• Port before 1723 Linksys WRT1900AC (VPN)

  I can't establish a VPN tunnel to my desktop using PPTP (built in vpn windows) machine.

  I have a Linksys WRT1900AC, latest firmware (1.1.8.164461)

  I implemented the single port forwarding (this machine has a static ip address below):

  

  I can ping the machine externally, but when I telnet as the machine and the port number (EXTERNAL telnet. IP 1723), his look is no (external).

  I have disabled the windows firewall (although all ports and the gre are defined in the case). I even disabled the firewall of the router to test and helped passtrhough:

  

  I did the research strongly, and the only thing I can think is a NAT behind NAT issue? (Not too well known in network). But I'm not on a DSL modem is a modem cable (Charter company).

  I'm stuck, I know that the VPN tunnel does not work because the port is not listening, but how can I get?

  Thanks in advance,

  Scott

  Yes, the IP address that starts with 192.168.x.x is a private LAN and non routable IP address.

  Your ISP Modem must also be a router with a DHCP server.

  Two Options:

  1. Configure the Modem for Bridge Mode or DMZ
  2. Configure the same port forwarding rule in the modem to the IP address of the WRT1900AC (192.168.44.x). If the modem passes to the WRT1900AC which redirects to the PPTP in Windows 8 Server.

• Port forwarding on Linksys WRT54G

  Hey I have problems with Port Forwarding on my Linksys WRT54G. The port, I need open is 28960. I followed guides and thought I did everything correctly, but his does not work. Here's what I've done so far:

  -J' put a static IP address and took a screenshot of my settings here:
  

  -Here is my page of port forwarding:
  

  -Under the ' security > firewall "tab I unchecked"Block anonymous Internet Requests ".
  -In addition, I tried to adjust the 'DHCP server' for people with reduced mobility
  

  Is there something that I don't forget or do wrong?

  Evreything is fine... Make sure that the DHCP server is activated (do not disable it)...

  The only reason why port forwarding does not work because this port can still report it as "Blocked", this only happens if you have an old firmware on your Linksys router...

  Update the firmware on your router, reset and re - configure from scratch and do port forwarding, see if it works...

  Download the Firmware from here

  Follow these steps to upgrade the firmware of the device: -.
  Open a page in Internet Explorer browser on a computer hard wired to the router...
  In the address bar type - 192.168.1.1... Leave name empty username & password admin lowercase usage...
  Click the 'Administration' tab - then click on the 'Upgrade Firmware' under the tab-here, click on 'Browse' and navigate the .bin firmware file and click on "Upgrade"...
  Wait a few seconds until it shows that "the update is successful," after the upgrade of the firmware, click on "Reboot" and you will be returned to the same page OR it will say 'cannot display the Page.

  Now reset your router:
  Press and hold the button of reset for 30 seconds... Release the reset button... Unplug the power cable from your router, wait 30 seconds and reconnect the power cable... Now re - configure your router...

• ports (vulnerability analysis)

  I ran a scan of vulnerability on a switch 2960 and certain "ports" (I don't even know if it's the right way to call them) showed an opening or which needed to be considered. I really need to know what they are and if I have to keep or have to get rid of them. How do you disable "ports" (I do not speak on the real ports on the switch such as gig1/0/1) on a cisco switch? The ports are 4786 tcp, udp 67, udp 161, 162 udp, udp udp 1975, 2228 and 49688 udp.

  UDP/67 is bootp (used by DHCP). The switch to listening on this port if it is a DHCP itself or is configured to provide the 'ip assistance' service which is used to translate local segment to the end users of programming a unicast packet, which is then transmitted to your DHCP server also.

  UDP 161 and 162 are used by SNMP. Best practice a SNMP limited to SNMP v3 (with authentication and encryption or privacy) and an access list applied to set your authorized SNMP servers.

  The high numbered ports are usually a sign that the device (or a user on it session) is connected to something remotely and it's random port is selected in the > range 1024 (sometimes called 'ephemeral' ports as they come and go a bit random) to use as its source port. As long as the session is open, features "listen" on this port for responses.

  Good link for port number reference.

• HTTPS (port 443) for router RVS4000

  Hi all

  I have two servers - one running MS exchange and other running a crm platform and both must be access via https. On the router - I've linked https to an address ip and router refuses to accept the same port 443 to another ip address binding. I'd appreciate any help I can get to solve this.

