Cisco Security :: 7606 - Unknown Open TCP Ports On Router
Oct 19, 2011
Any know how to close these open ports on my Cisco 7606 router? Any know what these TCP ports are used for?
:
49 - Not sure what this one is other than what IANA reports about TCP port 49

I'm sure I could add an ACL to block communications to my router based on this ports but would rather figure out how to close 'em so this already overloaded router doesn't have additional processing.
My reports say that my listen ports are blocked even though I removed my router already. I've enabled these ports in Windows firewall already. Why are they still blocked?
We currently have the XG1 through XG4 ports on our SG500X switch setup in a LAG with the Cisco 10G-FiberOptics. Everything is working fine,however in the web UI under Port Management->Port Settings the "Port Speed" is listed as Unknown. All other ports report the speed correctly. We have 2 SG500X switches configured this way and both are reporting the same Uknown speed.
Firmware Version (Active Image): 1.2.7.76 Firmware Version (Non-active): 1.2.0.97
by saying "open ports" in a router or PC or other Network System what we mean basically? what is opposite terminology, "closed ports"?-used or unused-sensitive-vulnerable or non vulnerable to attacks-exploited easily and when so may attacked and have much bad/serious consequences/results
I have been trying to host games for some time now with no luck. I believe it is because i cannot open the proper ports. I own a Linksys BFSR41 Ver. 4 router. I have been trying to open ports, testing them on a port checker website and they are always listed as closed. I have followed the guide on portforward.com perfectly with no luck.I have disabled Block Anonymous Internet Requests.I have disabled my Windows firewall, and AVS. Still cannot open ports.I have also updated to the latest firmware. I am using Win-7 x64.
I am considered as a novice when it comes to networking, modems/routers etc.I have a Belkin Modem/Router, I need ports TCP 80, 2300 and UDP 2310 I think to be forwarded so I can play a certain game online (Age of Empires 3). I have tried DMZ mode for my pc and I can play the game online but only with DMZ enabled. Just some extra info.Belkin Modem/Router model : F5D7634-4A-H v2 (on the device)F5D7634-4-H v2 (01) (on the online settings (192.168.2.1))It has the latest firmware as I have clicked on the firmware update and it says "There is no new firmware update available for this Router!"
cant open the ports 2300 -2400 (udp, tcp)on router. What I do isthe following.
1. Open ports on router in port forwarding.
2. Add the triggers as well in APPLICATION RULES with the ports. Triggers are 47624 and 6073.
3. Try both Dis and Enable UPNP. Even try the DMZ enabled settings.
4. Disabling firewalls on Laptop and router. Try both ways on DMZ's(enable and disable) settings on router. Check everything.
Still when I check on websites about the ports and they are shown closed (NOT STEALTH). Router uses a firmware 4.0. I have a windows 7 64 bit system. I use wireless.
Note: All the steps are performed in a combinations manner to see if there is any possibility of opening ports.
I have been having trouble forwarding ports for different softwares and servers. I just upgraded my internet and my ISP sent me a new modem/router all in one. I am using a wired setup to my desktop. The router I am using is Sagem FAST 1704.
My ISP told me that they only give support for game consoles, the dumbest thing I ever heard since I don't pay for their internet so I can play games. Cannot forward a simple port. Port 100 in specific.
When I forward ports, I am certain that I'm typing in the right Ip address digit because I checked ipconfig. Then I check the 'canyouseeme' website and it tells me that the port is not open on my ip address. I have tried other means of checking to see if the port is open but they all tell me the port is closed. Once in awhile the port will be open but most of the time it isn't.
I plug in my older modems and it doesn't make a difference when I re-set up the port forwarding to the new IP so I guess it isn't a problem with the modem or router. I changed all my ethernet and phone cords and filters as well. My isp told me that they do not block ports.
