Linksys Wireless Router :: Port Forwarding Stops Working WRT400N?
Jan 16, 2010
Having a problem with port forwarding on their WRT400N? I'm forwarding one service (https) and this stops working if it's not accessed after a 10 days or so. The only way to get it to work again is to reboot the router. I’m running the “latest" firmware, which is an oxymoron considering it's been over 12 MONTHS since Linksys updated the code... Which is appalling considering this appears to be their flagship wireless N router.
The Port 80 port fowarding stops functioning after a few hours and requires the router to be rebooted to start forwarding again. The firmeware is the latest 1.0.04 Build 7. I require it to operate reliably for many days without intervention. I assume that it is a port forwarding problem because I can access the IP on my network from within my network even when I can't access it from outside my network. I am using the correct IP addresses as it sometimes works OK. A characteristic is that when I can't access the page it loads as completely blank white with no error message.
I am using a RV110W with the latest firmware 1.0.1.6 I have some port forwarding configured, which normally work. But sometimes, all port forwarding stop working. Everything else continues working normally, just all port forwarding don't work any more. I tried disabling the port forwarding and enabling them again, this doesn't work. Also disabling the firewall completely does not work. You have to reboot the router, then everything works fine again. When I make a portscan from outside with a "fresh" started router, the forwarded ports are open. When the error occurs and I make a portscan from outside, all ports that should be open (and have been open before) are closed.
This happens intermittantly. This results in most connections (but not all) being dropped. I will be unable to connect to web servers. My connection to videogame servers will drop. However, AIM will stay connected. These were done simultaneously. The same thing happens with my Cisco AE1200 and a D-Link 802.11g adapter I have. Disconnecting my adapter and reconnecting it solves the problem. I have tried doing a factory reset on the router and installing the latest firmware. It seems to happen more frequently when I am doing a lot of throughput (downloading a game on Steam, for instance) but other times it will happen when all I am doing is playing a game (like Tribes Ascend) which uses very little data. This is extremely frustrating. When I pay more than $150 for a piece of networking equipment, I expect it to last more than 3 years.
The wireless drops specifically from my laptop constantly at random times. When the wireless drops in order for me to be able to reconnect i have to restart the router itself. There are also random times where the Wi-Fi stops broadcasting altogether. I have a computer connected via Ethernet and it does not lose connection during these times. All the computers are running Windows 7 and the Router is up to date on firmware.
I have a RV042 router on a single WAN and an internal LAN. I have configured port forwarding as follows: HTTP[TCP/80~80]->10.0.0.6HTTPS[TCP/443~443]->10.0.0.6IMAP[TCP/143~143]->10.0.0.5IMAP SSL[TCP/993~993]->10.0.0.5SMTP SSL[TCP/587~587]->10.0.0.5
Everything works just fine when I have the firewall DISABLED. However, when I enable it the behaviour is erratic. 1 out of 10 attempts to connect to ANY port forwarded works. Almost all attempts time out. Notice that this happens even if using only the default firewall rules (which should be bypassed by the port forwarding as I read in other posts).
My second try was to create firewall rules manually, overriding the default ones. I tried adding rules from source WAN1 (where my connection is) to ANY and to SINGLE IP's on every port. Nothing seems to work.
I don't know what I'm doing wrong, this is really bugging me. I had to turn the firewall off so we can access our servers from outside the office. This shouldn't have to be done.
Just found out that my firewall is getting LOTS and LOTS of Blocked - SYN Flood entries. I think this is why we are having trouble with the firewall. Could this be the problem? I have no idea where all these SYN packets are coming from since they appear with spoofed IPs or come from different bots all over.
I upgraded to a 6500 from a e4200. I use ports 81-84 on test web servers set to static Ip,s when I open the ports nothing can get through from the outside. I can hit the pages internally on those ports and IP's but not from my external ip to those ports. When I set my old router everything is fine.
I set up port forwarding on my router. When I go to canyouseeme.org and put in my public IP address (I can ping the IP address with no issues) and the port that I'm forwarding it says it can't hit the port.
I've read over the FAQ and followed the normal instructions for port forwarding, but can't seem to get it to work with this particular router, E2500. I have tried both the single port forwarding and the multi port range forwarding, and neither works. I've tried an older WRT54G router and port forwarding works fine on it, so I know it's not my ISP.
I currently have an E1200. I can port forward single ports, but when I attempt to forward a range of ports it doesn't work and there is no error in the log.
Specifically I am port forwarding RTP ports (10000 - 20000). I am aware of the security risks, please do not preach.
I am trying to run a server for minecraft, which some of you may know primarily uses Port 25565. I have tried everything that I've seen suggested. I have a Linksys WRT54GS router that I have my 2 xboxes, playstation 3, pc, and wii connected to. Now, I don't use any of these components at the same time. I had an issue with my xbox and the game "Black Ops", where my NAT type was strict, but a microsoft support technician walked me through port forwarding for the xbox, and it worked. My NAT type was displayed as "open" now. This is not the case with Port 25565 however, as even though I've port forwarded 25565 to my static IP i set up for my PC (which is my server PC), Port checking sites such as "Yougetsignal" and a couple of others are still showing no connection for the current external IP and Port 25565.
