[Solved] I'm apparently unable to port forward...

@johnpoz Yes, I was thinking about spoofing the WAN mac..

About the public address block, I also don't know how they work.. sometimes I get 186.X, sometimes 187.X, and sometimes even 201.X.. it's really weird..

~~I'll check right now if I have ICMP rule enabled here...~~ yes, I do....

~~And will also try to ping your IP (though I already did that with no success the other day)~~ Yeah, no response..

Weird thing is that I can ping your IP using this tool.

@johnpoz :

Is this your ISP?
ALGAR TELECOM S/A

Ah, sorry.. no, it's not. My ISP (ViaReal) probably use AlgarTelecom's route.

I ran a Traceroute to your IP and it stopped at eqix-dc2.wideopenwest.com [206.126.236.136]. Can you try one at my direction and send me the screenshot?

Thanks.

So your ISP is forwarding outbound connections from you but dropping inbound connections. You'll have to ask them why that is.

Look at this NONSENSE tracing to you..

>tracert -d 201.162.x.x

Tracing route to 201.162.x.x over a maximum of 30 hops

Not quite sure how you got those responses at all there.

johnpoz

Yeah I don't either clearly something WAY wrong there.. Should be impossible to get such an answer.

Derelict

I suppose it's possible that nobody along the path is filtering for that.

@Derelict :

So your ISP is forwarding outbound connections from you but dropping inbound connections.

That's not totally true.. my friend from a city far away can ping me with no problems. And also, I can't ping John's address either, so I guess the problem is up higher... I can get past Algar which I guess is my ISP's route, and John can get up to Algar in the opposite way..

I really don't freaking know what's happening, but I've seen it before.. A few months ago I tried to, but I couldn't access a website my friend from the US was hosting at his place, and he narrowed it down to be a Comcast router blocking incoming traffic from me (I'm in Brazil).

So, what I meant with all this is that it may not be my ISP, and also may not be yours.
(btw, all this time I've been using my Mikrotik router, not the pfSense. Though I'm waiting for my dad to go have dinner to swap everything).

Derelict

Which is why I use the term "upstream."

Nothing else out on the internet knows squat about what device you are using. That is between you and the first hop.

If a router somewhere out there is blocking your IP address, it would not matter if it was pfSense or the mikrotik connected at your end.

@johnpoz :

(...) clearly something WAY wrong there..

Indeed. I have no doubt that my ISP isn't capable of doing things right..

NinoM4ster

@derelict I'm fully aware of that. I was just mentioning.

johnpoz

So if your IP your current router works for routing... Then have pfsense use the same mac so it gets the same IP and you should be fine.

Also it would be your ISP job to troubleshoot why your IP can not get to another IP, or why some IPs can not get to your IPs... They are the ones that advertise their routes, etc. If there is something wrong upstream for their networks then they are the ones that need to work out the problem... Not the end user.

Derelict

My recommendation is to solve the issue with the other gear/MAC and the ISP before resorting to things like MAC spoofing. To me that stuff should be a last resort. Certainly doesn't cost anything to try it but if it does fix the problem I would pursue getting it working with the native MAC address.

(If that is actually the problem which is becoming less and less clear with every post)

johnpoz

Not so much what the mac is - but he gets an IP in a completely different netblock.. 2 different /24 not even in the same parent..

Derelict

Right. That should be sorted out with the ISP using the new MAC address. Then there isn't some MAC spoofing hack in the network.

johnpoz

Agree any IP he gets from his ISP should work... But would be a simple test to see if it works when he uses the same IP.. Which is info he can take to the ISP.. This IP works - this IP doesn't.. Which he could do now - but I still think he thinks it has something to do with pfsense. Getting pfsense to work when it has the same IP would prove to him its upstream from him and not pfsense.

Derelict

right.

Certainly doesn't cost anything to try it but if it does fix the problem I would pursue getting it working with the native MAC address.

I just don't like long-term bandages on my networks. You never know when, for instance, your particular mix of "extra" things that nobody else has will fail on an upgrade, etc.

MAC addresses change. ISPs need to deal with it.

NinoM4ster

Ok, just an update. I got the pfSense box running with the spoofed mac, and indeed, I got a public IP on the same block.. (though not exactly the same address.. the last part changed).

alt text

I'm gonna take my time now to do everything I can to get this thing working already..

NinoM4ster

Another update.. I finally learned how to use Packet Capture, and I do receive stuff on port 8889 when I hit a scan on canyouseeme.org .

So far so good. Gonna try the damn port forwarding now.