  The organization chart is attached.

  

  Hello!

  Unfortunately, it is not possible to have same port simultaneously transmitted to multiple internal IP addresses - imagine even if this setting would be possible, how the router will know who to ask what internal server to transmit from the port where the request has been received the same?

  However, with RVS4000 you can perform the following operations - use TCP 443 for Server1 and say that TCP 4443 for server2.

  Assume that your servers have the following IP address allocation:

  Server1 - 192.168.8.100

  Server2 - 192.168.8.101

  In RVS4000, go to Firewall-> simple Port Forwarding

  Set it up as on the screenshot:

  

  After that you can access from the Internet both servers using the following URL:

  Server1 - https://wan_ip_address

  Server2 - https://wan_ip_address:4443

  I hope this will solve your problem!

• Port 80 and RVS4000

  Hello

  I'm sure this is a stupid question, but I'm stumped.  I have a RVS4000 (firmware 1.3.1.0) as my interface with the internet (I have a static IP address assigned).  I have a linksys WRT120N router directly connected to the RVS4000 for connections without wire - hanging the wireless LAN wireless is a wireless linksys WVC54GCA camera.

  The problem: when I open a browser and hit my static internet address from somewhere else (e.g. home) it goes directly to my setup WVC54GCA page!

  I have no at - enabled port forwarding anything funny I can find.

  (1) what could be the cause?

  (2) the best way should I stop it?  For stop gap I have forwarded port 80 on the RVS4000 traffic to a fake LAN IP.

  Thank you

  How about UPnP? You have UPnP enabled on the RVS4000?

• Linksys 8-port befsr81b and CR-smcd3g cable/dsl router

  Hello

  WAN port on my linksys befsr81b router is connected to comcast cable modem smcd3g-ccr, all the cable modem ports are in auto mode and when I connect to the cable modem it shows 10 Mbps, half-duplex, for this linksys router port is connected to.

  When I connect a PC to the same port on the modem using the same wiring, I get 1000Mbps, full duplex.

  He tells me that the router and modem cable have difficulties at ports the correct port mode. When I change from auto to 100 Mbit/s, two-way, cable modem, the router disconnects and the link light for the modem port shuts.

  I use the version of the firmware 2.45.10, June 3, 2004, on linksys router, which seems to be the latest firmware for befsr81b.

  Can someone tell me what could be wrong with my router or its settings?

  Thank you

  It will not work. The WAN port on the BEFSR81B working on 10Mbps.

• Port Forwarding problem through 2 routers RVS4000 2 subnets

  I modified a building network to be compliant (Visa) PABP where two router and two subnets are required.

  My original CD building network configuration was designed to allow remote access to a server terminal server via the port forwarding on a RVS4000 router. So cables / modems-> xx.xx.xx.xx wan ROUTER lan 192.168.1.1--> subnet 192.168.1.0 with TCP 3389 Port forwarding for 192.168.1.11 (terminal server).

  The new configuration of the network is composed of two routers RVS4000 on two subnets. So the Modem cable-> wan xx.xx.xx.xx ROUTER1 lan 192.168.2.2-> Subnet 192.168.2.0-> DMZ 192.168.2.14 and the second router wan ROUTER2 lan--> subnet 192.168.1.0 192.168.1.1 192.168.2.1.

  ROUTER1 is configured in Bridge mode and ROUTER2 is configured in router mode. Port forwarding on ROUTER1 to port TCP 3389 is 192.168.2.1 (on ROUTER2 wan port). Port forwarding on Router 2 for the TCP 3389 must 192.168.1.11 port (server address terminal server).

  With this new configuration of network I am able to connect to the Terminal Server remotely. No problem with access to the Internet and the 192.168.2.0 subnet from inside the 192.168.1.0 subnet.

  So I think my problem is through two RVS4000 routers port forwarding. Any help on this problem will be appreciated.

  Thank you.

  1. can you access the terminal server server from inside the subnet 192.168.2.0/24 using the IP WAN to Router 2, which is access 192.168.2.1:3389 from inside 192.168.2.0/24.

