Yet another NAT issue :: nothing seems to work

skamal

Hi! I am trying to set up a nat in my 3 nic box, and apparently it is not working. Let me give you the picture

WAN :: DHCP from the ISP (real IP), but it seemed to catch the same IP every time
DMZ :: 10.x.x.x series IPs, and the hosts can go out to the internet
LAN :: 192.168.x.x series IPs, and they too can go out to the internet and also to the DMZ

Now, I have set up a web server in the DMZ, with an IP of 10.x.x.17, which can be reached from the LAN. I get the pages quite easily.

I wanted thiese to be available from the WAN side, so I have added one rule by adding a rule on the WAN port, through Firewall -> NAT > Port forward, where I have said that the port 80 from WAN should be mapped to 10.x.x.17 port 80. It has updated the firewall rules in the WAN bit and I have activated the changes.

Ideally, at this point, I am supposed to be able to browse to http://WAN-IP:80 (or without :80, doesn't really matter) – but the page is timing out!!! I can still browse the DMZ IP, 10.x.x.17 without any problem; but nothing is reached from the outside world.

I have checked the google, and also the tutorials, but either I'm too dumb to understand where the soluton lies or maybe it is a bit too cryptic to be notices.

Would appreciate if someone could please point out if I have done something wrong and how to go about it.

Thanks and regards

Hello,

You don't mention if you are trying to contact it from inside your NATed network. ?!
(Basicly going from 192.168.x.x through NAT to you external WAN-IP.)

Have you checked the setting "Disable NAT Reflection" in System / Advanced ?
Is it ticked or not ? (for reflection to work it should NOT be ticked in as far as I know)

Here is some information about "NAT Reflection" that you use when doing the above.

Also there may be a bug somewhere ?!

Thanks to cmb and mrzaz for the response.

Now that I have checked from an outside host, I seem to be able to browse the web server – which I couldn't from inside, which means redirection is working. Also, I didn't know that they could be handled in such a different way in PF -- apparently a lack of experience with that.

But that solves the trouble for the time being. Thanks for the links to pf doc, I'm reading it at the moment.

Thanks again.

Regards
