    Smoothwall Express Question

    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 <xxx.public.ip.addy>
    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 <public static, eg: 80.0.1.1>
    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 <public static, eg: 80.0.1.1>
    Router internal <none>
    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: <xxx.public.ip.addy>
    Smoothie Green: 192.168.1.1

    that confused me abit tom

    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

    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.

    FN: pick up an AM200 modem and give me a ring/email. Rob or myself will help you through it, or come up with a "how-to" for on here
