Homehub 3 - port translation / redirection

I have a network problem which I am hoping someone may be able to assist with: I am planning to deploy a number of wifi range extenders in my home network. The extenders, once configured, can be administered locally (i.e. from within the LAN environment) via an HTTP / port 80 web browser. I need to administer these devices from the internet side of the router. By implementing a rule on the port forwarding screen I am able to route all inbound traffic on port 80 to a specific range extender in the LAN. This is where my problem begins as the router can apparently only route traffic to one such device via port forwarding (I need to access several such devices). The range extenders themselves can only listen on port 80. A possible option would be to use port redirection within the router but I cannot find any port translation / redirection facilities in the Homehub 3  router to enable this for multiple devices. For example, I could target port 8000 (inbound) which might then be converted to a local address on port 80, so 2.120.45.247:8000 would be translated at the router to 192.168.1.5:80. Further to this I could then target 2.120.45.247:8001 - this would be translated at the router to 192.168.1.6:80. If what I am proposing is not possible please could anyone advise any alternative method for achieving my requirement?

Its more likely to be a coding issue within the web site. You need to check that any internal references are relative to the actual page, and do not use the absolute address.
I had a similar issue when I ran my website on port 8100. Some of the images would not display because the were given full web adresses, and not coded relative to the actual page they were needed on.
I would imagine that your form data is being returned with a port 80 header, and would not leave your server.
I am using a normal ADSL connection, and in the end, I had to move the web server to the normal port 80, as it was too much hassle to deal with the coding. Also I use Wireshark to keep a random check on traffic, and having to alter it to decode http on port 8100, was too much bother.
This is only a guess at what may be happening in your case.
Is it not possible to run your website on port 80?

  • LRT214 Accessing Web Services with Port Forwarding & Port Translation

    Good afternoon to all,
    Purchased the LRT214 yesterday afternoon and it was a breeze to configure the internet settings and get back online. But after the initial configuration, I ran into some trouble getting the router to do port translation together with port forwarding.
    The port forwarding setup is straighforward and works perfectly, the same cannot be said for the port translation which does not seem to work. I programmed the following,
    1) external port 88 forwarded to internal port 80 for 192.169.1.12
    2) external port 89 forwarded to internal port 80 for 192.169.1.13
    Can someone point me in the correct direction to achieve the above?
    Router Model : LRT214
    Firmware Revision : 1.0.2.06
    Working Mode : Gateway

    Port Address Translation => Service Management
    Add two Services for the port translations and then add the translations to the list. Let us know if you get any errors.

  • Port Forwarding with Port Translation RV042, RV016, RV082

    This is a feature request for the Linksys RV series Routers.  Currently, it appears that the Cisco/Linksys RV042, RV082, and RV016 only support port forwarding and 1-to-1 Nat.  One item that I find very helpful with customers is port forwarding with port translation.  I am requesting that this feature be included with a future firmware relase for these RV series routers.
    Here is an example of the request.
    Take an incoming service request on a TCP or UDP destination port and forward it to an internal IP on a different TCP or UDP port.  For example, customer A wants to allow different machines on the internal network to receive Windows RDP connections inbound.  To make PC maintenance identical between the internal machines, the customer does not want to change the listening port for RDP on the individual PC workstations through the Windows Registry.  The customer also does not want to dedicate separate IP's to each machine in a 1-to-1 NAT setup.  The only option is to have remote connections to each of these PC's to use a different destination port.  So, for example, PC one could be reached on TCP port 5151, PC two on TCP port 5152, and PC three on port 5153.  This requres a firewall that is able to translate each of these connection requests to a different internal IP on the default RDP port (TCP 3389).  So, the following setup is required:
    Port Forwarding with Port Translation:
    Router External IP on TCP port 5151 ---> forwarded to PC One's internal IP on TCP 3389
    Router External IP on TCP port 5152 ---> forwarded to PC Two's internal IP on TCP 3389
    Router External IP on TCP port 5153 ---> forwarded to PC Three's internal IP on TCP 3389
    There are several comparable "small business" class router competitors to the RV042, RV082, and RV016 that will perform this port forwarding with port translation process without incident.  Unfortunately, these Cisco/Linksys small business routers will not accomplish this task currently.
    Please implement this feature in a future firmware release.
    Thanks!

    Excellent.  I see this now.  None of our customers actually use the UPNP feature, so we never realized that Port Forwarding with Port Translation features existed on this page along with the ability to enable or disable UPNP.
    Perhaps, in the future, this functionality could be moved to and incorporated into the port forwarding page which seems to be a more logical location.
    In either case I'm very happy to know that this feature is available on the RV's.
    Thanks for your assistance.

