Accessing modem from inside firewall

balubeto

Does your PPPoE work if you get rid of all the modem access junk? Is there anything interesting in the PPP logs? Are you sure the modem is in bridge mode?

After you get PPPoE working again and you go back to trying to access the modem, are you sure it's 10.0.0.0/8 and not 10.0.0.0/24?

Why should I put 10.0.0.0/24?

Thanks

Because that's the netmask the cable modem is configured for? I asked if you were sure. I didn't say you should change it.

And on your Modem_access Interface you should UNcheck "Block private networks".

How exactly do you think your nat is going to work? You have 10.0.0/8 as dest but you also have it a source for your lan automatic nat, etc.

What I would do is START over!!! delete all that crap.. And why again do you think you need to run a bridge on pfsense?

And I find it highly unlikely your "modem" is using /8 as its mask for its 10 address.. Your status doesn't even show your wan interface up..

I noticed that if I enable the Interfaces –-> Modem_access interface and, then, I click on the Connect button on the Status ---> Interfaces, the firewall connects to the Internet but the computers on the LAN have no more Internet. Why?

Prob has something to do with running same 10/8 network on both your wan and lan? Or maybe some nonsense you did with a bridge??

What I would do is start over!! NO freaking bridges… Actually validate what your modem is using for its mask on this 10 address. And then create your interface using that.. And don't use an overlapping network on your lan side, etc.

Excuse me, but how do I solve my problem?

My gawd dude… I just told you!!

Lets start with basic info number 1... Ok your modem is using a 10.address - what is the mask on that? I find it like impossible to believe it would be /8 so what it /24?

So if its 10.0.0.1/24 then make your interface 10.0.0.2/24

On the lan side of your network - do not use ANY networks that are 10.0.0.0/24 or that would overlap it like 10.0.0.0/8 or /16 or /23 etc.. -- say away from all 10 networks would be my suggestion.

Then create your outbound so when you want to talk to 10.0.0/24 you nat to your 10.0.0.2 address. Using hybrid mode put that outbound nat above your automatic nats.

And don't create any freaking bridges!!! You have ZERO use for them!!

So, can you explain in detail what I have to do to try if your idea works?

Thanks

How is that not enough detail for you.. .Really?? Do you want me to remote to your system and do it for you?

What are the images that you need to be able to solve my problem?

I already solved your problem multiple times and told you exactly what do for gosh sake…

The info you need is in the access my modem article..
https://doc.pfsense.org/index.php/Accessing_modem_from_inside_firewall

Here are some pictures.. Now I have to use a vip to do this since I am actually using my WAN with a public IP on it.. But you are using pppoe so you would do this via interface actually assigned to your WAN interface.

So my modem uses 192.168.100.1/24 -- I know its a /24 because when it doesn't have a isp connection it hands out IPs via dhcp in 192.168.100.0/24 And doesn't really matter if you have the mask exactly right as long as your not overlapping with your other networks, and your modem and IP on your wan are in the same network.. So use /24!!! is your best option if you do not know for sure what the mask is..

So I create VIP.. You would do it on your wan interface that your calling modem_access.. You then create an outbound nat that says hey when going to that network from your source use this interface address..

You can see me accessing my modem, you can see the states in the state table on pfsense.. What is it that your not understanding here??? Do you not understand how pfsense nats to yoru public network?? Its the SAME freaking thing.. But only to another rfc1918 network..

Which devices are the 192.168.100.2 and 192.168.9.x IPs displayed in your image?

Thanks

That is my freaking VIP… Its right there in the freaking pictures!! What do you not get?? Nobody can be this freaking dense.. Your just freaking trolling now...

balubeto

router=10.0.0.1/24
Firewall=192.168.1.1

I still can not access the router. Why?

ptt

Because "you're doing it wrong" ! ;)

As pointed/noted before, since you are using PPPoE on WAN, the VIP is NOT needed/necessary….

Dude I think he is just trolling nobody can be this freaking dense… Its just not possible.. It's been stated over and over again.. I think his just thinks its funny to see how long we will continue to try and help him..

balubeto

The ptt's solution works in part because I can access the router but, when I disconnect and connect the PPPoE service through the Status –-> Interfaces window, the Internet does no more work:

While the johnpoz's solution (logically disabling the Modem_access interface) does not work because I can not access my router:

In addition, some of you wanted to know the interfaces and the bridges that I have:

So, how do I solve my problem?

Thanks

ARrrgghhh I am done with this thread - you clearly are freaking trolling.. Who told you to turn off your PPPoe? Connection.. And why and the F are you bridging all your interfaces… Told you not to do that!!! WTF dude???

Nobody can be this freaking DENSE.. .Clearly your just trolling hope you having fun... Im out..

Even if you wanted to bridge some interfaces... Nobody can be this freaking stupid... Really!!!

How would this freaking work dude?? Come on!!! If you just don't have clue one on what a mask is or what IPs are then say so.. Once again you have 10/8 as a dest and on your lan side?? And you put a 192.168.1. on your modem_access (wan)?? What???

In your image, how come your pfSense has created the two automatic rules where the 10.0.0.0/8 address also appears in the Source? To me this address does not appear.

Why?

Thanks
