Firewall/NAT

Good evening,

Let me explain the situation. I use two PCs that have VMware installed on it. The first contains two VMware servers and a client Monowall, the second 2 servers and clients. The first machines were the ranks of 192.168.1.X IP (LAN Monowall) and the second 192.168.2.x (WAN Monowall). I can ping each of the two ranges.

Machines that are the ranks 192.168.2.x can not use DNS (IP 192.168.1.2) but can ping yet.

I think M0n0wall blocks requests for DNS, but I do not know where.

Could someone explain to me how solve this problem?

PS: I have a rule at the firewall level that lets all protocols from all sources from the WAN.

Thank you in advance.

Am I correct in assuming that you don't have an actual WAN connection and that you are just using the m0n0wall to route/firewall between your two internal networks? If that is the case - I'd recommend moving the network you have plugged into the WAN in to an OPT interface. That way, both internal subnets are on the same "side" of the firewall and things are much easier to configure.
