Get public ip for pcs
-
@stephenw10 I've already managed to implement. xD I was blocked several times. Hahahaha
-
-
@stephenw10 I'm here with a big problem kkk. The ip addresses do not keep the ports open :( and in the firewall logs nothing appears to block the connection.
I have an open port 80 on a machine this machine has an apache. I've already tried to get a local ip and do nat routing and it works but with the public ip and with the firewall rules open I can't access it.
-
In a virtual machine with public ip it works because the two machines are connected on the same bridge. But if you try to access it from the outside, i can't.
It should probably be something on the pfsense firewall but in the firewall logs nothing is blocked on port 80.
-
How are those servers getting their IP? Statically configured?
If so the ISP is going to be ARPing for those IPs on the WAN and you should see that in a packet capture.
Can the servers connect out?
Steve
-
The servers get the ips through DHCP from my ISP I created a bridge from wan to lan.
pfsense has a public ip public through DHCP and this already works outside the network.The ips that are on the pfsense bridge does not work outside the network, only inside.
-
Ok, if the servers are pulling a DHCP lease correctly then the bridge is working.
Can the servers connect out to public IPs?
Your pass rules are TCP/UDP only so ping will not work.Steve
-
yes the bridge works.
I already added the icmp and the ping works to connect to public servers.
the only problem is that the ports are not open to the outside of these ips on the servers.
but on the firewall they are open and in the logs nothing to block appears. -
Run a packet capture on the WAN for one of the server IPs. Try to connect to it. What do you see?
-
no port

Mmm, well it sure looks like two way traffic there.
That's on the pfSense WAN interface?
.208 IP is the server there? What subnet mask does it have?
I assume the .173 IP is not in the same subnet?Steve
-
The ips that are assigned are from different subnets depending on the availability of the isp.
the mask is /24
Yes that was in the wan interface. But I send it again to be sure.
Yes the 208 was that which was assigned to the server.13:47:46.315025 IP 79.124.62.98.8080 > 176.79.22.208.9182: tcp 0

Really? What are the odds of that? But looks arp is working..
-
Do you know why the doors are not open to the outside? I already have my head in water :(
-
Mmm, you can see it's replying and that traffic is leaving the pfSense WAN.
Assuming you opened it to everywhere, as your rules showed above, I am not seeing any reply packets if I test from here.
So either something is blocking the replies upstream or the replies are going to wrong place.Increase the view detail in the pcap and make sure the MAC addresses are correct on those packets.

I had turned off the server
then everything was open.
I asked a colleague of mine to ping the ip 176.79.22.208 and he can't. on ip 176.79.20.129 which is the ip wan of pfsense it gets. it's a bit weird
-
@s_serra So if I traceroute to that IP.. Looks like it dies at what should be your gateway.

You really need to sniff on your wan when someone is say trying to ping you - if you don't see the traffic hit pfsense.. Well then no its not going to work. no matter what you do on pfsense.
-
I'm still a noob.
How can I sniff out wan's traffic?
my pfsense gateway is 176.79.20.1. Do I have to add more gateways to pfsense for the other subnets to communicate?

@s_serra said in Get public ip for pcs:
my pfsense gateway is 176.79.20.1
Not for that IP range it isn't - your device since its getting its IP from dhcp, should get an gateway in its network. I take its that serra box.. look at a netstat -r to see what its default route is (ie its gateway)
example here is linux box on one of my vlans..
pi@ntp:~ $ netstat -rn Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 0.0.0.0 192.168.3.253 0.0.0.0 UG 0 0 0 eth0 192.168.3.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 pi@ntp:~ $As to how to sniff. Under diagnostic menu on pfsense, packet capture.
You prob want to do that sniff in promiscuous mode - since the traffic towards 22.208 box is not pfsense network..
