Topic: how to setup a m0n0wall behind another  (Read 3828 times)

Hi there,

I have to build up two m0n0walls in a row. The reason herefor is, that there are two companies using one DSL-connection (which for now is not possible to be changed). Unfortunately I only can acces the m0n0wall that I try to setup. The other one has three Ethernet cards (WAN, LAN (other company), OPT1 (my company)). The OPT1 interface is now connected to my switch. I would like to put my own wall in between and already tried to configure my WAN-interface as "DHCP" and "Static". I also tried to put a statich route and many other options... without success.

Does someone have any idea, how I could run my m0n0wall in this configuration?

Thx for your help,

whity

there's nothing different about putting a m0n0wall behind another, than there is with putting in only one. Your description is vague, do you have a network diagram?

In that diagram, why would you want a second m0n0wall? Do you not control the first one? You can segregate those two networks with the one existing m0n0wall.

Not really :-(
As a beginning, 193.168.0.0/24 is not a private ip range! Though, this might be a typo on the diagram?
Why don't you just use a thirth nic in that m0n0wall as opt interface?(1 nic as wan, one nic as lan for your network, 1 nic as lan for the other network) Unless you want to use CP on both neworks, it's the most easy way to do this.


Kind Regards
Yves

Hello,

there are already three NIC´s placed in the existing m0n0wall. But I cannot acces it. For that reason, I would like to build my own m0n0 behind the other, so there can be no acces from the other subnet onto mine (for I don´t know, how the rules are set up in this existing m0n0wall).

Ok, then to add one where you indicate, given you have no control over the existing one, I would recommend a filtered bridge setup.