I went through ipconfig in windows "cmd" and made sure I had all the ip's and subnets and dns' and whatnot correctly entered in my routers configuration page. I went into Windows firewall and put new rules for port 25565 into incoming rules. None of this seems to work. I even shut off the firewall completely (temporarily, mind you), just to eliminate that possibility, to no avail. Still getting negative responses from these sites. I am able to log into my server myself, using "localhost" as the address, but none of my minecraft buddies can get on my server. I've also tried to use Hamachi to set up a server, which doesn't need ports to be forwarded, but although they can join my hamachi network, they can't join the server. Obviously there is more of a problem than just not being able to open ports, and I am at a loss.
Also, I am aware that my external IP, given by my ISP, will change with every disconnect and reconnect of my signal. I got my current IP address during this time and gave that to my buddies so they could join the non-hamachi network. For the Hamachi server I edited my Hamachi network IP into my server software's properties file, where as it would be left blank for my non-hamachi server.
I've had the WRT400N for about a year and a half now and just last night it stopped sending out data when connected to my cable modem. I've tried connecting the modem directly to my Mac and it works just fine (that's how I'm sending this message now). But when the modem is connected to the router, I get no data. It connects to both the 5 Ghz and 2.4 Ghz networks, but it refuses to send data through the pipe. I've tried power cycling both the modem and the router to no avail.
I have some hardware on my internal network which I want to send udp packets. I can connect using telnet to it prooving that TCP and port forward works but when I try to send a UDP packet externally it fails.I can however send the same packet internally and port forwarding works fine.My router is Linksys by Cisco WAG320n.
I'm trying to open some ports for my webserver, I've configured the static IP and forwarded port 80 to my server's IP and I checked the port on canyouseeme.org and it says it's closed. I've tried multiple ports (21, 22, 7878 whatever) and all do the same thing.
So my next step was to try DMZ on the server's IP .. still no happiness .. ports stay closed. I checked this on multiple computers and it still won't open any ports for any machines on my network.
Updated to the latest firmware .. didn't make a difference. My ISP doesn't block any ports (didn't have any issues on my old router.
I have got a Linksys @ Home HG200 V2 G Gateway. I am trying to setup port fowarding but its not working. I have gone onto the routers port forwarding setup page filled it out but the port is still closed.
A few days ago, my Linksys E3200 router stopped working suddenly for no reason. The SSID was still broadcasted for a few days, but no internet connection. Today the SSID does not broadcast at all and I seemingly have no access to it.I tried power cycling it.I tried reconfiguring it via the CD included in the box.I tried solving it with the wireless tools in Windows.
I just bought the E4200 routher at best buy a few weeks ago. I got it all setup how I want it. Its been working fine then about a day ago it started to stop working at random. All internet just stops working. Wired and Wifi. I have to either wait for it to work again or restart the router.
I have a Cisco Linksys E1000 wireless router. It has been working perfectly for the last few months until yesterday when I noticed none of my wireless devices could connect. The SSID was still being broadcast and my computers that were connected through an ethernet cable were still able to access the internet fine. Eventually I pressed the red reset button on the back of the router, which reset my router name, password, etc. I set everything back up and was able to connect again. Several hours later the wireless stopped working again. When I launched the Cisco Connect software I was prompted to update some software (possibly the router firmware) so I did that. After that I was able to connect to wireless again. This morning I woke up and wireless was not working again. This time I changed the password for the router and then I was able to connect to wireless again. I tried to change the router password back to the original password and I couldn't connect anymore. When I changed the router password back to the new password I could connect again.
I'm having a bit of trouble with my e4200, It keeps on "dropping" connection, and by dropping I mean it constantly around 3-5 minutes the internet stops working with all my computers, it's connected by wifi with 2 PC's, and 1 PC is wired with an ethernet cable, and I also have 2 mobile devices connected at it. The internet would start working again within 30s, to 1m, but that it drops soon.Methods I've done to fix it:
-Updated firmware to the latest one -Set the MTU to 1400 -Reset it, (30 second press) -Rebooted, (Cooled down, doesn't really run hot just a little warm) -Restored to factore defaults
Right now I have my computer (iMac early 2012 summer purchase) plugged directly into the wall via ethernet cable for internet access. I have only begun doing this in the past week because my E1200 wireless router has stopped working properly. I have reinstalled and reset to factory settings and set up with Cisco Connect and setup manually over the past week troubleshooting every possible way I have ever known how. My internet, obviously, is working. And when I set up the wireless network it connects properly and obtains an IP address and the lights on the back of the unit light up correspondingly and correct. But I cannot connect to the internet via the router, wirelessly or plugged directly into it. Yet when I take the internet cable and plug it straight into my computer it works.Mainly just need to know if this can be fixed or if I need to go return this unit and get a replacement. The router was purchased two months ago and has not had any issues since I first set it up until a couple of weeks ago and my phone is using up all of my cellular data plan without being connected to my wi-fi...
