Bits & Pieces for Linux firewall?

I see three problems.

1. You probably accepted the certificate from the CP first time around - it's https, remember. So after re-installing your browser gets a new certificate for the same machine, and refuses it thinking something fishy is going on. If you accepted it permanently, you're screwed - I haven't figured out how to fix that one yet (not that I've tried to hard). Otherwise simply restarting your browser may fix that. FireFox is particularly picky about this.

2. You cannot have the two interfaces on the same network.

3. DHCP. If your APN is a router it's probably responding to DHCP requests. The GREEN interface will also be responding to DHCP.

Lastly regarding RED. Setting it to ADSL means you want Smoothwall to do the dialling (assuming it works the same as IP-COP). You need to set it to static or whatever sounds similar - as if you're connecting via LAN to your ISP. Because you're connection via LAN to your router. The fact that it's ADSL at that point is irrelivant. It could just as well be IP over 3600 baud IR.

I just selected "Proceed to website (not recommended)" when that error page came up and didn't accept the certificate permanently. But now that you mention it, there was this java certificate that came up for one of the options in the control panel that I accepted permanently. So that's probably the reason.

That part has already been sorted out.

That would explain the disappearing IP address.

The manual has the following options:

Green (Red is modem/ISDN)
Select if SmoothWall Express will use:
• a network interface card (NIC) to connect to the internal network it is protecting
• a modem or ISDN card to connect to the Internet or external network.

Green + Orange (Red is modem/ISDN)
Select if SmoothWall Express will use:
• a NIC to connect to the internal network it is protecting
• a NIC to connect to a de-militarized zone
• a modem or ISDN card to connect to the Internet or external network.

Green +Red

The connection from the ADSL router has to be set on the RED interface from my understanding of the above:confused:.

You want this one:

Green +Red
Select if SmoothWall Express will use:

If you want to use the Purple interface, you need a 3rd NIC. Otherwise just plug it into your switch (and the switch goes in GREEN) and make sure you have WPA2 enabled and DHCP on the AP disabled, if it has it. Using MAC authentication on your AP is a good idea too.
 
I've got Smoothwall working:). I'm getting a network switch today (currently have wireless APN plugged into green).

So how do I enable the other features that were not part of the original install like squid an logging internet activity?

And how do I install postfix?

Calling all Smoothwall gurus:D
 
Post in the community under the same nick if you want to.

Will make it easier to identify you ;)

I post as the same nick there :)
 
In doing the Smoothwall updates again now and noticed this line:
Added the latest drivers for: tg3, bnx2, e1000 and realtek gigabit. Re-run setup program to detect them.
Click to expand...

One of the network cards is the Realtek Gigabit. This is probably what caused the problem before:(.

After update Smoothwall is screwed again.

I logged in as root and ran setup. The Realtek network card doesn't have an MAC address. So I tried to redect as the update message had said. When I probe it detects the other card but not the Realtek one. I tried to select manually but it comes up with an error:
Unable to load driver module.

WTF:mad:

Edit1: Even restoring a backup doesn't work:(.

Edit2: Complete reinstall and retored config and I'm back up again:). Those updates are bad news:(.

My Smoothwall went loony a few weeks back --> nothing on the green side can access the internet, nor can the Smoothwall update itself or even register itself (after a re-install) :(.

Strange thing is it was working perfectly the day before the problem started:confused:.

I have already re-installed about 5 times and tried setting everything up manually again as well trying a stiffy with previous settings - still doesn't work:(.

Looks like this is the end of my Smoothwall experience.