  2. turn on Router 2 router in Bridge mode. Try again. My guess is that this will make the work of transfer. I think that port forwarding is linked to the NAT/gateway mode. No NAT no transfer. Is not logical to use the transfer when you are able to access the IP directly without NAT. Of course, the web interface does not allow you to forward a port located outside the LAN subnet...

  3. are you sure that you can access internet through Router 2 in router mode on the LAN subnet router 2? Usually in the NAT their own LAN subnet routers only bridge mode but not others. If the RVS4000 not NAT a different subnet that would be good to know.

• RVS4000, port forwarding - with - IP-based ACL

  G ' Day!

  I want to know if it is possible to enable port forwarding and paste an IP based ACL on the attacker.

  Scenario:

  I replaced my gateway linux with a RVS4000 and reinstalled my linux machine as a file server with sshd running (now residing on my network behind the RVS4000).

  I have forwarded port 22 on the RVS4000 on my linux server - it works as expected. Now I want to restrict which IP addresses which may connect to port 22, that I can't go to work.

  After I forward port 22 to the linux server I can't control it with IP based ACL. Even if I deny all traffic to port 22, it will leave borrowing at the server linux as long as the port is active.

  I am doing something wrong or if this isn't just intended to work the way I want?

  acl based port will not work with the port forwarding on the device. Once you transfer the port are all allowede to enter this port. the acl will not take effect. I think that what you want to do the port binding is not a feature of this device.

• Linksys E2000 to into acccess point/switch helps.

  Okay so here's the deal, we got At & T Modem/Router upstairs, and then we had a long cable ethernet connecting here in the basement. The problem is that this allows only a connection to the local network at the same time (a problem for LAN parties and others). I do have a Linksys E2000 router however and I want to be able to use it as a switch access point.
  I'm sure this is possible, but I forgot all the steps to do so.
  The att modem/router is running on 192.168.1.254 and my Linksys that is directly connected is on 192.168.1.1, so I have another address in this field.
  What I need to change my Linksys settings now, or do I have to change the settings for at & t?
  Basic steps would be appreciated, but I am familiar with the concepts of normal network, so you mustn't it level by the low that much.
  Also I will use this for Xbox Live at points so will I need to re - open all the ports on my Linksys, or at least put the DHCP to static IP Xbox to keep my NAT good?

  Thank you

• Can I connect printer to the usb port on the cable Modem CM100

  Hello

  This may seem like a stupid question, but here goes... I know that the usb port on my Linksys Cisco CM100 cable modem is an optional way to connect the modem to the computer. I wonder if I can use the usb port to connect my HP 1020 laser printer instead.

  The printer is not a network printer, and so I know that it may not work, but I have seen a few cases where a virtual port and install it as a local printer got to work.

  If I can connect the printer to the modem, and then he would give me a way to print from my laptop in the other room.  My printer is just beside my modem configuration and the router. I have a Linksys router WGR614 wireless who sees the devices on my network share, so I think he could see the printer connected to the modem (?)

  I couldn't find the answer to this anywhere. I didn't damage my equipment by blindly try this without knowing a little something. (I assume that the heart of my question is, on the CM100 usb port can be used for any usb device)?

  (I have Windows 7 64-bit operating system, in case you need to know).

  Thanks to anyone who can answer.

  A standard print server will allow you to connect a USB printer to your network. There are models wired and wireless depending on how you want to connect to the network.

• Advanced Port forwarding rules

  I bought a WRT1900AC router and changed my old router Dlink DIR - 905L.

  There is a function in Dlink to set a unique public port in the router to redirect a private IP LAN and LAN if necessary internal address port. This is called: "Advanced por rules of transfer".

  In this function I defined a rule like this (real case):

  Name: CCTV

  IP address: 192.168.0.120

  Public Port: 80--> 80

  Private port: 80--> 80

  Tye of traffic: all

  Question: Where can I find this function in the WRT1900AC?

  Appreciate your help, my CCTV is not managed.

  Hi HappyLefty. That's how we have implemented simple Port Forwarding on Linksys routers. Will we know what you want to accomplish with the WRT1900AC? We would like to have a better understanding of your challenge with our camera so we can help you accordingly.