None of the port forwarding settings are working at all on my router. I have just a couple very simple settings. One of them is just an IP camera. I input the name, the TCP port, the computer (IP address) and that's it. This works just fine with my other Netgear router, but with this router, NADA. The router has the latest version of the firmware applied. Just applied it. Hardware version B. Firmware version: 2.10NA. If so, then I really need my money back since it is a main function of a router and it should work. Can't return it now, since I bought it several months ago. Never knew port forwarding didn't work because I never needed it until now.
I've tried all sorts of settings, and I'm still holding out that its a setting possibly, but I have a E3500 and devices on both 5Ghz and 2.4Ghz... Most of them, probably when idle, seem to stop working over WIfi. They still have decent connection, but every internet related request just times out. Disable and reinable the wifi and it works great again.
Could this be defective wifi radios? or could it really be interference? I have it happening on multiple devices. Also, I'm not far away from the router when it occurs, and when I reconnect, it seems to work just fine for a while. Basically the big problem is on the cell phones and tablets because I'll miss notifications... I'll turn off the wifi and turn it back on when I use the device next, then a flood of notifications will come in. Again, it's not just a phone thing, tablets and laptops have the same problem, that's just the main reason I want it fixed.
RV215W router port forwarding not working.Port forwarding works for a short period of time, then stops working. Reboot router, works again for short period of time, then stops again.
I have updated firmware to latest. I had seen other similar bugs posted for 220 and I think 180, not sure if this router has similar bugs and waiting for fix release to firmware.I had recently purchased two, one deployed, will hold off on other now because of issues, and may have to move to different unit if a resolution not found this week.
I am finding it impossible to set up port forwarding. No matter what I do I remain completely stealthed when I do a port probe via [URL]... The only way I seem to be able to open a port is if I enable remote management. When I do that, whatever port I specifiy as the remote management port is then fully open. Obviously, I can't leave a port exposed like this and, anyway, I need to open multiple ports for my purposes.
I use modem and router to connect to the internet.When I connect my PC directly to modem port forwarding is working.When I connect my PC through my router the port is closed. I followed instruction for port forwarding.
I'm trying to port forward with the Linksys BEFW11S4, I've followed all the instruction from support website. I went to the Application & Gaming then Port Range Forwarding. I changed the settings so I can access this IP remotely. When I try to log into this IP from a different network it wont let me.
I am trying to port forward my Linksys e4200 router v 1.0.04. However, it is not successful for when ever I check if the ports are open they fail they test.
I am sure that I am doing the actual port forwarding correctly (I hope), but something is refraining the ports from being open.
I am trying to install and use EchoLink on my pc's and they require port forwarding for 5198-5200 but I'm having trouble with theTo IP Address" as I don't know what # to use. It says I can't use 192.168.1.1 since it's the same as the LAN IP address so what do I use? I am trying to follow the instructions on [URL] If I leave it just as 192.168.1. it won't accept it and if I use any other number, it accepts it but I still can't get through.
My first issue with this device is when I try to untick NAT to disable it I lose my internet connection. This also disables access to router's address 192.168.1.1 forcing me to reset the device and set it up all over again. Why is this happening? I tried this at least five times with the same result. Second question I have is if the DHCP reservation is the right option if I want to forward ports for certain applications like Vuze? When the DHCP reservation window opens I see all my wireless devices in the list (laptop, phone) but not the main computer which is connected through ethernet port. But that is yet another problem.
I've got a cable modem, connection is set to Automatic DHCP and I all want is to disable all firewalls, NAT and other unnecessary protection that's slowing my internet speed, set up MAC address filtering, port forwarding and close this terrible software so I never have to see it or think about it ever again.
I just bought a WRT120N wireless router, and have run into some strange problems with port forwarding. I have a two router setup, because my ISP have set it up so i can only use my router from them to get my connection, and then i just have that one connected to my WRT120N. So my setup looks like the following:
The problem is that ONLY the three first ports works. I have forwarded them in the exact same manner, give it a name, put in the same external and internal port, and enable the port forwarding, but according ot can you seeme.org, only 4667, 6112, and 4669 can be seen, the rest is not responding. I even tried to enable port 21, which is a default setting in the router, but it will just not work.I have of course tried to reboot both router and PC, upgraded the routers firmware, but no luck.
I'm a happy user of the E4200 for a few weeks now, and all in all it's a very robust and useful router.Within my network I have a webserver running using both HTTP (TCP 80) and HTTPS (TCP 443). I want to make this webserver available to the internet and so I configure port forwarding to forward port TCP 80 and TCP 443 to my internal webserver. As soon as I now apply these settings, I loose connection to the webinterface of the E4200 and get connected to my internal webserver. I would expect the router would only forward connections coming in through the external interface of the router, however this is apparently not the case (or at least not in my setup). So I tried setting up remote management on a different port to at least allow me to remotely manage the router, but this does not work from my internal network.
Right now, I'm assuming I'm doing something wrong, or have miss-configured something. Is it possible to switch the webadmin port to a different port (like 8080 and 8443)?

I recently got a e2500 router and set up the port forwarding for my ps3. But then i go to check the ports to see if they are open and they all stay closed.I have no clue whats wrong as I have entered the port forwarding info correctly as I got guideline from portforward.com but still no luck
