Thanks again.
I will try to reset Linksys EA6400 to factory default and set up port forwarding (7, 9 and 1723) again when I get home. And this is the only router that I have now.
Interesting combination of ports you're trying to get setup there. 7 and 9 used in conjunction with each other suggest a wake on LAN setup and with 1723 included it sounds like you're attempting some kind of remote access via PPTP which is neither safe or secure but that's another topic.
Few things to consider here,
How are you testing your port forwards? Are you trying to connect to your router's public IP or dynamic DNS from an external network? Not sure how much experience you have with VPN type stuff but you'll have to do any testing from a network external to your LAN. I'll sometimes hotspot my phone when I find myself in such situations.
Is the internal device you're forwarding to configured for static IP or a DHCP reservation? Some routers will not port forward to a device with a purely dynamic IP assignment.
Other thoughts to consider,
Have you considered perhaps moving to an IPsec based solution? If you're just trying to connect from a single device that moves around frequently this might not be easy but works great for creating persistent connections between 2 networks and is far more secure.
Few questions remaining still,
PC1/2: Do these PC's use static IP's or DHCP and if DHCP, are they setup with reservations?
WOL: What destination are you sending your WOL requests to? Is is the public IP address of the router or are you using some sort of dynamic DNS solution.
Hello Everyone,
I did the factory re-set Linksys EA6400 after removing all the PCs and other devices from my LAN environment.
Finally, port forwarding is working as expected.
Thanks everyone for making various suggestions!
Happy port forwarding!
Hello, thank you for your comments.
I have been using like this for a long time:
PC 1: ports 7 and 1723, When there was a power outage, I can wake it up with port 7.
PC 2: port 9, I wake up this PC 2, so I know that the port forwarding is always working.
I also use web site such as: canyouseeme.org / yougetsignal.com and there is an app on my phone to perform WOL, scan ports, ping, LAN device scan, etc. as well
Linksys EA6400 is set with DHCP and dynamic IP when it was on ATT network and it was working.
I also have a similar setup in my small office with D3.1 eMTA modem + Linksys E2500 on Spectrum network, and port forwarding is working.
I don't know who makes this D3.1 eMTA modem and Spectrum does not provide the IP address for this D3.1 eMTA modem. It is just a straight-through modem.
Now, I am going home and check Arris S33 + Linksys EA6400.
Hello Everyone,
Thank you for your various suggestions.
I re-set Linksys EA6400, but the port forwarding is still not working.
So, this is the observation so far:
Arris BGW210-700 to Linksys EA6400 on ATT network - works.
Arris BGW210-700 had bridge mode in 192.168.1.254 as this is a modem/router combo.
Arris S33 to Linksys EA6400 on Cox network - not working.
As Arris S33 does not have any configurable functions in 192.168.100.1, so I am assuming it passes through everything.
This is very perplexing as Linksys EA6400 is working, I am not sure if there is anything incompatible between Arris S33 and Linksys EA6400 in terms of certain functions.
Can you test if the port is open with a direct connection to the S33? Or do you need multiple computers to make it work?
Having taken another look at your previous device, it would appear it was a gateway of some sort. I'm now wondering if you're seeing hangover from previously having a double-NAT setup. In terms of network hardware, the Arris S33 cable modem is classified as a bridge which once provisioned, is completely transparent to your network. This permits your Linksys router to obtain a public routable IP address. Traffic sent to this IP address would then be forwarded to internal IP addresses in your network based on what port the traffic comes in on.
Something else to check: Do you have any router logs showing the desired traffic reaching your public IP?
I was about to suggest that, is there anything showing that the traffic is even hitting the router to BE forwarded to the right port?
Thank you again, everyone
Yes, PPTP is enabled on Linksys EA6400.
The WAN IP on Arris S33 is showing up on Linksys EA6400.
I think I need to spend some time this weekend to try more things.
Thanks again.
Whatever you are trying to connect with using the port forwarding, has it been provided with your NEW IP address, or is it still trying to get through using your OLD IP address?
Huzzah! I am glad a factory reset worked but I wonder what the problem was?
