[Help Me] Need help opening ports on DIR-632

What ISP service and Make and model modem do you have?

My ISP is Comcast and my modem model is Motorola SB6120 but as I stated, this combination has already been working fine. All I did was change routers at this time.

I would try using Virtual Server instead of PF as see if that will help.

Double posting

Looks like my reply didn't work the way i expected either.

I tried that and still no go.

Here is what i put in there. See if i did it right.

Well first lets discuss the difference between Virtual Server, Port Forwarding and Application Rules, as I know it.

Virtual Server- Single forward of a inbound WAN port to a LAN port on a certain IP. WAN and LAN port can be different. Common example would be to forward WAN 8080 to LAN 80 because port 80 is blocked by your ISP.

Application Rules- Single port opening of WAN port on LAN port trigger. Notice that's opening, not forwarding, so the session has to be established LAN side first and tracked by NAT as normal. This is most commonly used when only the firewall of the router blocking your application and you want UPnP to dictate NAT.

Port Forwarding- Multiple port forward on inbound WAN to LAN port of a certain IP. WAN and LAN port have to be the same. Used alot in online gaming.

So with that said, I would suggest port forwarding. Maybe if you have issue, also set up a Application rule for port 67, but everything else will be inbound only. The DVR is not going to be making any outbound requests. **The important part is you set up a DHCP reservation for 192.168.0.103 ** if your planning to forward those ports to that IP. Its possible that your DVR is set static to 103 but your router has already given out 103 to another device. Also make sure you can access the DVR locally using the 103 IP. If not, no point forwarding to it.

Last, I checked with Comcast and they seem to block Inbound port 68 (see link below). Maybe the filters hadn't loaded on the modem until you rebooted it after hooking up the new router, but that port isn't going to work. So you can either change the port on the DVR, or change it on the application and then use a Virtual Server rule to forward what ever public port you choose to private port 68. Make sense?

Well, I got some of that but not all. I'm an auto tech by trade and networking has never been my strong point.

What i do know

This is set up on a LAN

Local networking is fine. I have reserved that IP for the DVR and the DVR is set to static IP and everything works fine on the local network. I don't know how long Comcast has been messing with that port but I installed that modem about a year ago and it has worked fine.
I think the DVR does send out for some things like time synchronization.

This part is pretty much greek to me.

"Application Rules- Single port opening of WAN port on LAN port trigger. Notice that's opening, not forwarding, so the session has to be established LAN side first and tracked by NAT as normal.

I made an attempt at port forwarding and posted that in my first post. Can you see anything i did wrong?

Well I was just describing the differences between the 3. I guess it doesn't really matter, in the end you should just use port forwarding. I would first bypass the router and try that to make sure it isn't a ISP issue. I know Comcast has a way of changing what ports they block and with little notice. Also, are you normal Comcast? Or Business class Comcast?

::Edit:: I think what may have thrown you off is my liberal use of WAN and LAN. WAN= Wide Access Network. LAN= Local Access Network. WAN is everything outside your network (internet) and LAN is everything inside your network (computers and DVR). Also ports are like pipes in your house, there can be ones going in (town water) and out (sewer). For instance, port 80 is for HTTP or internet. When you go to a website, you sending a HTTP request on port 80 to the server that site runs on. Some ISP block port inbound 80, but that is only blocking the inbound requests other people are sending you, not the outbound requests your sending for web pages. So thats the difference between inbound and outbound ports. Make sense?

I'm normal Comcast.
Going direct to the DVR would be quite difficult as the modem is on the opposite site of the room from the router with a cable routed around the ceiling and a good distance from the DVR also.

Well then you have to assume port 68 is being blocked by Comcast, as per their own support site. Which means you either have to change the port on the DVR it uses for "data" or change the port your DVR software is using offsite. If the later, you then need to set up Virtual Server to forward what ever port you pick on the software to forward to port 68.

reply to Desi501
Well first there is the issue with port 68. See above.

Second, you cant use application and forwarding. You just want to use forwarding. Other then that, the way you set up port forwarding looks correct.

OK, I'm away from home at work but I will try this when i get home this evening. What should I change 68 to? anything in particular?

I want you thank you for all your help. I do this same thing on auto repair forums. It's nice to have help available.

Well your best bet is to keep it simple, just use port 67, since that is also used for Bootstrap Protocol, which is what 68 is for. But other then that, you just don't want to use a port something else may use. I cant figure out why the DVR would use it for that matter. I think it may not be required unless an advanced setup, but since I don't know, its better to be safe.

Do you think your going to change it on the DVR or the Software?

reply to Optimus2357
OK, I gave it a try. I went into the DVR and changed port 68 to port 69 and then I set the port forwarding as shown below.
I still can't get through from the outside and it added some aggravation on the local level too because my log-on window defaults to port 68 and I have to change it every time, and that has to be done a couple times because of another issue I have had all along in that when logging on locally, it can't access the player on the first try but if I go through the motions and get the error window, I can then reload the page and it always works the second time so that means I have to change the port twice to finally get logged on locally. Still no luck from the outside though. What do you suggest?

reply to Optimus2357
Apparently my post was on hold when you posted. I tried changing the DVR to 67 also but it won't let me. It did allow 69 but my previous post tells what happened when I did that. I have since tried 70 also with the same results as 69.

Thank you again for the help.

reply to Desi501
When your trying to remote in, your using port x.x.x.x:68 or in this case, now your using x.x.x.x:69? If so...why? Should be using x.x.x.x:80 should you not? What DVR is this? I want to check their support site and manual, because I don't see why they are even using port 68, nevermind for remote viewing. Odd.

Ok, First I found this in the manual, page 62.

Note: If the Control Port or Data Port is not available or accessible during
remote access, the system will reset the ports to their default values, i.e.
67/68.

So there is two problems here, one the DVR automatically scans to see if a port is open, and if not, defaults to factory. That could by why it wasn't letting you change it. Second, one of the default ports was blocked by ISP. That begs the question...how did it work before? I think I am going to go back and make the suggestion of bypass and go direct to modem. If you have a ethernet from router to DVR, why not just use that to go modem to DVR?

Also..who is the manufacture? The menu mentions only data and control port, but some videos I found online mention the ability to change the web port (80). I am wondering if it needs a software update...but I cant find the DVR's support site.

Overall I have a gut feeling I don't think I will be able to help with this one. Sorry.

It doesn't have a support site. It's just a Chinese generic import that a company sells online. The last time I set it up, the tech guru from the site I bought it from accessed my computer by remote and set things up. When I moved the system from my business to my home, I simply hooked up the router and it still worked even though the ISP went from DSL to cable. Since it was a wireless G system, I wanted to upgrade my network to wireless N and here I am. I'm seriously thinking of just going out and buying a Linksys so I can just copy the settings from the old one. Someone else told me that D-Links are a real pain to set up porting.

Could it have something to do with the routing IP setuo in the DVR?

I attempted to rig up something to the modem but if I do that, none of my computers have internet access any more to test it. I also think that opens up a can of worms with all the static IP configuration in the DVR I expect I would have to change to make it work that way.
