Cannot reach another lan
-
Hello all,
I’m at a point of frustration with a problem and hoping someone can help.
I’ve got two subnets set up on two different interfaces:
• LAN 1: 192.168.10.1 • LAN 2: 192.168.20.1From LAN 1, I cannot reach anything on LAN 2 and vice versa. I try to reach the GUI webpage for a switch on LAN 2 from LAN 1, and the request says “address unreachable.” Pinging the default gateway from a device on the other LAN doesn’t work either; the command prompt just says “transmit failed. General failure.”
I have a firewall rule on each of the LANs to allow all traffic on any protocol between any source and destination.
The LAN 2 interface is enabled and handing out IPs.
I’ve checked that both LANs have routes for each subnet.
I’m using a network card that should be compatible (Intel I340-T4).
Packet capture shows that nothing is leaving or arriving on the LANs.
I’m very stuck. I’m okay at setting up networks, but this has left me befuddled.
Any help is greatly appreciated.
Thank you,

Can you confirm that when you activated pfSense the first time, when you had a WAN and a single LAN, everything worked ?
Then you activated OPT,1 and you called it "LAN2", and everything stopped working ?
I saw you've changed the default LAN IP network from 192.168.1.1/24 to 192.168.10.1/24
You've edited also the LAN DHCP server to reflect these changes ?@pfdense said in Cannot reach another lan:

Of course. Otherwise you would have a real problem.
But you didn't say the same thing for LAN.... why not ?@pfdense said in Cannot reach another lan:

I believe you. Can you show them ?

I simply had not connected it to a WAN. I guess that activates it? I connected to a working WAN, rebooted my modem and the router. After that I was able to get back and forth between the two LANs. Though I am still unable to get to the switch GUI on LAN 2 from LAN 1. But I can ping the switch. May start a new thread for that if I can’t figure it out. Thank you for your help. I did not know that of pfsense needed to be activated by getting it online first.

Me neither.
I can disconnect my WAN, and interconnection (routing) between LAN1, LAN2 etc keeps on working.LAN should work when you fire up pfSense as this is needed to, for example, configure WAN as a PPPOE connection. This can't be done with the console,you need the GUI to be accessible.

I was able to get to LAN 1 from a host. I was unable to go between LANs 1 & 2 until I had gotten pfsense online with my internet connection. Not sure but that resolved the issue for me.
I can now disconnect my WAN and still go between the LANs. But I was not able to do this until I had an internet connection through the WAN first.
