Multi LAN single WAN

[Albertus]

I have the following:

1. WAN - 172.16.20.10/24
2. LAN1 - 192.168.3.0/24 (192.168.3.254/24)
3. LAN2 - 192.168.4.0/24 (192.168.4.254/24)

WAN working great from both LAN's but i would like "connect" both LAN's as i would like to ping for instance:

192.168.3.100 to 192.168.4.100 and
192.168.4.100 to 192.168.3.100

i used google to find solution but with no luck yet.

Anyone who can guide me in correct direction?

Thank you

This should really work out of the box - what are you rules on lan1 and lan2?  Your problem is most likely firewall on 4.100 blocking pings from 3.100, and vice versa

[Albertus]

Thank you for reply my rules are:

LAN1:

Anti-Lockout Rule

IPv4 * 192.168.3.0/24 * * * * none   ANY

LAN2:

IPv4 * 192.168.4.0/24 * * * * none   ANY

3.100 and 4.100 are both windows 8 laptops, but no luck pinging each other.

If you have some kind of antivirus or firewall running on host computers, they would normally block other subnets.

[Albertus]

So no routing to be set only firewall settings then 2 pc's on different ip ranges should ping each other?

[Albertus]

I tested firewall disabling and it works.

Just another question:

if i want pc's to see both ip ranges without disabling firewalls how would i do it?

[Derelict]

The PCs can see both ranges but the PC firewall is blocking inbound traffic from other than the local network.  You would have to tell the PC firewall that 192.168.2.0/24 and 192.168.3.0/24 are both to be considered local, trusted networks.  How to do that is outside the scope of pfSense.
