Could anybody gude me through how to set up my voyager to allow access
to my home network from the outside.

1) Assumption that you know the security implications of your request.
2) Need to know your ISP supplied IP address. Ideally its static. If not,
you need some way of knowing what it may be (eg. dynamic DNS service).
3) Look up the 220v manual for DMZ and Port Forwarding. You are attempting
to forward requests from outside to a specific machine on your home lan.

Assuming that your external ISP-supplied IP address is static, you will need
to set up an inbound port forward rule (eg for port 80 web traffic) to the
IP address of a PC on your network. This PC will also need a static IP
address, either by setting it statically at the PC instead of using DHCP or
else by using address reservation on the router's DHCP server so the PC is
always given the same address by DHCP.

Thanks, I have a dynamic IP from BT, but i do know what it is and can
update as it changes ( does it change? and when)

yes i have a fixed IP on my network that i want to access.

Is the manual on disk? cant see it in my discarded packaging ( i know
RTFMS)

thanks.

It is usually pretty simple from the web based admin screens:

You need to select a port to 'pass through' say (bad example0 you wan to
telnet into a box on say -192.168.0.20..

you need to set pass through for port 23 to machine 192.168.0.10: , on
port 23. for example.

Yu MAY also want to mess with firewall settings so that port can ONLY be
accessed from a range of IP addreses. Not sure what the Voyager
capabilities are.

This sort of stuff is usually online if you google 'BT voyager pass
through port redirect' or something

Try here

http://www.thinkbroadband.com/hardwa...yager2100.html

Its a pece of cake. You don't even need to know what the ports
ARE...just selecet the 'service' you want and the machine address its to
be forwarded to.

That page suggests that there is no inbound firewall apart from the NAT
itself - thats fairly common on most consumer routers so once you set up
a pass through its globally accessible.

Strangely enough my ageing D-link seems to do better. AFAICT it
implements a firewall on packets going in *and* out.

Thanks for that will have a look later

one question, what port and why?

i am tying to just get access to one machine so that i can help my
partner when she loses everything and blames the PC...to be able to
search files and hopefully run one application...

the application is a POS database --

Oh You PROBABLY want one of those remote console programs so you can
operate her machine from afar. Distinctly dodgy that.

The way these work is usually that you ask her to run something on her
machine, then you connect with a name and password,she agrees to the
connection, and you can then run the machine totally remotely.

I forget what its called, or what port its on. But its very common for
managed sites of PC's.

The question suggests you don't understand the security problems.

Practical suggestion time which avoids the security holes you are digging:

Option 1)
Get some backup software which can FTP the backup to a remote server.
(Acronis True Image will do it, I use that for my home machines, and I guess
many others will do the same).
Put the backups onto a server (eg. your webspace which came free from the
ISP, or buy some cheap webspace somewhere).
If/when stuff is lost, use the backup software to recover the files to
whichever computer you wish to restore.


Option 2)
Assuming its Windows, when problems occur, setup remote desktop help to
allow external connection (only turn it on when problem occurs). This
should not need all the port forwarding stuff.



The link given by "the natural philospher" was to a Voyager 2100 article.
Its close enough to the 220v functionality to be useable, but note that it
is a different device and there may be small differences in implementation.

I'm not sure it's possible on a Voyager router.

However, I've been using some Edimax routers recently, and these are very
good value. See:
http://www.scan.co.uk/Products/Produ...oductID=584405

These provide:

1) DDNS client - so you can always find out your ISP-dynamic address from
elsewhere.

2) Access control option - so that you can nominate those IP addresses from
which you want to allow remote access (good for security!)

3) Port forwarding - so you can specify which application you allow to
communicate with the "home" computer.

4) DHCP pool summary - so you can identify the internal computer for which
you wish to set up port forwarding

.... as well as all the basic features you would expect.

Many more expensive routers miss out on some of these features.

It would be nice for it to have a built-in ping facility so it could test
connectivity to a local PC, for example.

VPN support would be nice, but a little too much to ask for £19.29, I think.

or should i just change the voyager for a router capable of VPN?

i was looking at the Linksys 8port and VPN slightly pro one