  • LR214 port forwarding / port translation config issue

    I am trying to create multiple ssh tunnels through  LRT214 with portforwarding. - basic ssh tcp forwarding works fine :  I added new service TCP port 22; and than forwarded it from the WAN port to an internal server; - now I am trying to to forward 4 external tcp ports (I am port values values in 5xxxx  range) to four different intenal servers to standard port 22 on each: in portforwarding services I created 4 different TCP (WANip->internalserver[1-4]ip)  and created 4 forwarding entries;in port translation I created 4 port translations  port5xxx1->port22, port5xxx2->port22, etc..opened it all in firewall (tcp ports 5xxx[1-4] are open any to any) when I try connecting to one of 5xxxx ports from the outside I get 'connection refused', port scan shows for all 4 ports 'port closed' What am I missing ?  

    You can use Port Address Translation (PAT) to address your concern. Simply follow the steps below:  1. Add the Service port your device will be listening into. a. Configuration>Setup>Port Address Translationb. Click on Service Management. Service Management window will show up.c. Give the Service a named. Chose TCP or UDPe. Input the External (ex.: 10001)  and Internal (ex.: 22) portsf. Click OK  2. Point the Service port to the device. a. While in the Port Address Translations page, select the Service port in the "Services" drop down menu.b. Enter the IP address (ex.: 192.168.1.11) of the device.c. Put a check on the Enable box.d. Click on Save. 

  • Port Translation (Non to Standard Ports)

    Hi Guys
    I would like some advise/ideas on the best solution for the below.
    I have a application server which uses non standard HTTP/HTTPS ports.
    What I want is a solution to translate these ports to standard ports.
    Client 1 accesses the site on port 80 – from a gateway or something similar – the gateway accesses the application server on port 4466 etc and presents the site to the client on port 80.
    I have various application servers which use non standard ports and want to create a central solution so that all three of my clients will not have to make any changes to the firewall/ proxy servers as to them they will be accessing the site on a standard port 80.
    Any advise much appreciated.
    Many thanks
    Ed

    The translation is from one port to another, not many to one.
    Meaning that we can't redirect all three ports to just one on the outside.
    We have to use one port per IP.
    Would this work if i had multiple ports ?
    Only if you have multiple addresses.
    Like:
    Test1.com:80---internalTest1.com:4445
    Test2.com:80---internalTest2.com:4456
    Test3.com:80---internalTest3.com:8776
    They will allow the traffic through as normal?
    Yes, the clients in the outside will just go to the websites as usual, the whole process will be transparent for them.

    Hi Jorge
    Thanks for the prompt response
    I havent purchase the kit yet as i wanted to make sure what i want to do is feasible
    and also which is the best solution for me.
    I belive  Port Redirection (Forwarding) is the best solution for my ports issue.
    In terms of load balenceing which i will need for this would you reccomned a Cisco ASA.
    Do you think this will meet my required needs
    Many thanks

  • Port Forwarding (Redirection)

    Hello,
    I have a question and need some guidance.
    I have a Cisco ASA 5555-X, ASA Version 9.2(2)4 with ASDM Version 7.3(1)101.
    We have SMTP on port 25 (I know..not secure...unfortunately we don't control it)
    In order to deter spamming, port 25 is blocked and managed by Access Rules in our ASA.
    We have allowed servers to use SMTP for alerting features so we have some gear already configured and allowed to use SMTP port 25.
    I have been asked to allow a handful of desktops to send email out - yes, send only.
    I do not want to allow any desktop to use SMTP port 25.
    Here is my question..finally...
    Let's say my SMTP is 10.90.2.30
    My desktop is 10.0.0.111
    Can I set my desktop application SMTP settings to use port 465, then have the ASA redirect the port 465 coming from 10.0.0.111 to port 25 on 10.90.2.30?
    Can this be done?
    If so, can someone share how this would look configured using ASDM?
    Thank you in advance!

    I read an article on "Converting your $60 router into a $600 router."  I realize that Linksys would not condone or support this.  However, if I were to perform this firmware upgrade, would the router then support what I am trying to accomplish?

  • NAT port translation issues Mac OSX Server 10.6.2

    Hello:
    I'm setting up my new MacOSX Miniserver to be a gateway on my network (displacing an AEBS).
    I've got almost everything working to my expectations, except NAT.
    I've got outbound NAT and NATPNP working no problem.
    I can map a host's service to the NAT gateway (i.e., http://www.mymachine.com --> http://192.168.1.25)
    I CANNOT get NAT translation to work (i.e., http://www.mymachine.com:8080 --> http://192.168.1.25:80). My config looks like this:
    <key>redirect_port</key>
    <array>
    <dict>
    <key>proto</key>
    <string>tcp</string>
    <key>targetIP</key>

    <key>aliasPortRange</key>
    <string>8080</string>

    That doesn't work at all
    but <key>redirect_port</key>

    works like a champ... HEEEEEEEEEELP!

