    Re: Broadband connection: RBC NAT versus Public IP addresses

    We have been sorting out a good arangement with our RBC.

    We have our own firewall and NAT internally ... we still have htem NAT some public address to EMBC NATted addresses ... and we redirect those when they reach our firewall.

    We have control of our filters (non-authenticating in pass through mode at level 1 for any traffic that goes through our filewall) and we host our own internal mail and web filters, along with our own webservers and email.

    Just gotta do some changes on DNS this weekend and we will be good to go.

    Re: Broadband connection: RBC NAT versus Public IP addresses

    i find swgfl good in the way it works the only problem i have had is the responce time to a router issue which took nearly 1 wk but filterd email is really good and music downloads also a site called infomapper.com which is free to swgfl is gogle earth plus it has os maps historic maps world maps and you can overlay the lot so i cant moan. Its the extra services that make it worth it.

    Re: Broadband connection: RBC NAT versus Public IP addresses

    Firewall is now a Firebox X700 and we use Smoothwall for web filtering and MailMarshall for email filtering ... depending on how good we find the email filtering over the spring term we may drop MailMarshal. I have used EMF before (Whilst at Brooke Weston) and I really like it ... it takes a bit of tweaking but generally it is spot on.

    Smoothwall has a few interesting issues but Stephen is in conversation with the Smoothwall guys and we hope to iron these out shortly ... it looks like one issue (embedding of movie files in web pages not loading the link properly) is down to a combination of the firewall and Smoothwall ...

    Did you "roll yer own" Smoothwall - or have it installed for you? I'm thinking of having a look at it.

    We bought in Corporate Guardian because we wanted the support and updates for at least the first year ... and it worked out cheaper than Symantec Web Security too.

    Tom and folks were really helpful sorting out exactly what we needed and Stephen (a confirmed non-*nix person) was happy.

    Basically an ISO that we loaded onto one of our Poweredge boxes ... went on very smoothly (pardon the pun) ... and had a relatively easy guide to set it up.

    When we have more time I would like to get to grip with building our own DansGuardian box ... if nothing else to give the rest of the team the experience of doing it.

    If you need a hand with Dansguardian/Squid/etc please direct things at me. I can most likely help.

    Hi Geoff,

    I'm seriously thinking about the Extended Defence+ homebrew version of Smoothie but having loaded it on a spare PC I'm well aware that I'm in over my head with it all..

    Any pointers on where to start and what to read first so I can get to grips with it all... Bearing in mind my primary concerns are:
    - Firewall
    - Guardian Reactive firewall
    - Content filtering (for a primary school)


    I suspect I may go with School Guardian if the school decide to drop the LEA link as the cost/risk element is in favour of an "out of the box" solution with support but I'd still like to learn this stuff for my own benefit.
