Thanks chaps ! I just bought a book 'Networking for dummies' - might have a glance at that. course, it'll give me a headache, then I'll get the router !!
Router's/modem's builtin firewall is easier to set up, but software one should be more flexible + the ability to change the settings-on-the-fly. In case of router f/w any change of port forwarding requires to redial the adsl line. But once you set the router up, there's a good chance you won't need to touch it. At least here it is so (I have 3 machines on the router, two linux boxes have ssh daemons listenening on port 22 and 23, one allows incoming X11, nothing is forwarded to A1. Everything else is closed) If there'll arise a need to change the settings without hanging up, I'll have to get grips on the software one:
sys:Documentation/IP-Filter/ (I think OS install puts it there)

I take it that basically applies for Cable as well (I'm not on ADSL) except for re-dialling, as Cable is just a basic Ethernet connection as far as Roadshow is concerned.
Is there anything I can read online about configuring this, or do I have to wait til I'm back on a proper computer (currently at work on my ex-pee box!)
Cable box lan side is ethernet (probably with dhcp). In case of setup without modem the way to set "non-software" firewall is inside the box. The box itself usually has a web inteface accessible from lan side. I guess pointing your web browser to the IP address of the gateway is the way to access the interface (http://whatever_the_numbers_are). The tricky bit is to find the admin authentication data (start with combinations for username/password like: Admin/Admin admin/admin root/admin ect.
Or google for the manuals of the specific model (if they are not on some CD you got with the hardware). Or google for forums. Usually there's a limited number of setups that can appear on different devices (they don't reinvent the wheel and several different devices can have same interface)
Once you're in, lookfor firewall, forwarding rules or similar. There's also should be a reset to defaults button somewhere if you screw things.

its just a bog standard cheapo box from Scientific Atlanta, with a bunch of status LEDs on the front, and 4 ports on the back - no reset switch AFAICT... but then its 6 miles awy, and I could be mistaken !

with my Nergear DG384GT no need to redial the adsl line, I can change firewall settings and when I hit the apply button changes are effective.

Mine is LevelOne (yup interesting name). Pretty old (3 years imho). Besides this issue it just works.

Blimey, those things look like they haven't been redesigned since the early 80s!
Anyway, that won't have a firewall on it, you'll need a router as well, then do what Jack suggests.
On mine (a Linksys wrt54gc - yes, it's a cable one) it has a few firewall settings, and options to restrict access to sites/services and forward ports to machines internal to the LAN. The port forwarding thingy is the only bit I ever need to touch (for networked games of Freespace or whatever)

I suppose it has it's own forwarding rules sets (at least here the modem has). And an option to redirect explicit traffic to appropriate machines. I don't see a point to get a router while (according to agafater) there are 4 ports there, means it has router capabilities. The big question is how well will it cope if one bangs a really big forwarding scheme.

yup, thats what I thought ! either that, or its someones' A-level Electronics project...

I probably will - I was just wondering if it was worth saving some wedge by using a software one, and the A1 as a hub.
Looks like you have the "WEBStar dpc2100" model (the one in the link provided by Chris). The ports are: power/RJ45/USB/cable in. Accroding to the manuals, it's possible to wire 2 devices to it. Use RJ45 with A1. I tried to google for web interface info and found this here:

Good luck Jack

cool ! sounds about right - didnt see any manuals - unless theyre on the disk from Virgin Media (didnt look to be honest-no reason to yet!)
I'll give that IP a go this weekend. 1st task is to see if I can get me works laptop to VPN through the A1/OS4 and the cable, to the Work network.
cool ! sounds about right - didnt see any manuals - unless theyre on the disk from Virgin Media (didnt look to be honest-no reason to yet!)
I doubt it, I think there is only software and general docs on the disk.
Didn't notice earlier that you were in the UK, why are VM handing out something like that? My cable modem is tiny (and VM branded too). Are you in an analogue-only cable area or something?

I wont bother to look then. thanks for saving me th'effort

no, digital. it is tiny, I guess they havent got any virgin branded ones in our depot ! our area went digital about 8 years ago. Scientific Atlanta used to do the analogue tv boxes - thats where I recognised the brand from.
PS: just tried putting in the local IP address mentioned earlier. cool ! y'just dont get that with a 56k modem ! (alhough it only seems to be a status/diag site - no config)

Lets hope they didn't reflashed it with a software containing a limited interface (to prevent ppl from doing things to save themselves dealing with configs more complex than defaults they decided on). Any "login" dialog there? Usually one has to authorize to get access to the settings.

nuffin' ! only status stuff - probably locked/reflashed, like you say ! after all even the computer illiterate can get a broadband connection !