• Linksys E1200 with Verizon Fios Actiontec

  Hello. I bought the E1200 Linksys because it is Wireless N and the guest account. Please help me configure my new router Linksys E1200 to use for Wireless N instead of my Verizon Fios provided Actiontec (model place M4124-WR), which is only G wireless, and so that I can use the guest account. I have an ethernet cable from one of the 4 ethernet ports on the E1200 to one of the 4 ports LAN on the Actiontec. I have the wireless off on the Actiontec and have the E1200 defined as 192.168.1.200.

  My Wireless N signal seems to work very well in the E1200 and I managed to activate the account invited on the E1200 and 'connect' on my iPhone 4, but then when I open Safari I can't connect to the internet.

  Thanks for trying to help, but I had worked after a phone call with a cisco/linksys support person. I had to make the following changes:

  The default gateway on Linksys E1200 after a hard reset is 192.168.1.1... I had to change the default gateway on Linksys E1200 to 192.168.5.1

  Connected to port LAN 1 of the Actiontec to the Internet on the Linksys E1200 port.

  Connected to the computer to port LAN 1 Linksys E1200.

  Off the Linksys E1200 and the modem (Actiontec) for 30 seconds. Then, back on the Actiontec until what the internet light turned on, and then turned back on Linksys E1200.

  Made sure that the wireless security page has been set to WPA2/WPA Mixed Mode because apparently the acct comments not use WPA WPA2.

• On WRT54G port forwarding

  Hello!

  I need assistance with portforwarding on my WRT54G. Any port range, I can't make it work.

  I'm sitting at a Mac, cable connected to the Linksys. I had connection-fiberglass.
  Where to start? I think I've tried everything, but somewhere seems to be a small option unchecked.

  I opened the port on the Linksys, check the Enable box.
  The computer has a static IP address to the router.
  I unchecked her block anonymous Internet requests.
  I have disabled the firewall on my computer.
  I have reset the router and everywhere.
  I tried DMZ.
  I have updated the firmware of the router.

  I called my provider and asked if they accidentally blocked some ports. They said that they do not have, but I was behind a firewall, which should not cause this problem. They put me "on a public IP address" (if I remember correctly, what the guy said, tell me nothing) just in case.

  Feels like I'm bored of what is obvious, but what? I'm grateful for any help.

  Best regards, P.

  If the internet IP address of your router is 10.60.0.1 then there is basically nothing you can do. Your ISP is running another NAT router. This means that you must implement two expeditions of port: one on the ISP NAT router and one on yours. Obviously, your ISP won't... You can ask only your ISP to assign you a public IP...

• Help with the VLAN and RVS4000

  I am trying to Setup VLAN on a RVS4000 to share our Internet connection with another office but do not allow access to our network of the other network. We have a BEFSX41 connected to Internet and also connected to our other site via a virtual private network to another BEFSX41. Port 1 on the BEFSX41 connects to Port 1 on an EZXS88W switch.

  The other company has provided the RVS4000 and also provides a WRT54GS router. I want to connect 2 ports on the BEFSX41 to Port 1 on the RVS4000 and 2 ports on the RVS4000 to track 1 on the WRT54GS.

  Port 1 on the RVS4000 is member of the default VLAN1 and Port 2 will be a member of VLAN2.

  Our IP network is 192.168.20.0/24

  BEFSX41 is 192.168.20.1

  The DHCP service is disabled

  The RVS4000 has a static IP address of 192.168.20.254 and is configured as a router

  DHCP is also disabled

  The wireless network is as follows:

  IP network is 192.168.21.0/24

  The address IP of WRT54GS is 192.168.21.254 and is static and also configured as a router.

  I don't know how to actually Setup the VLAN from here and the instructions are not useful. My questions are:

  1 port 1 on the RVS4000 must be safe, with label or Untagged?

  2 If the interval routing disabled?

  3. If so, how do I route between the RVS4000 and WRIGHT so the two networks have access to the Internet, but not to other networks?

  The befsx41 should be one that is connected to the internet so that your final point so that the vpn tunnel work. The wan port on the wrt54g must be connected to the lan of the befsx41 port.

  If your server is located behind the befsx41, you should be able to port forwarding. If your server is located behind the wrt54g you may experience the problem with the redirect because you need to forward ports on both routers and according to me, there are some applications that do not work on double NAT.

  If you want to have access to the internet on both VLAN of the rvs4000, it should work as a router so its internet port must be connected to the port the befsx41 lan.
