Enable internet access from LAN

According to him the 104.x.x.x/24 is his pfsense wan.. And yeah its his school network..

stephenw10 · Apr 6, 2020, 12:42 PM

Ah, yes. Ok then test from that subnet to the IP directly, with those rules it should connect.

maale · Apr 6, 2020, 4:36 PM

Thanks

Still doesnot work, I tested it from an external builted vm machine with IP 104.x.x.15 with gate way =104.x.x.254, although I can ping the external mail server address:104.x.x.35 but cannot connect to it!!!

could you please let me know what can be the problem?

johnpoz · Apr 6, 2020, 4:44 PM

There is all kinds of things that could be the the problem.. That just means your pinging something 104.x.x.35... Why would you think that would be your mail server if its behind pfsense, is that pfsense wan IP.

Which I doubt - since from you rules on your wan your not allowing to ping its wan ip.. Or any icmp even, so highly much doubt that is even psfense.. And sure isn't something behind it, etc. etc..

If you want help - I suggest you get with your teacher.. I'm not here to teach a class in basic networking, so you can get an A..

To troubleshoot port forwarding.
https://docs.netgate.com/pfsense/en/latest/nat/port-forward-troubleshooting.html

But again, from what you posted I highly doubt that .35 is even pfsense wan IP... Since you do not allow that on your wan interface - so you wouldn't get an answer if you pinged it..

I agree. If you're genuinely testing from the WAN subnet and the pfSense WAN IP is 104.190.x.35 then your firewall rules should be blocking that ping.

So either you're pinging something else or you changed the rules since you last screenshot.

@stephenw10
yes I have only changed the WAN rules to alow ICMP.
.
thanks

stephenw10 · Apr 6, 2020, 5:37 PM

Ok, what ports do you have in the web alias?

maale · Apr 6, 2020, 5:42 PM

@stephenw10

stephenw10 · Apr 6, 2020, 5:50 PM

Ok it looks like your port forward for that server is listing at 104.x.x.5 but you are trying to open 104.x.x.35.
Is that just a typo? Correct it if so.

If it's a VIP on the WAN then try to open that IP.

@stephenw10
I have 2 servers, one is web sever has external IP 104.190.X.X.5 and internal 192.168.1.5, second is mail server has external IP 104.X.X.35 with internal IP 192.168.1.5, I want both be behind pfsense and accessible from outside through port forwarding

yes I have virtual IPs
sorry, what do you mean by opening that IP?
do you mean set a LAN rule with destionation address =104.x.x.5 ?

maale · Apr 6, 2020, 6:17 PM

@maale
Sorry, I mean a WAN rule

stephenw10 · Apr 7, 2020, 5:31 PM

I mean try to open the page by IP address directly rather than URL which would need to resolve.

Both those IPs look like they should work though assuming the server can respond.

Check the pfSense state table in Diag > States while you;re testing. You should see the states on WAN and LAN complete with NAT on WAN.

Steve

johnpoz · Apr 7, 2020, 5:35 PM

So what is your actual IP of your pfsense wan? You have vips of .5 and .35 - what is the actual IP?

Have you gone through the troubleshooting doc I Linked too - finding the issue with port forwarding is 2 minutes work tops!!! do a sniff do you see the traffic on your wan or not? Sniff on lan - do you see it send the traffic on?

For all you know the traffic is being forwarded and your system your forwarding to firewall is blocking the traffic - very common!!!

maale · Apr 8, 2020, 6:57 PM

@johnpoz
Thanks!

The problem was that the routing environment doesnot support Virtual IPs.
All traffic should be hit the pfsense WAN IP at 104.x.x.10 .So, I have set an external DNS with an IP 104.x.x.25 with my domain and records www.x.av for web server and mail.x.av for mail server, with port forward rules.

Now from an external machine 104.x.x.15 using the domain www.x.av I can access the web server, but using the domain mail.x.av, this directs me to the same webpage for the web server but not for the mail server. Is NAT reflection what I need to do?

johnpoz · Apr 8, 2020, 7:00 PM

@maale said in Enable internet access from LAN:

routing environment doesnot support Virtual IPs.

Huh - that makes no sense at all.

Is NAT reflection what I need to do?

No its not... if you want host.domain.tld to get sent to X, and other.domain.tld to get send to Y behind pfsense then you need to use multiple wan IP, vips or not... Or you need to hit different ports in your url, or you need to setup a reverse proxy to know that host.domain.tld goes to X and that other.domain.tld goes to Y.. Look at the HA proxy package.

maale · Apr 8, 2020, 8:01 PM

@johnpoz
I mean the lab routing environment.
ok I look for the HA package

johnpoz · Apr 8, 2020, 8:09 PM

Lab routing environment or real routing environment... Has zero to do with anything - an IP address that is in same network, has zero to do with routing...

stephenw10 · Apr 8, 2020, 8:59 PM

Mmm, that.

Why can you not use multiple IPs on WAN? What VIP type were you trying to use? Use IPAlias if you were not.

Steve

johnpoz · Apr 8, 2020, 9:10 PM

Maybe he meant their virtual environment that pfsense is running on? Maybe issues with vips in some VM setups, where you might have to do some promiscuous setting. But if VM, he could just create some new virtual interfaces and since he is using dhcp in this network.. He could have 3 different wan interfaces using 3 different IPs and then port forward..

maale · Apr 8, 2020, 10:27 PM

@johnpoz
I am trying to install the HA proxy package, but I cannot see any packages listed. could you please let me know why? I can connect to www.pfsense.org successfully. And I have installed bind package before, but now a I cannot find available packages
