HI all,

Network Scenario.

LAN--->>>>>>  D Link DIR 600 L ---->>>>>>>>> Cable ( Modem + Router ) -->>>>> Internet

1.> Cable Modem configured in router mode ( Not in brigde )
2. > Internet is working

Trouble : Not able to open certain ports
I have added the local I P ( 192.168.1.100 and ports to advance port forwarding )


Doubts :
IS it possible port forward only adding forwarding rule to ADVANCED PORT FORWARDING ?

Should firewall rule /  Application server has  to be added along with port forwarding.

any other settings for port forwarding /./ ?

thanks,Anoop

Link>Welcome!

• What Hardware version is your router? Look at sticker under router.
• Link>What Firmware version is currently loaded? Found on the routers web page under status.
• What region are you located?
• Are you wired or wireless connected to the router?

Internet Service Provider and Modem Configurations

• What ISP Service do you have? Cable or DSL?
• What ISP Modem Mfr. and model # do you have?
• Is ISP Modem/Service using Dynamic or Static WAN IP addressing?
• What ISP Modem service link speeds UP and Down do you have?
• Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended.
• Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values
• For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.
• If the ISP modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems: Link>Double NAT and How NAT Works. To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged. If the modem can't be bridged then see if the modem has a DMZ option and input the IP address the router gets from the modem and put that into the modems DMZ. Also check the routers DHCP IP address maybe conflicting with the ISP modems IP address of 192.168.0.1. Check to see if this is the same on the ISP modem, and if modem can't be bridged, change the DIR router to 192.168.1.1 or .0.254.

Hi Sir,

thank you for prompt reply.Router is now at remote location and cant have access.

Firmware i have loaded with latest one.
Located at kerala
Using Asianet internet ( Coaxial Cable Via Cable Modem and the DLINK router )
While configuring i will connect it wired.

Internet is fine.Only problem with port forward.


MY Problem is IS there any other configuration needed other than port forwarding settings in ADVANCED PORT FORWARDING RULE .?

( Is it required to add any firewall rule to allow all //   is there any default allow all

IS it required to add allow all in application filter too >>.))))




Please clarify the hosts connected In DMZ, It will be exposed to outside users of Internet.
How about status of the ports .?


thank you ,

Sir,

thank you for the reply.
My Scenario is double NAT.I port forward the two routers.


Router 1 :

ISP >>>>   (  ROUTER 1 )   >>>>> 192.168.0.X >>>>>>  ROUTER 2 >>192.168.1.X>>>> LAN


ROUTER 1.
WAN :  IP PROVIDED BY ISP
LAN : CONNECTION TO ROUTER 2 IP ADDRESS 192.168.0.1
PORT FORWARD : 1234 PORT >>>. 192.168.0.11
DYNAMIC DNS CONFIGURED


ROUTER 2
WAN : IP ADDRESS   192.168.0.11
LAN IP : 192.168.1.1
PORT FORWARD : 1234 PORT >>.  192.168.1.100


LAN CONFIGURATION ( PC/SERVER )
IP ADDRESS : 192.168.1.100
GATEWAY : 192.168.1.1
DNS : PUBLIC DNS / ISP DNS
PORT OPEN : 1234


PORT FORWARDING WORKS FINE NOW.


I CONFIGURED DYNAMIC DNS AT ROUTER 1 : WILL  IT AUTOMATICALLY UPDATE DYNAMIC DNS.
DYNAMIC DNS OPTIONS AVAILABLE ARE DYNDNS.ORG ( CUSTOM )

CAN YOU PLEASE TELL DYNDNS.ORG (CUSTOM) IS SAME AS DYNDNS.ORG PAID ACCOUNT .?/

 
THANK YOU,

You'll need to refer to the DDNS web site on what account features differ or is available. We don't have that information here.

Thanks for sharing your setup information and configuration. I hope this helps other future users.
One other suggestion would be to use the DMZ on the 1st router for the 2nd router as well.

Glad you go it working. Enjoy.
