Trying to remote desktop over internet to allow remote administration of server. Using Actionec DSL modem (71.x.x.x - ext and 192.168.0.1 - internal)and have Linksys wirelss router connected to it running OpenWRT RC5 (192.168.0.2 - WAN and 10.0.1.1 - internal). Firewall is turned off on the DSL modem (only running NAT) and I am port forwarding all traffic on 3389 to 192.168.0.2 (wireless router). On wireless router, I am port forwarding all RDP traffic on port 3389 to internal address (10.0.1.105). Nodes on internal network (10.0.1.x) are static and need to be so. Port forwarding is not working.
But you get to decide which address space you want to work with, before continuing to do so..
A single Class C network for example 192.168.1.* - up to 254 computers.
A single B Network for example 172.16.*.* - up to 65,534 computers.
Class A network 10.*.*.* - up to 16,777,214 computers. Maybe more if I am mistaken.
Why "before continuing" because each Class of network, has it's own default subnet.
Class A 255.0.0.0,
Class B 255.255.0.0
Class C 255.255.255.0
If you are changing between any one of these three classes to another one, not only do you have to change the LAN IP (example from 10.0.0.5 to 192.168.1.9) address of the device(s) you also have to change the subnet mask.
Fail to? I been there and done it. You be able to release and renew your IP address of your computer, but you are not going anywhere...
While Double Port Forwarding can be done, however it is a challenge and has some other issues to it..
Interesting enough, I did some testing of my network and not only it is possible to double port forward. It is possible to Double DMZ. My choices on how to protect my parents computer(s): All other Computers off, Tripple NAT, or use three LANs in Y config. That looks like this...
d) If your router is not listed here yet, consider submitting it...
*If you can't run RSG, try another method. If you can run RSG but you get errors, you can try another method.*
#1 Download and install the Router Screenshot Grabber. As you browse through your router it will take screenshots of all the pages you visited. Then it will upload those screenshots to their server. They will write a new guide for your router. They have got a pretty fast turn around on new guides.. Usually they have a guide up the day after the screenshots have been submitted Monday through Friday... You can download the rsg from the following link. http://portforward.com/requests.cgi and selecting Router Screenshot Grabber.
Note: If you choose to Download and install the Router Screenshot Grabber, the screen shots are sent to the people who run this site. They should re-edit your pictures for you, so certain info is not seen. Which I will get to in a minute...
Since you have to provide them your e-mail address if and when this device is corrected here, they will reply to you.
#2 Send all of the screenshots to firstname.lastname@example.org
#3 Post all of them in a thread.
However, please don't show the following info:
#1 You full MAC address(es). If you wish to show any MAC address(es), please show only the first three pair(s). Example my first three pairs of my MAC address is 00:10:B5 (also written as 00-10-B5). This info only tells users what is the brand of my NIC (Network Interface Card) is, also maybe the model.
If you show your full MAC address, it tells people the brand, model, and serial number. Not good, unless you like that info public.
#2 Your pppoe / PPPoA user name. It could be in the format of username or username@ISP. If you wish to show your pppoe/PPPoA user name, please only show the @ISP part.
#3 Any serial numbers.
#4 Your SSID, WEP / WPA key, if you are using a wireless router.
#5 Your full "real" public IP address, which will be an IP address outside of those three ranges:
If you wish to show your "real" public IP, please only show the first two octets. For example if your IP address was 188.8.131.52, the first two octets would be 70.110.
