A few questions about networking

Hello,

First off I'd like to start by saying i'm not that experienced when it comes to network devices; the only experience I have is with setting up my home network.

Alright so heres my question.

I currently have a pfsense box set up as a router/firewall and I'm running into a few problems.

The network setup is like this: Dsl come's into the modem from my ISP, from there it connects to the WAN port on my pfsense box. I have a single connection on the LAN port from the pfsense box going to the WAN port of my d-link router running dd-wrt. Currently, the Pfsense box has DHCP running, and so does the dd-wrt box. All my network devices (PCs, NAS, laptops, etc) connect to the DD-wrt box. This is because I only have a two 10/100 cards in the Pfsense box (this is fine, my isp only gives me 5Mb/s) and I use the dd-wrt box as an access point and it has 10/100/1000 lan ports so I can access my nas quickly.

so, Should I change the settings on the DD-wrt router so that it's just acting as a switch, and just let the pfsense box assign ip addresses?

Also, I followed everything Logan and Qain said in the video, and I'm having a couple problems.

ClamAV is preventing me from downloading any windows software, saying the executable is broken, even if it's just something like VLC or open office.

I have a hard drive hooked up, but the caching proxy doesn't seem to be storing anything.

Snort is not giving me any alerts at all. I'd like to think that's becuase there's nothing to find, but that seems very unlikely.

Any help at all is appreciated. Also, I hope this post is in an appropriate catagory.

Hey I have a very similar set up and I must say I know for sure you need to turn off the DHCP Server on the DD-WRT box. Just make sure you set the IP address of the DD-WRT box to something in the rage that the Pfsense Box is dishing out. so if you have a 192.168.0.1 make sure it’s something like 192.168.0.20 so that way you can still access your DD-WRT box after you turn DHCP off. This may help your other issues because I'm surprised you can even get Internet access with two DHCP servers on the same network to be honest. Give this a try then let us know if other problems still persist.

What your saying makes a lot of sense. The one thing I'm wondering about is should I have the Pfsense box connected to one of the DD-wrt box's LAN instead of the WAN?

I did some poking around and found I had three DHCP servers running: one in pfsense, on in DD-wrt, and one in the modem for some reason. I fixed all that now, only have one, DHCP server running (in pfsense), pint is way down, speed is up, but I still have the other problems. Maybe something isn't configured properly? I'll do some poking around forums and manuals. Thanks for the help.