My isp is Windstream. I cannot set up a static IP in network connections because when I do the internet doesn't work at all even if I set the exact same settings that are currently set. This happens with both modems I have. I do not use two devices at one time just the modem or the modem/router, there are no other computers connected and filters are on all phones/satellites. I am using Windows XP, not sure what other info you will need.
My isp keeps telling me they do not support setting up vpn's. I do not need support for that I just want to open a port. lol the next thing they told me is, you guessed it, "We do not support setting up VPN please contact your work IT........" which doesn't exist. I spoke to three of them and they all said the same thing, except one told me they were going to open ALL ports for me. That didn't happen.
I just want to open up a few ports for Age of Empires 3 but no matter what I do the ports still stay closed.I have a Belkin F6D4630-4 v2 modem/router (firmware updated to 2.00.25) and I use https:[url].... to check my ports.
I've forwarded the ports 2300-2310 in my router (both TCP and UDP) using the 'virtual servers' thing.
I've disabled windows firewall.
I've disabled my AVG antivirus.
I've disabled and enabled this thing to see if it would make a difference: "UPNP Enabling:
Allows you to turn the UPNP feature of the Router on or off. If you use applications that support UPnP, enabling UPnP will allow these applications to automatically configure the router." When I probe the ports from 2280 to 2330 using the Gibson research website, the ports I forwarded (2300-2310) say 'closed' and the others say 'stealth'. Why do they say CLOSED and not OPEN? There shouldn't be anything blocking those ports.
When I probe the ports from 2280 to 2330 with windows firewall ON, all of them say 'stealth', even though I've added those ports to the windows firewall exceptions.I just want those ports to say "OPEN" so I can join all games on Age of Empires 3 instead of coming up with the message "Failed to join game".
I tried forwarding ports 80, 443, 7001, 8888, 9901, and 9911 on my Linksys E1000 router but whenever I check my ports always come back as closed. This happens even why I try to enable DMZ.
The last few weeks I've been having problems with my 360 Slim. Sometimes it boots up just fine, other times it wont connect to XBL at all. Some days I have a open NAT, other days I have a moderate NAT.
I have followed the steps on the portforward website. I make a static IP and all that good stuff. I open the ports, using the IP address the Portforward static IP program gives me. After that...My computer stops working. It fails to connect me to any websites at all.I'm running a Linksys ea3500 router.
I am using remote management to attempt to open port 8889 on my Linksys WRT54G router. I have successfully opened ports 22 and 80 with no problem. Additionally, I can close and reopen these ports without having to physically reset the router. However, if I try to open any other port (I have tried various ports: 23, 100, 8888, 8889, and several others) this port will not open. The ISP this router is connected to is Comcast and according to this site URL port 8889 isn't among the ports that Comcast blocks. I have tried everything I can think of to resolve this issue (short of manually resetting the router or restoring the default settings).
I am running a Linksys Wireless G 2.4 GHz Broadband Router Model WRT54G. I am unable to open any ports. I upgraded to the latest firmware yesterday but still am unable to open any ports. I even turned off my Symantec Internet Security Suite Firewall but still am unable to open any ports.
im moving over to VDSL.But now i cant open any ports on the E4200 no mather what i do.It worked with the previous modem, but now i cant open anything. all the ports seems to be closes, 80, 21 etc, and the ports i manually forrward.The previous modem was a ZyXEL P-2602HWT-F3, and the new one is a ZyXEL P-2812HNU-F3.If i connect directly into the ZyXEL P-2812HNU-F3, every ports seems to be open, port 80 is open, port 21 is open, but not on the E4200, and yes, i have tried open the FTP ports.I have tried the 30/30/30 reset on the E4200.
How do I go about opening specific ports on an E4200?I'm having disconnect issues with a particular game, and the Customer Service drone thinks the ports required for the game aren't open. Nevermind the fact that it's worked fine for 6 months now, and the problem only started a few days ago.I figured I'd humor the idiot and open the ports, but all I can find is information on forwarding, not making sure the ports are open
I need to open four ports and have no idea how. My web host thought that my ISP was blocking them; the ISP says they are not and that it is teh router. I don't have pjone support anymore (WRT54G is old) so could not be walked through it by a tech support person.
