Multiple LAN's

MikeyB · Jul 29, 2008, 8:51 AM

Hey guys,

I need a little help getting my second LAN to work, im new to this :)
I have been looking around the forums for hours now and can't find anything.

this is my set up.

DSL –> pfSense --> LAN 192.168.1.X --> Switch --> Servers, Desktops.
|
|------> WLAN
|
|------> LAN2 192.168.2.X

But anything on LAN2 cant access pfSense or the internet.

I have a manual outbound NAT rule set up, and firewall rule on LAN2 for any > any.

Thanks in advanced

Did you create a AoN rule that NAT's your second subnet?

Could you show screenshots of your rules?

Yeah i did, i believe its correct, i saw it in someone elses thread about this topic.

Also if i plug a computer in to the second LAN interface (LAN2) i get a DHCP IP but i cant ping the default gateway (192.168.2.1) nor the pfSense box…

The rules look good.

If you connect a client, can you ping it from the pfSense diagnostic-menu-ping?

No i cant, i can ping the interface (192.168.2.1) but not the computer connected to the interface

this is what i have from ipconfig… i dont know why i have a default gateway of 0.0.0.0 and 192.168.2.1

Have you tried another computer?

MikeyB · Jul 31, 2008, 2:52 PM

I will now.

I tried a desktop i have, it got an IP fine, got a default gateway fine… but it couldnt ping the gateway or pfSense.

Do you have an idea of whats wrong?

There is no reason to use AON in this configuration, NAT rules are automatically generated for all your internal networks, the auto generated rules are identical to what you have configured. That shouldn't cause any problems though, the NAT setup looks to be identical to what would be automatically configured.

Rules appear to be setup fine too.

What is assigning the IPs on this network? You sure this OPT interface is functional and plugged in correctly?

pfSense does DHCP.

If it wasnt working i wouldnt get an IP from it would i?

thanks for all your help guys, im stumped on this one

To me the gateway (0.0.0.0) seems strange, I would suggest to check the DHCP settings on lan2 again.

Further whenever I was working with mutiple LANs and tested it I with 1 computer I always en up with connectivity problems because of the ARP table. Make sure to flush it or to reset the pfsense box when ever you move your computer between the LANs.

MikeyB · Aug 2, 2008, 5:37 AM

I have reset it and tired but it didnt work.

DHCP settings on LAN2 are correct i beleive

cmb · Aug 2, 2008, 6:02 AM

Yeah if you're getting DHCP leases from it, it's obviously online… no clue what you might be seeing.

Delex · Aug 2, 2008, 7:15 AM

Does it work if you disable DHCP on LAN2 and use a fixed IP address and gateway on your PC?

^ Just tried that now, didn't help >:(

MikeyB · Aug 7, 2008, 5:41 AM

Try booting from a livecd and assign the nic's in console then follow my screen dumps.

Do you have a IPSEC VPN Tunnel terminating to the 2nd LAN??

For some reason, i can not ping anything on my 2nd lan from pfSense when a IPSEC Tunnel is running.. If i turn it off, i can ping all day long..
