Do you know of a good Linux forum?

Getting more into linux, want to find a dedicated, active forum. Any recommendations?
 
Well, here's my question. Feel free to share any thoughts. I posted it over at linuxforums.org:

http://www.linuxforums.org/forum/topic-53724.html

I'm working on building an Internet Gateway box for a SOHO application, consisting of the following:

-Firewall/NAT/NIDS
-Web/mail proxy
-VPN
-Router/wireless access point

I'm still working out the details of all the packages (squid, freeswan, spamassassin, etc.), but I wanted to get some input as far as hardware goes. The network consists of a varying number of client boxes running Windows, both wired and wireless, as well as a web server (Apache, FTP, mail server with webmail and mailing list) and a file server (samba).

It needs to be small and easily maintainable. Here's my parts list so far:

-VIA EPIA PD 6000E (mini-itx motherboard with dual LAN)
-512mb PC2100 ram
-40gb 7200rpm Seagate hard drive
-Linksys PCI 802.11g wireless card
-Travla C158 90w mini-itx case
-Slimline CD-ROM drive

So, I three hardware-related questions:

1. The board was picked because it is both fanless and has dual lan. However, it has a 600mhz Via processor, which is probably equivalent to a 450mhz Pentium. I'm wondering if it's powerful enough to handle both the software and users. There will be under 50 users on the network, with a maximum of probably 10 users at a time access the Internet and not more than 2 or 3 VPN users at a time. I'll be using a stripped-down Debian installation. I know it's possible to run VPN and routing functions on things like ~200mhz Soekris boards successfully, so I figure this should be plenty for my application. Yay or nay?

2. Based on those requirements, is 512mb ram too much or too little? If I can get away with 256mb, I'll do it, but I'd rather get more than less. The board only has one ram slot, and getting a gig is much more pricey than 512. So, 512mb seems like a good number for both now and future expansion. Does that sound right?

3. I don't have experience setting up a Linux PC as a wireless router. I picked the Linksys because I know I can at least get away with running it using ndiswrapper. I might have to get a PCMCIA card instead and use a PCI adapter to make it work, however. Anyone have experience in this arena and care to recommend a card and/or setup?

Thoughts?
 
Depending on clients and necessary bandwidth. Here are a hint or two about each of these machines, IMO:

-Firewall/NAT:
Almost anything will do. Get something cheap, but decent.

NIDS:
Focus on memory and CPU.

-Web proxy:
Memory memory memory.

-VPN:
CPU power is probably the most important here.

-Router/wireless access point:
Just get some good NICs. For wired, get SysKonnect gigabit ethernet (even if you aren't using gigabit, they're just the best out there). For wireless, get RALink based stuff. It's also the best around right now.
 
That system would work perfect for what you described. Just stick IPCop on it and you are all setup. Well with the exception of the wireless card. I'm not sure how IPCop works with the ndiswrapper. But sense IPCop is built on debian it should be trivial to get it working.
 
I'm too lazy to look it up, but does that thing feature VIA's hardware crypt engine? I'm thinking the "lesser" ITX boards/CPU's don't.
Anyway, the only thing I'd be worried about is the NIDS, that can use up some CPU power.

I've thought of doing something similar to that, though for somewhat different purposes, but I planned on getting the 1 GHz version with dual LAN, then sticking it in a bigger case where a bigger heatsink would fit.
With a decently high end heatsink even their 1 GHz chips won't have any problems running fanless, and you'll have more than enough CPU power, along with another DIMM slot, not to mention some more space for stuff like a 3.5" hard drive, etc.

Of course, that plan only works if space isn't a major consideration.
 
gentoo has (imho) the best fix stuff forums....maybe because we break stuff alot? I don't want to hear it from you anti gentoo folks, we like our distro!

Yes, Gentoo has the best forums that I know of for linux support and most of the information that isn't portage specific can be applied to most any distro.

Everything will work for your needs except the Linksys PCI card. I have that card an No linux will use it without the mentioned wrapper. I would use www.smoothwall.org for your build and there is an iso on sourceforge that has all the current updates on one cdr image that will even do intel gigabit. It does vpn just fine and the interface is very similar to a linksys router. For wirless I would just stick a switch behind the router and run your network off that and put a WAP on the switch. You will want a seperate 192.168.X.X for your wirless network anyway.

My smoothie runs a

350Mhz PII Dell Optiplex GX1
256mb of ram that is WAY overkill ( 128 is overkill actually )
Integrated NIC for my dsl line
Intel 10/1000 pci nic going to the switch ( overkill but i have the card )
6gig HD stock
24x CD-ROM stock

I'm a fedora user, but I have to admit the gentoo folks are very friendly and helpful over there.
