E2500 will not allow port 80 access

[jpowell490]

Hello everyone,

I bought a new e2500 and it is working fine, all but port forwarding.  This is not even close to my first router and I am advanced when it comes to setting these up.  I have tried for days to get port 80 to open up and it refuses.  

Now I do notice that when you access the router setup through a web interface, it uses port 80.  I have forwarded port 80 to the ip address of the device, put in a reservation in DHCP with MAC address, etc. etc. and still nothing.  Heck, I have even turned that specific device IP into a DMZ, and it STILL will not work.

Anyone else having these issues?  For the record, I had an e2000 set up the exact same way and it worked just fine and I was able to access port 80.

Thanks,

Generally port 80 is opened on almost all Linksys home based routers. In your case, I would like to know that for what purpose you want to open port 80 and also let me that how are you checking that it is not opened on the router. Sometimes the router's firewall might also block ports to be opened. You can try to disable the router's firewall by clicking on the following link http://www6.nohold.net/Cisco2/ukp.aspx?vw=1&docid=87795adab27b4bd7a432e03be4e28e8d_17347.xml&pid=80&...

I open port 80 because I use DynDns to update my public IP.  I use port 80 to access a controller I have set up for my saltwater fish tank.  I know it works because I had it working on the e2000.

I have noticed that when you access the advanced panel on the router through a browser, it uses port 80 as well.  I think that is what is blocking it.

I turned off SPI and also opened HTTP and put the static IP in of the device I want to forward it to.  Nothing.....This router is about to go back to where it came.

Try to disable the UPnp feature in the Router setup page under Administration tab.... Then check the connectivity status whether it works or not...

Thanks for the reply. I did that and it did not work. I also disabled the NAT and that killed Internet connectivity for some reason. I was able to log back in locally and re-enable NAT and the Internet came back. Very strange router.

Let me know the current firmware version in the Router? If the firmware in the Router is an older version then upgrade it with the latest one which can be downloaded from the Linksys/Cisco website. After successful firmware upgrade you need to reset the Router. It is recommended to reset the router once. Steps to reset the router: Push the reset button on router for 30 seconds, turn off the router wait for 30 seconds and then power it on. Power light should blink when you perform the reset process. After reset, reconfigure the router and then check the connectivity status…
