port forwarding

cinrod · 04-14-2006, 10:03 PM

I have a router capable modem (non-configurable DW7000 for Direcway/Hughesnet) and a linksys wireless router that I have set port forwarding on many times with no problems when it was connected to a cable modem. The new modem has an IP address of 192.168.0.1 and of course the linksys is a 192.168.1.1. The linksys is passing out the IP addresses beginning with 192.168.1.100. I set my ports for Echolink (Ham Radio app) to go to that first IP, and can surf fine. However I can't get a signal back from the Echolink application (times out). I know there is some sort of conflict going on with the networking scheme, but have no idea what I need to change. Bear in mind, I do not have the option of setting the modem to bridging mode since it is unconfigurable. Does anyone have any clue what changes I need to make on the linksys please and thank you!!

If the device from DirecWay is acting as a Modem and router then you don't need to use your LinkSys as a router. Don't use the WAN port on your LinkSYS. Instead connect the DirecWay modem/router to one of the switch ports on your router.

OK....will that still allow me to do the necessary port forwarding in the linksys?

No, the first NAT layer encountered is the modem/router, so that's where you need to do the configuration. The following is the procedure for connecting two SOHO broadband routers together.

Configure the IP address of the secondary router to be in the same subnet as the primary router, but out of the range of the DHCP server in the primary router. For instance DHCP server addresses 192.168.0.2 through 192.168.0.100, I'd assign the secondary router 192.168.0.254 as it's IP address.

Disable the DHCP server in the secondary router.

Setup the wireless section just the way you would if it was the primary router.

Connect from the primary router's LAN port to one of the LAN ports on the secondary router. If there is no uplink port and neither of the routers have auto-sensing ports, use a cross-over cable. Leave the WAN port unconnected!

Johnwill,
Thanks for the info. I will give that a try, but without the ability to forward UDP 5198-5199 and TCP 5200 on the linksys, I get the feeling my Echolink program is still not going to work unless I missed something in your excellent explanation. Remember this lovely Direcway DW7000 is not configurable in any way (grrrrrr). I am on the edge at this point, however and willing to try anything.
Thanks!!!!

If the Directway router is not configurable at all, you are probably out of luck. If it has a NAT layer that you can't forward ports through, the rest of this stuff is somewhat moot. Are you sure you can't put your secondary router in the DMZ of the Directway router? I know nothing about Directway, or the restrictions they place on their service. Did you contact your ISP and ask them?

Johnwill,
Again I want to thank you for trying to help with my frustrating situation. I have tried to set the linksys in the DMZ, still no luck. A phone call to Direcway just left me more frustrated, as they "claim" they are not blocking any ports on customers using the "Home Professional" package with a dynamic Ip address. I also found that their so-called technical skills were severely lacking, and they were not willing to push me up to the next level of support. However, I did find some interesting info on the Echolink Yahoo Group that indicates they DO block ports on the home package even though they don't admit it. Apparently the only fix is upgrading to the "Business" package which includes a static IP address and full access to all ports besides the usual, 25, 80, 110, etc. Hmm nice way to get another $20 a month. Anyway, everything else works fine, it is just the Echolink and VNC applications that need those ports specified for returning packets. Dad is going to talk to the rep today to see what his options are. $600 is a lot of money to lay out for a system that only does a portion of what you want it to.
Again, thanks for your help
Cindy

I suspect that continuing research and pushing the Directway folks is the only recourse you have. I'd try to find other folks that have Directway to see if someone has discovered the secret handshake.

Johnwill,
Just wanted to let you know my Dad and I have FINALLY resolved our port-forwarding issues with Direcway/Hughesnet. The key was to upgrade to a static IP address and reconfigure the linksys with that static info. Both Echolink and VNC are working great.
Thanks for all the help,
Cindy

Glad you were able to sort it out.
