Router + Firewall + NAT = ???
-
My router (ZyXEL Prestige 660HW[^]) has firewall and NAT functionalities. I'd like to run a web server on a PC in the LAN, directly connected to the router. Servers like Remote Desktop Connection and others run fine (I mean they are reachable from the Internet), but there is no way to get an HTTP server running, even changing the incoming port. I've also tried the procedures described on the ZyXEL website, but without success. NAT and Firewall are also properly configured. Does anyone noticed the same behavior on other routers? Do you have any suggestion? ___________________________________ Tozzi is right: Gaia is getting rid of us. My Blog [ITA]

Yep. A lot of ISP block the port 80 for SOHO broadband offers. Try to move your Web Server from the port 80 (use, e.g., the port 3784), and see if it works. If it works, your port 80 is blocked by your ISP.

The link is broken (to many http://) ZyXEL Prestige 660HW[^] Have you check with your ISP? They may have HTTP servers blocked.

I've already tried... :sigh: I think there are some strange options in the router but I cannot figure them out! The user's manual doesn't help about this. In the faq section of their site I've found a document explaining how to setup a webserver as I need, but it doesn't work. At the bottom of the doc there is a statemand that says there are some filters preventing HTTP to pass-through correctly, so they have to be disabled, but it doesn't tell how! On the users' manual there are not hints about those 'filters'. ___________________________________ Tozzi is right: Gaia is getting rid of us. My Blog [ITA]

They blocks only SMTP servers. Port 80 is clear. ___________________________________ Tozzi is right: Gaia is getting rid of us. My Blog [ITA]

Does the web server work from within your LAN? Is there a software firewall active on the server? (WinXP firewall perhaps?) Does the server have a static Ip address, and have you forwarded port 80 to the machine in your router setup? Try disconnecting the router and connecting the server machine directly to your DSL/cable modem and see if you can connect. You'll know for sure it's a router problem if it's successful.

I've not checked because, frankly, it's lunchtime and I'm hungry. But have a look at portforward.com[^] - it's a handy site that shows how to set up routers to allow various bits of software. Not sure if it has your router listed, but I know it has mine (a d-link jobby). I realise that you probably already know about the port-forwarding of your router, but it may help. And it's a useful site anyway.

The webserver works fine (IIS 5.1). I've a dynamic IP address, but the router supports DynDns.org and it's currently enabled. Other servers (on other protocols) work.

The router and the DSL modem are both on the same ZyXEL router... ___________________________________ Tozzi is right: Gaia is getting rid of us. My Blog [ITA]

Thanks for the time I took from your lunch! Port forwarding already runs for other protocols (Remote Desktop and other that I cannot mention here) to the same machine that hosts the webserver (IIS 5.1). That's the strange thing: with other protocols and ports it runs. ___________________________________ Tozzi is right: Gaia is getting rid of us. My Blog [ITA]

Yea know, this sounds more like a DNS issue than a router issue. First question can you access the website on the LAN? Where is your DNSing done? You will need to register the site with an external name server. It can take up to 48 hours for the DNS to propagate out. In another post you said you have Dyna DNS, every time your IP updates you will need to update your DNS records to reflect the new IP. Hope this helps.

I've subscribed a service on www.dyndns.org[^]. The router automatically updates the account with its external IP Address. Thanks anyway. ___________________________________ Tozzi is right: Gaia is getting rid of us. My Blog [ITA]
