[SOLVED]Getting kicked out from playing Overwatch

[Bob.Dig]

@NogBadTheBad There is nothing of interest, some open ports (NAT) and the country blocks which again is intended.

[Bob.Dig]

Umm just noticed in the first screenshot it says default deny rule.

I don't think this is a pfBlocker issue.

Asymetric routing perhaps.

I want to come back to that asymetric routing.
My ISP is doing something, so that my Router can't see its internet IP-Address, but a different address. Maybe that is the problem for the firewall?

[NogBadTheBad]

@Bob-Dig

So what are you using the pfBlocker GeoIP rules for on the WAN interface.

To Block all countries bar one for your inbound rules ?

[Bob.Dig]

@NogBadTheBad please see my posting above
And it is default on the wan interface and I am blocking almost everyone but some countries for incoming connections to my server, but is this really related to my Overwatch problem?

Your using pfBlocker wrong then.

You need to create an alias in pfBlocker and use it in a firewall rule to pass, doing it the way you are every packet will be evaluated top to bottom till there is a match.

[NogBadTheBad]

I think you need to talk with your ISP.

[Bob.Dig]

@NogBadTheBad One County or one list only would be easy because I could just Invert Source and everything would be fine. Your screen looks much more complicate to me.
So what I will do now is disable all geoblocking and all of pfblocker and will look if the problem still occurs.
Thank you for now!

[Bob.Dig]

I think you need to talk with your ISP.

It is a big one, Germanys second or third biggest cable-provider, so no chance, they do what they do.

Is it Telecolumbus ?

Whoever it is they are doing something funky as your router has a different IP address to what's reported by whatsmyip.

[Bob.Dig]

@NogBadTheBad Yes. But this IP is "made" for this and I can open ports etc. There is nothing I can do about it and maybe it is an pfsense-only or Fancy-Firewall-only problem.

[Bob.Dig]

@NogBadTheBad So after disabling pfBlocker I had no problem playing Overwatch, although it might be to early to say that definitely.

Anyway, maybe all this geoblocking was to much and had unintended consequences?

So I am looking at this alias permit thingy and I don't understand it at all.
When I permit something, where is it blocked in the first place to make any sense?
I made one up but couldn't see it under rules, where is it?
Maybe you have a link which fully explains it?

[Bob.Dig]

After watching it more closely I think I get it, how it works. Or at least, I am getting there.
Interesting...
But it doesn't work with NAT or does it?
It does, was on the wrong tab.

Now I have to see if it is any good:

[chpalmer]

Your on carrier grade NAT.

[NogBadTheBad]

@Bob-Dig

You just need to follow the screenshots that i posted to create an alias with all the countries you want to allow through then use it in your allow alias.

The less rules / matches the firewall needs to process the better.

[NogBadTheBad]

@chpalmer

Are those carrier grade nat ip address, never come across cgn before?

Also doesn’t cgn break customers doing port forwards?

That's what I did on my last screenshot. It is a little more complicated to set up or maybe there are more easy options I don't know. Also I hope this will help with Overwatch, I still don't know for sure, because I like this game but only in small doses.

Whatever they do, I can open ports, so would be interested to know the right term for that.

PS:Still getting marked as spammer here, even without VPN, I have to remove the beginning of each quote.

@NogBadTheBad I also made some port aliases so my rules on WAN now look more clean (less rules). Again, thank you!

Yep. Many people will be behind the public IP address he is behind. no way to port forward and that address is not routable from the outside. Any kind of port forward would have to be set up by the ISP you your NATt'd address.

Technically you are double NATt'd.

Id be interested to see your firewall logs..

pfblocker would be pretty useless on the WAN.

[Bob.Dig]

pfblocker would be pretty useless on the WAN.

Don't ask me how it works but I can instantly do port forwards by my own.

[chpalmer]

So you have open ports from the outside?

If for some reason your ISP was NATting every address in their system I suppose they might put you in a DMZ of sorts.. Can you do a test at GRC.com and show the results here?

https://www.grc.com/x/ne.dll?bh0bkyd2

Ive already tried a port scan and came up with nothing. You might have the US blocked so Id understand but..

Just because you can build a port forward doesn't mean anyone is getting to you. Maybe other customers behind your CGNAT..

[Bob.Dig]

@chpalmer Like I said before, yes I can. You can believe me or not...

And I had no more problems with overwatch after changing the geoblocking to what @NogBadTheBad has suggested.
