Hi, i'm a newbie in this. I managed to set up my prima-plastic.dyndns.org account and it manages to link to my DSL Modem. But i cannot access my DVR from here. What should i be typing in the internet browser? It seems like i have to pass through my wireless-N router and then to the DVR. My modem is DSL-526B and my Wireless router is TP-Link TL-WR1043ND. Please Help. Thanks.

Do not select "custom" and "statdns", but the normal whatever it is.
Disable DDNS updates in your DVR. This is useless. You cannot update a WebHop anyway, only a host with IP address.
Gateway must be the IP address of your router (192.168.0.1), not your public IP address.
That looks ok regarding port 24080 to 192.168.0.49, your DVR. Not sure however why you forward port 1000 to your router and port 2233 to Foscam1, the latter may be another device (camera) in your network at 192.168.0.51?
Oops yes, the netmask should be 255.255.255.0. And if your router has the IP address 192.168.0.250, you must change also Gateway and DNS1, these always being the router's IP address.
The netmask must be the same on every device in your network. The typical value for home DSL routers is 255.255.255.0, which means that only the last octet is variable, the rest is fixed like 192.168.0. You should also find this value in your router setup. The setting in the router finally determines the settings in the rest of the LAN.
The DMZ IP address range is outside of your LAN range 192.168.0.1 - 192.168.0.252, so that the networks are topologically separated, as an additional security measure. Given your skills, I would not play with this option, it makes things unnecessarily complicated.
In general, don't play too much with IP addresses and netmasks and such if you don't know what you're doing. Better concentrate on to get your port forwarding right.
Ah, just seeing, I can reach your DVR login page http://prima-plastic.dyndns-office.com:24080/ with no problems:
Starting another answer as that one is getting out of hand again ;)
That suggests you have a software firewall running on the server. If you're unsure how to find out, please tell us the operating system and version number (eg, Windows Server 2003 r2 or Ubuntu 10.10).
This Wikipedia article covers it in detail. In short it's what identifies the network portion of the IP address from the host portion - allowing a computer to identify whether another computer is on the same local network, or whether it is remote (and needs to go through a router).
If all host bits are set (
Netmasks can be any length from
Glad it's all working now.
This guide should help you get started.
I suspect that your modem is actually a router, as that is quite often the case. If the modem holds the public IP, and your wireless router has only a private/local WAN IP obtained from the modem, then indeed the "modem" is a router. If both devices are routers, then you must first forward traffic from the ISP-provided router (modem) to the wireless router, and then from the wireless router to the DVR.

That first response of mine is getting a little long now.
You're not doing port range forwarding. You're forwarding 24080 from your router to whatever port you're using on your DVR. DD-WRT certainly supports that (at least in all versions in the last couple of years).
Can you confirm that you've done one of:
If the latter, what are the first 2 numbers of the WAN IP address of the router (eg
Which configuration are you using just now? Is your modem in bridge mode or are you port forwarding from it to the WAN IP of the router?
Is that as shown by your WAN connected device, or as shown by one of the many web sites? The only value you can trust is the one shown by the status pages on the WAN connected device.
Yes, that will be.
Can you confirm that you can connect to the DVR, from another host on your LAN, using the LAN IP and the port you're forwarding to? Can you post a screen capture of the DD-WRT port forwarding settings and the DVR's LAN IP settings (you may have to use a service like Photobucket, TinyPic or ImageShack)?
What are you using to keep your hostname up to date? Have you confirmed that your hostname still resolves to your WAN IP? Can you post your hostname so we can test remotely?
Well, your hostname is
