Please, look at my previous question.... Does the answer you have given to Aeron Robinson apply to my question too?? If it does, how can I "assign 2 public adresses to m0n0wall (1 to the WAN and one to the LAN interface), which have to be in 2 different subnets"? Can you show me steps? And how can I use m0n0wall in bridge mode (steps)??

Hi Aaron, if you're using routable ip's you can enable enhanced NAT and don't create any specific rules. This leaves NAT out of the picture, because you don't need (or even want) it. If you want to do the public address routing, you will have to assign 2 public adresses to m0n0wall (1 to the WAN and one to the LAN interface), which have to be in 2 different subnets (a bonus would be to be able to put your isp's router in bridging mode, so you could use its 'outside' public adress for the WAN interface). If you cannot change the ISP's router config, then maybe you should use the m0n0wall in bridging mode (with the patch), so you will not loose your precious public IP's in an unusable subnet outside your firewall. To stop people from using a non-assigned but valid address, the only thing you can do is block all traffic in firewall rules for these adresses, but that wouldn't prevent a user from 'stealing' a registered address from somebody else (who'se PC is off for example). A switch supporting VLANs would help, but then again, it would get a mess to maintain. Another solution is PPTP, but you will need authentication, which you would like to avoid, as I undestand. DHCP and ip configuration for the clients will be very simple. Just put your ISP's router as a gateway in m0n0wall, and all traffic will find it's way (as the m0n0wall will be the default gateway for your clients)... I don't know hpna, so there I cannot assist you...

I've used m0n0wall personally for a bit and like it. It runs great on my P133 with 32MB RAM. However I now have a larger project that I am trying to help with. I am new to routing and am sure I am asking a simple question. If anyone has some recommended resources where I could learn more about what I'm asking, I would appreciate it. I am trying to set up a network that will have routable IP's. I will have a block of 16 initially and more after I figure things out. It will be for internet access at the condominiums where I live. Unfortunately my experience with networks is limited and I have never used a network where I had more than 1 IP. The LAN portion has always been NAT'd. What I am tying to figure out is how I would set up something like m0n0wall for routable IP addresses. Everything i've worked with in the past has been with NAT. I want to be able to assign people routable IP's via DHCP. What would the m0n0wall LAN IP be? DO I use the m0n0wall computer as the "router" IP on all client machines? I'm not quite sure how I would direct all traffic through the m0n0wall. Network topology is cat5 to all of the buildings and then HPNA into the units. The HPNA concentrator is essentially a switch where I can turn on/off units but not much more. There are 40 units total and our connection is a 1.1Mb SDSL line. DSL router is an Efficient Networks Speedstream model 5851. ISP | DSL router | m0n0wall (not implemented yet) | Switch ------------------------------------- | | | | hpna1 hpna2 hpna3 hpna4 ||||||| |||||||| |||||||| |||||||| individual units So what I am looking to have it do is 1) Stop people from using certain ports (25 is one) 2) Limit bandwidth. (looks easy enough in the shaping. Are there implications?) 3) Assign static DHCP addresses (seems easy) 4) Block people from putting multiple computers on without registering them. - I don't care about someone with a box doing NAT....I just don't want people using up IP's. Can I prevent them from just putting in a good (for our network) but unused address? Or how would I prevent an IP to be assigned to someone who hasn't registered their IP? I don't want to have people sign in or anything... 5) Any suggestions on what we could/should do to make things more secure or operate more smoothly? I don't want to NAT people since they will be paying for service. However we don't want to allow people to run mail servers etc. and perhaps should block a few well known p2p ports. This would be possible with routable IP's correct? Do I just leave NAT off? Will I be using static routes? I'm really not sure how this would look. If anyone was willing to share some knowledge to get me started in the right direction, I would appreciate it. I can send beer :) Thanks!
