This isn't really a Linux question but it is network/computer related so it's not that far off topic.
We've just got ADSL and I'm now up and running with a Zyxel 660H router/switch.
I would like to be able to configure the Zyxel remotely using the web interface but I would also like to make a Web server on one of the machines in our home network visible to the outside world. Is it possible to do both of these things at the same time?
The Zyxel has a specific menu for setting up access to the management interface, you can enable/disable the telnet and HTTP interfaces for LAN or WAN or LAN & WAN. You can also set the port number associated with these.
In the NAT configuration you can set up services on the LAN which you wish to be visible to the outside world.
However I don't see how one can have a web server visible to the outside world at the same time as making the management interface visible as they will both appear as the same port number and IP address.
I tried changing the port number for the managment interface access from the default 80 to 8080 but that just stopped it working completely because the firewall at the other end wouldn't pass traffic on port 8080.
Is there any clever redirection I can do on the LAN to make it possible to connect to the Web server on the LAN and then to the Zyxel router from the LAN side?
I could configure using telnet, I'm quite happy to do that, but it's hardly secure over the internet. I suppose I can set it so that it's only accessible from specific IP addresses which might be OK.
Hi Chris,
THere is something you could try, but it is really very nasty, and about as secure as anything M$ :-)
Apache has a proxying capability, so you could connect to the web server on your pc, and depending on your url proxy it to the Zyxel.
The thing is this opens up all kinds of security holes, and people start using your webserver as a proxy. I tried using it to talk to the web interface on my Tivo. In the end I just enabled passwords on the Tivo, and set up port forwarding on my linux machine.
My turn for a question now...
Is the Zyxel modem any good? Does it do PPPoA to PPTP relaying? Currently I'm using an Alcatel Speedtouch Pro, using the relaying function so my Linux PC gets the IP address. I was thinking about replacing it with the Zyxel when it eventually dies, not that it's showing any signs of sockness at the moment :-)
