should I do?
