Unable to connect between lan1 and lan2
-
@sutha Realistically there’s only a handful of things it can be:
- Incorrect subnet mask on pfSense or PC
- Incorrect gateway on either PC
- firewall on either PC
- firewall rule on pfSense
If it was a VLAN, VLAN/switch config.
-
It's almost certainly not a gateway problem since hosts on both LANs can reach the internet.
It could be a subnet mask problem if hosts are configured statically. If they use DHCP it probably isn't since you cannot configure conflicting subnets in pfSense.
If any hosts still have two NICs or additional IPs in both subnet they will be unable to connect to the other subnet.
Try to ping 192.168.60.1 (the pfSense interface address) from a host in the 192.168.50.X subnet. If that works then routing and firewall rules are fine and it's almost certainly the hosts themselves blocking the traffic.

@stephenw10 I was talking in general and wasn’t clear. Low on coffee. :)

@sutha said in Unable to connect between lan1 and lan2:
. Anyone got any idea what is blocking here
Now do the sniff.. When you ping a 60.x IP from a 50.x device.. Do you see the traffic get to pfsense?
And like to see the output of ipconfig /all from a device.. This will validate your mask is no messed up. And for good measure output of route print..

@stephenw10 I'm able to ping from lan1 IP:192.168.50.100 to lan2 ip: 192.168.60.1 and from lan2 ip: 192.168.60.50 to lan1 ip:192.168.50.1.
Works fine, but I'm unable to ping any other local pc. Example:
from 192.168.50.100 to 192.168.60.50, not working.
from 192.168.60.50 to 192.168.50.100, not working as well. -
@sutha And you could have 14 other interfaces.. On this machine and 3 different vpn interfaces.. How about a simple ipconfig /all output and a route print..

@sutha said in Unable to connect between lan1 and lan2:
Works fine, but I'm unable to ping any other local pc. Example:
If you can ping pfsense 192.168.60.1 from your 50.x device but not some other 60.x this SCREAMS!!!! firewall on the 60.x device..
Again simple packet captures that take all of 30 seconds will finally prove to you its your device and not pfsense..
-
Yup that^. Almost certainly a local firewall on the device you're trying to ping blocking it.
-
@johnpoz This is my ipconfig/all setting:
-
@stephenw10 This is my windows firewall setting, I don't have any other firewall setting between pfsense and my sysstem.
-
@johnpoz All I can see in the packet capture, when Isent a ping to 192.168.50.1 or 192.168.60.1.
I get a reply from the destination, but when I ping a local pc: 192.168.50.100 or 192.168.60.50.
I get no reply from other side. -
Need to see the complete output from 'ipconfig /all', all interfaces.

@sutha said in Unable to connect between lan1 and lan2:
but when I ping a local pc: 192.168.50.100 or 192.168.60.50.
I get no reply from other side.But you do the see the ping request in the pcap?
-
@sutha said in Unable to connect between lan1 and lan2:
I get no reply from other side.
But you see the request go out to 60.50 from from pfsense 60 interface? Or do you not even see the request come in from the 50.x device to pfsense 50 interface like you were seeing before when you had the tunnel?
If you see pfsense send on the ping request to 60.50 and you get no answer that is not pfsense problem.. If you do not even see the ping request come into the 50 interface of pfsense interface - again not pfsense issue. Pfsense can not route traffic it never sees.
Where we would need to look at pfsense for something is if you see the ping request come in on its 50 interface, but you don't see it sending anything out the 60 interface..
why is this showing your connected to 2 networks.. But your ipconfig /all that I ask for you only show 1 network
The output of route print would be most helpful here.
edit: I turned on my wifi to check if it might show that even if disconnected like your snipped output shows. It doesn't so from what you posted I would assume you have some other connection on this box.. That you didn't include in the ipconfig /all output, and we would of seen as well in the route print which you didn't post?
btw public would block ping that is for sure.. Put your interface in private, even if your going to turn off the firewall.. windows firewall has been known to be flacky... But the output of your pcap would tell us right away where the problem is - pfsense is either not seeing it at all, or pfsense is sending it on and the box being sent to is not answering.

@johnpoz Currently, I'm unable to provide you with the complete ping test results. While I was conducting the test, the LAN2 PC suddenly went offline. I won't be able to fix it until tomorrow. Here are the results from LAN1 and partial test results from LAN2.

Run the same ping test but capture on LAN2 and make sure you see the same traffic there so you know the pings are leaving LAN2 as expected.
If that is the case the problem is almost certainly that the host at 192.168.60.50 is blocking that ping because it's coming from outside it's subnet. What is that host?

@johnpoz 60.50 went offline. This system is on lan2 and I can’t access now. I’ll try tomorrow.
