Under Access Control -- Services there's a list with FTP, HTTP, ICMP, SNMP, TELNET and TFTP. They're all enabled for LAN and all disabled for WAN. Is this correct?
yes

When I set up the virtual server for HTTP, a message appeared that said "Since port 80 is used, the DSL router WEB server port will be moved to 8080." I took this to mean that any client outside the router attempting to access the server behind the router through port 80 would have the packets translated by the router to port 8080, and as such, I had the web server listen on port 8080. Should we handle this differently?
This is what our virtual server entry looks like at the moment (if I've used the Insert Image feature here correctly.)

That mean that your again set Internal Port Start/End 80, not 8080 or not apply settings.

If I set the Internal Port Start and Internal Port End to 8080 (rather than 80), nothing changes.
1. there will be no message about port
2. you forward your external 80 of router to internal server port 8080.

Attempting to access the page normally, http://216.123.238.123 , gets me to the login window for the router. Attempting to access it with the port number, http://216.123.238.123:8080, gets a "Firefox can't establish a connection to the server" screen.
Its because you trying to connect from local to internal(lan) modem port 80. You need to use other Internet connection to connect external(wan) router port 80.
From local network 216.123.238.123:80 = lan_modem:80
From other network 216.123.238.123:80 = wan_modem:80 -> forward to 192.168.2.11:8080

Change your Internal Port Start/End from 80 to 8080.
Don't forget when you change something like that - save/reboot modem from menu. Some setting working only for current session.

If you cant access from other internet connection to your web server:
1. Firmware bug.
2. Server not properly configured.

How to test:
1. Run uTorrent
2. Enable WebUI and set port 8080
3. Configure modem
Code: [Select]
External Port Start External Port End Protocol Internal Port Start Internal Port End Server IP Address
Web Server (HTTP) 80 80 TCP 8080 8080 xxx.xxx.xxx.xxx
xxx.xxx.xxx.xxx -your lan client ip with uTorrent
4. Connect from other internet connection to http://your_external_ip/gui/
your external ip http://www.whatismyip.com/
If not work - change external port 80 to 81 and try again. Make sure there are no problems with firewall.

Thanks for all your help - we'll try D-Link's support.

Can I ask you two (hopefully) lesser questions?

1. Once or twice a day, the DSL-520B router goes into vapor lock. Its Internet light turns red, and stays that way. The only way to get back on line is to manually power it off and on again.

I believe it's encountering a momentary DSL outage, which it's not recovering from. (It does successfully recover from most short outages.)

Is there a configuration setting to get it past this issue?

2. Most routers have an option to make their DHCP server's lease time "forever." Is there a way to make the DSL-520B do this?

Thanks again.

Ya, not seeing any DHCP Lease times like on DIR series routers. I would present this to D-Link support as well. If there is a problem with the ISP or signal, this could effect how the modem behaves. It should recover should the signal go down then come back. You should ask your ISP to review there logs to see if they see anything when this happens. Something could be preventing the modem from renewing gracefully and needs to reboot. I would have your ISP check the phone lines to be sure they are properly installed, configured and filtered where needed.

JacksBack,
it was the easiest question. I know for sure it works(in my case with Apache and uTorrent for several years).
I hope you be attentive and do exactly as your local support say. That will be the best in this case :)
And it seems will remain unknown - can your router forward any port.
Or i missing something.

1. You can get info about that in Modem System Log page :)
Also in my case there "Keep alive PPP connection" and "LCP echo interval" settings.
According to this manual http://www.dlink.com/us/en/support/product/-/media/Consumer_Products/DSL/DSL%20520B/Manual/DSL-520B_Manual_US.pdf
There no such options in 520B F/W 1.0 - And 320 and 2500 get them in latests (or earlier) F/W.
But differs from this:
http://support.dlink.com/Emulators/dsl520B/310/index.htm

2. just for information:
DSL-320B/DSL-2500U - Both contain static DHCP list (manual add). Max Leased Time(in hours) is 2^31 value (5879615 years) :D
According to this manual you can do the same (Page 38)

Also pages 41-42 Contain useful information.

I will not take up your time any more.

Awesome info Grem. Thanks for your help on this.

One last resort suggestion if the DSL modem can't seem to be configured correctly, get yourself a external router, such as a DIR series, bridge the DSL modem and then use the external router to handle the PPPoE connection and set up the router for any ports and such for Web Server connections.

I do hope that DLink support can help you get the DSL configured though.

Please let us know how it goes. If they get it going, PLEASE post details and pictures.  ::)