I have been using Linksys routers for quite some time now, and recently made a big upgrade from the WRT54G to the E3000. I am familiar with the 192.168.1.1 interface and its functionality. However, I recently noticed a problem: when I set a port to forward traffic to any IP address on my network and then check whether or not it is actually open (url...), I am told that the port is still closed. More interestingly still, the first port that I forwarded when I first got the router is listed as open, but the other half dozen or so are still considered closed. I have been trying to set up a file transfer protocol (FTP) server, but can't even get traffic to forward from port 21! I even tried using the pre-configured FTP drop down on the Applications & Gaming tab, but to no avail. Has anyone had similar issues, or perhaps an idea as to why only one port is forwarded when I have followed the same steps that I have been using for years?
I tried to get in touch with Technical Support about this issue, but was told that I needed to purchase a $30 subscription in order to qualify for assistance. I don't think that I should have to pay $30 to know why the same steps work with some ports but not with others.
I've DMZ'd my computer using the the E1200's Web Browser Config screen (192.168.1.1) yet when I try to test the ports not a single one is open.
I've used this test to see if they were open: [URL]
And almost none of them were. Is there any issue that could be causing this?
Also when I try to open a single port the site says it times out. Opening single ports didn't work either. I've also tried to DMZ via the IP and the MAC address of my PC and still no luck.
open specific ports on 1941w Integrated Services Router.This specific router is a wireless VPN router that has a wired module and a wireless module and VPN so I'm getting 3 subnets on my network - 192.168.1.. for the wired connections, 10.100.1.... for wireless LAN connections and 10.100.2... for VPN remote connections.I know that by default all connected computers can access my Linux server data through telnet so the telnet port is open by default, the problem is that I have some other software licensing system on my Linux box that needs to be accessed through port 27000 and most of my users are using wireless connections and can't access that license because post 27000 is closed.what is the comand to open this post or any other port that I need to be open on the wired module, wireless module and VPN or at least poit me to somewhere where I can find all the commands that I can use for this router?
I have D-Link's DSL-2730U modem/router. I've enabled the router's firewall and disabled TR-069 (putting in some dummy ACS URL and login credentials as well). However port scans show 30005 as open. I believe this is used by the TR-069 client. How do I definitively filter this port?
I have a Cisco 877 connected to a VSAT modem, and I can't open ports outside, I dont know why?The Cisco 877 Fa0 port is connected to the VSAT modem at VLAN9, and the rerst of ports are connected to the local lan network at Vlan2. I can enter to Internet, but I can't open port outside. ADSL over pots is not used here.I need to open port 81 for ip address 192.168.1.130 and I dont know why this isn't working. Also if I do: sh ip nat translations I see this:
sh ip nat translations cisco877#sh ip nat translations Pro Inside global Inside local Outside local Outside global tcp 172.30.xx.122:81 192.168.1.130:81 --- --- udp 172.30.xx.122:81 192.168.1.130:81 --- ---
How can I allow all ports to be open? I don't really want my 1811 to block any traffic. I tried the command access-list 1 permit any which allows me to surf the internet, but when I check my web server, and port 3389 (Remote desktop) on yougetsignal.com it says those ports are blocked.
I need to open ports 25, 993, 995, 443 and 465 to setup MS-Exchange. I don't have an inhouse IT guy and this seems pretty straight-forward in theory but I can't figure it out I need to open ports 25, 993, 995, 443 and 465 to setup MS-Exchange.
I'm setting up a second exchange 2010 server at a DR location and have been experiencing some problems. The two sites are connected via a pair of ASA5510's using the point to point VPN. I want to rules out any possible VPN issues that may be blocking ports and wanted to see if there is an easy way to do this and simply allow all traffic without any restrictions between the two ASAs. I've attached the scrubbed configs here...Ewing is the primary site and DBSi is the DR site.