    I think I just figured it out!!!
    I have to enable BOTH of the ports (in this case 80, and 8080) on the firewall...
    Then NAT translation works like a champ!!!

  • Using a content rule for port translation.

    If I set up a content rule to grab traffic on a VIP on port 81, can I then send it to a server that is configured for port 80 ?
    cheers,

    If I receive a udp packet with the sourse port 123. Can CSS forward this packet to the Server, but replace sourse port to something greater than 1023 ???
    As I know CSS doesn't NAT for udp ports less than 1023.

  • BT HomeHub 5 Port forwarding to 2 PCs

    I have two PCs set up with TightVNC server and can access them both perfectly.  One is on <ipaddress>:ort 5900 and the other on <ipaddress>prt 5901.  I have also set up port forwarding so I can access one PC via the internet using no-ip to handle the ddns.  To set this up I selected the application VNC and linked it to the PC.  This works well and remote TightVNC client can log into the TightVNC server on that PC.   The problem is that I have two PCs running TightVNCserver and I need to remotely log into either or both simultaneously but I cannot set up another port forwarding entry as VNC is in use and removed from the list of applications.
    Is there any way to set up port forwarding to two PCs with different port numbers?
    Thanks

    Without getting my HH out of the cupboard to check, is there not an 'other' application that you can assign the port to? Surely the name is just a label it doesn't have to be called VNC.

  • BT HomeHub Ethernet port settings

    What is the recommended setting for devices connected to the Ethernet ports of the BTHH 2.0 ?
    I don't trust Auto-negotiation, should I fix to 100mbps and Full duplex?
    Are all 4 Ethernet ports configured identically?

    Leave everything at Auto and it will be fine.

  • BT HomeHub 4 - Port Forwarding.

    I need to open up ports 80, 8068 on my Home Hub 4, I have followed the port forwarding instructions but it will still not open them.
    I have opened up ports 9000, 85, & 18004 in the same way and this has worked?
    Any advice?
    Cheers.

    Traffic will only be allowed back in on port 80 from a source if your device has already sent traffic to that source, because port 80 is used pretty much everywhere for http traffic and leaving it fully open would be just asking for trouble - it's pretty much a given that one of a limited number of browsers is sat at the end of it.  I'm assuming that 8068 is similarly restricted.

  • Homehub 5 port forwarding for Windows Homeserver 2...

    Hi
    Has anybody any solutions on setting up the HH5 for Windows Homeserver 2011
    I've inputted all the rules manually as WHS couldn't complete the task, to find ports 80, 443, 4125 remain closed after manual input.
    WHS reply's with UPnP not working / router not working.
    BT customer services quite appalling and I'm not paying for Tech Support as the package is only 6 months old and I feel I shouldn't have to pay for a product that isn't working correctly, if it was over 12 months I understand I should pay.
    I've manually inputted and setup port forwarding for my Iphone app and Android and they've finally started working.

  • Node redirects to self with incorrect port

    Hi!
    Here is a RAC (11.2.0), with 3 SCAN IP addresses (A1, A2, A3) and nodes N1 and N2. Node n1 is mapped to A1 and A2, while N2 to A3.
    When connecting to the SCAN hostname (or any of the addresses directly), most of the times everything is ok. But sometimes as I see in sniffing, I get a TNS Redirect to a new HOST+PORT.
    Now, what is interesting, that from N1 the redirection is to N1:XYZ (yes, the same machine), and from N2 to N2:DEF. After listing open ports, I can see that
    N1:DEF is bound by the process ora_d000 on TCP, while N2:XYZ is also bound by the process on the other machine.
    That is, in the redirect I somehow get redirected to the wrong machine, since the IP and the PORT of the instances are mixed. Some questions:
    1) Is it normal to redirect to a port non-1521? DEF and XYZ are high ports, seemingly random.
    2) What controls if I get redirected or not? Is this connection load balancing?
    3) What could cause the symptom? What config options should I look into and where to resolve the correct machines/ports on redirect?
    Pretty new to Oracle, so please don't assume much knowledge. Thanks!
    Ron

    After taking tcpdump both on client and the nodes, I discovered the following:
    When connecting to N1, the redirect message it sends, captured:
    - On the server-side: HOST:PORT=N2:<port for N2>
    - On the client-side: HOST:PORT=<ip-address of N1>:<port of N2>
    Maybe there is an application-level firewall sitting between the node and the client, which mis-translates the message?
