Topic: Monowall Blocks DHCP  (Read 1038 times)

I am a new Monowall user, and I am trying to set up Monowall as only a firewall on my home network.  According to the firewall logs Monowall is blocking DHCP requests, and I have been unable to resolve this issue.  I have an existing router/DHCP server and do not need Monowall to provide this functionality.  My network configuration is set up as follows:


                                                        OPT1                WAN
            Home Network <-----------------------> Monowall <-----------------> Router/DHCP server <------------>  Internet

                                                               Nokia IP130

I bridged the OPT1 and WAN interfaces on the Nokia, and I am using the generic PC 1.34 version of Monowall.  I read of a similar DHCP issue in a forum post, and the workaround was to enable the DCHP server in Monowall and to check the box for "Only respond to reserved clients listed below".  I tried this but with no success.  I tried various firewall rules and my current rules are attached.  Would anyone have any suggestions how I may resolve my DHCP issue?

It would have been helpful to see the actual full log entries for the blocked packets.

Also, identify which interfaces are WAN and OPT1

My firewall log is attached.  My DHCP server has an IP address of 192.168.1.254.

Excuse my ignorance but I do not understand your request to identify the OPT1 and WAN interfaces.  The WAN interface is connected to my router/DHCP server.  The OPT1 interface is connected to my home network, and I have bridged OPT1 with WAN.  The WAN interface is configured for DHCP - this part seems to work in that an IP address is acquired.  If this information is insufficient please let me know.
