I have a Linksys BEFSR41 router running firmware 1.42.6 and I am trying to forward port 80 so I can run web server at home. I've made sure I have done the following:

- Turned off DHCP
- Assigned a static IP to my computer
- Disabled SPI
- Disabled Block WAN Request
- Forwarded port 80 to my computer's IP

I am pretty sure my web server is working since I can get to it from my own computer. When I try to get it from a computer at another location, I can't. I've enabled logging on the router and it does not show any attempts to access port 80. I have even tried to use DMZ but this does not work either. Any help would be much appreciated. Please let me know any additional info is needed. Thanks.

I had the exact same problem:
-- there's nothing wrong with the router (and port forwarding is working fine).
-- there's nothing wrong with your webserver too.

After long hours of painful troubleshooting, someone else from the Win2k board clued me in to the obvious -- you ISP may NOT be allowing port 80 on their networks.

You will have to set up your webserver to listen/serve on another port (such as 8080) and then configure the Linksys to forward on port 8080 as well. It'll work from there.

If you're accessing by IP, you have to type a longer string of chars (i.e. xxx.xxx.xxx.xxx:8080).

applejacks is correct about the ISP blocking port 80. i work for Time Warner and we do block 80 unless you are a commercial customer. not sure if that is your issue but could be.... good luck

Thanks applejacks and adamr. Your solution fixed my problem. I should have thought about that sooner. I have cable modem service through Charter Communications and it looks like they were blocking port 80. Thanks again!

I have the same problem as Jason. I have a Linksys router and a Linux webserver, only my external IP address points to someone else's website, even when my Linux box is off. I used www.whatismyip.com to tell me my external IP, and when I go there, it's someone else's site. I even tried using a different port, other than port 80 and forward the port through the router. Nothing happens, the page cannot be found.
Any suggestions?

I have a linksys BEFSR41 4 port router. I cant run my apache web server. I have charter communications cable service. Before I got the router it was working fine. I did try port forwarding 80. any ideas?

Email me and i promise you that your web server will work. I will give you detailed directions.

Linksys routers have a definite problem
with all firmware updates past March
2000 1.23 forwarding port 80 packets.

Here is what's happening, it's not your
ISP, it's the router. You access the router
via port 80 and web browser right? When
you forward the port 80 packets to a web
server, you can no longer talk to the router
because all subsequent attempts go to
your web server and not your router.

I've been on the phone 4 times with
Linksys support folks. One guy told me to
buy a new version of the BEFSR41 router
because the old one I had couldn't
understand the new firmware. THAT WAS
A LOAD OF CRAP. I bought the router and
still can't talk to the router after I assign
an 80 to 80 range to a specific static IP
within my LAN.

The funny thing is, you can upload 1.23
and get PERFECT port 80 forwarding
AND you can maintain connnection with
the router itself AFTER you make the
update.

I've sent a detailed description to my rep
at Linksys and she is going to get me a
response from the firmware
programmers.

Keep your kidney's crossed.

First off you need to logg into the router by going to the router ip. Usually (192.168.1.1) enter the password. If not changed it should be admin and the user name shouldnt be anything. Now you should be in the index page from here assign a static ip. For example I made mine (24.240.36.6). This wont effect anyother computer on the network. Now go to advanced tab and you should be in filters. Now do the following:

- Disabled SPI
- Disabled Block WAN Request
- Disable Remote Management

Now Turn off DHCP by going to the DHCP tab. After you have disabled DHCP go into (Port Forwarding) there should be a tab. Enter 80~80 and your router ip. If your not sure what your ip is then run MS Dos Promt and type in (ipconfig) it should be something like this (192.168.1.100).
After you find your ip enter the last three digits into the port forwarding. From here you should be set unless your isp has blocked port 80 if they have then port forward 8080. If you change the port other than 80 your address should be something like xxx.xxx.x.xxx:808. If you have charter communications cable service then port 80 is not blocked. To finish it all your address is going to be your static ip for the server. Its not going to be (192.168.1.100). Its going to be what ever you assigned. Now the final step is to go to cjb.net and get a free forwarding. they will turn your xxx.xxx.x.xxx into (yourname.cjb.net). If you want to see an example of mine then go to (pg-hosting.cjb.net) and if you want to test out my ip go to (24.240.36.6). If you have any questions email me.

I test my method on the firmware version: 1.39.1, Jul 19 2001

I don't have a problem fowarding port 80 to another machine.
My problem is that I have a linux apache webserver run virtual server.When I hit my router from outside, only the default site comes up.I can get to any of the virtual site.

Help

I have been having a few problems getting stuff working that require port forwarding through my linksys rounter. From the posts above, I am assuming these four things need to happen before port forwarding will work?:

- DHCP should be off.
- Assigned a static IP to my computer (like 192.168.1.x where x is > 1)
- Disable SPI (what is SPI?)
- Disable Block WAN Request
- Disable Remote Management

...then offcourse forward the right ports to the internal ip...

Am I missing anything here?

Thanks!

OK.. hold up. For those of you that are still having problems with Port Forwarding:

Try this:

- DISABLE all port forwarding
- Enable DMZ setting it as the machine your webserver is on

If this fixes your problems, then the Forward is stuck on the router. (I'm using Firmware 1.42.7)

Re-download the firmware upgrade. This should fix the problem. OR, just leave the port forward off and DMZ enabled.

Linksys also suggests the following down-grades in case the above didn't work:

1.42.6
1.40.2 or
1.39.2

which can be found at ftp.linksys.com

Hope that helps you. It certainly helped me.

peace!

I have tried everything but setting up a DMZ (for work) so I can set up a FTP server. GRC.com's port probe says that everything is still in stealth, so the router is still ignoring all internet requests.

SPI off
Block Wan off

I am using DHCP but the IP of the ftp server is less than .100 so it should be fine.

Any other ideas?

I am unable to use Port Forwarding to SSH into my network from a remote location. Within my LAN I am able to ssh into any machine, get Apache webserver test page up, and Icecast up and running.

But, if I try to SSH to my LAN from an outside location, no luck.

On the Linksys Router
-DHCP is disabled
-SPI is off
-Block LAN Request
-I have on Multicast Pass Thru
-For SSH I have it set to port 22 with TCP/UDP both checked

please help if you have any ideas

thanks

I've been having hoards of problems with my current setup... I can usually successfully connect to a forwarded SSH server and get a shell. Within the shell, i can perform basic fileutil stuff like ls and mv (etc...) but if i run anything with a bit of complexity (such as lynx.. .heh you heard me) the router throws a fit and drops my connection. Everything works fine when connected to the my ISP w/o firewall, and I've tried DMZ and every other option... all firmware revisions I could get my hands on... I guess my solution would be to buy a better router, such as a used Cisco. Anything could be better than this.
