Hi

 

I am looking at using Smoothwall Express, with an ADSL connection. I was wondering how i would get the connection to the network. Would i use the smoothwall box as an ADSL router? Or use the exiting one in a setup like this:

 

LAN > Smoothwall > ADSL Router > Internet

 

If i use smoothie as the router i take it would require more hardware?

If i use the current ADSL router as well as smoothwall how would i go on with port forwarding?

 

Im pretty new with this type of technology so please bear with me :)

 

Thanks

To use the smoothwall box as your ADSL modem/router directly you would need a compatible internal adsl modem in the box. You could use your existing router in one of several ways. The best way (if your router supports it) is to use passthrough/bridging mode which will offer the internet connection as an ethernet connection and there is no interfearence from the router.

 

You could also set it up with a private subnet inbetween your router and smoothwall box (if it does not support passthrough) and set the smoothwall box external interface as the DMZ ip in the routers configuration.

 

Your third option is mapping the ports individually in both the smoothwall box and the router which can be slightly more secure but is a massive pain and subject to the stability of both the router and the smoothwall box to function.

Ive got my smoothie setup with 2 interfaces (RED (External), Green (Internal))

On the red interface i have my ADSL Router and the smoothie, and on green is just all the network traffic.

 

It is possible to setup the smoothie with a usb modem or internal one but i find it easier just setting the default gateway on the red interface to the router.

Hokay... most "normal" folks :) do set up one red, one green NIC on the smoothie, and then either "double NAT", or, if they have more than one IP, assign the router one, and the red nic another. Alternatively, some routers will "bridge" an IP, and some internal ADSL modems are supported

 

 

So you have one of the following setups:

 

Filthy double-NAT:

Goodness: Low

Number of public IPs required: 1

Works w/ dynamic IP: Yes

Disadvantages: sucks for external services - either pf or VPN.

 

Router ADSL

Router internal <10.0.1.1>

Smoothie Red <10.0.1.2>

Smoothie Green <192.168.1.1>

 

 

Routed:

Goodness: High

Number of public IPs required: min 4

Works w/ dynamic IP: No

Disadvantages: few

 

Router ADSL

Router internal <80.0.1.1>

Smoothie Red <80.0.1.2>

Smoothie Green <192.168.1.1>

 

Bridged IP:

Goodness: Medium

Number of public IPs required: 1

Works w/ dynamic IP: Yes

Disadvantages: pig to steup, only a few modem/routers work. Linksys AM200 is one

Router ADSL

Router internal

Smoothie Red <80.0.1.1>

Smoothie Green <192.168.1.1>

 

 

Internal DSL:

Goodness: pretty good

Number of public IPs required: 1

Works w/ dynamic IP: Yes

Disadvantages: extremely few modems. Bewan is one. no ADSL2+ support

 

Router: None

Smoothie Red:

Smoothie Green: 192.168.1.1

 

HTH :)

that confused me abit tom :o

 

so my best option would be Filthy double-NAT.

 

does that work like this: LAN > Smoothwall > ADSL Router > Internet

 

sorry to sound stupid about it.

 

thanks

FN - sorry, it's a "double monday" today, and my brain is on a go-slow :)

 

If you have only one public IP, double NAT is an OK option. It will work as long as you don't want to do much in the way of port-forwarding & VPN. In this case your "diagram" is right, yes :)

 

Otherwise go for either a BeWan modem (if you only use ADSL1) or a Linksys AM200 if you have DSL2.

Hi

 

only one public IP and will be doing some pointing for VNC & RDP every now and then. Possibly a websever in an orange zone & some light VPN use.

 

What is the proxy like in Smoothwall express 3?

 

Cheers

Hey Guys,

 

Well i kind of get the was to do it now but with an ADSL line, what if it was a DSL line. as thats what i have.. and was thinking of doing the same

 

How would i go about doing that also.. it is possible right?

 

James.

SDSL is similar, only with the proviso that internal DSL modems are still shonky for it.

 

FN - you should be ok double natting, but for preference i would try something like the linksys AM200 (only 20 quid) so you dont have to.

Ok thanks, how much of a big is it to setup?

Hi tom

 

Do you have any guides for setting up this method please?

 

Bridged IP:

Goodness: Medium

Number of public IPs required: 1

Works w/ dynamic IP: Yes

Disadvantages: pig to steup, only a few modem/routers work. Linksys AM200 is one

Router ADSL

Router internal

Smoothie Red <80.0.1.1>

Smoothie Green <192.168.1.1>

 

Cheers, i appreciate it.
