• Need help with the implementation of a VPN to bypass the port forwarding to access my web server

  Pretty much as the title suggests, but it's probably not clear enough. Let me explain:
  I want to host a Web site on my computer. Not another major, but something small and private.

  Before you set up a domain name, I want to make sure the site works - which it is not.
  I am currently using WAMPServer to organize it all.

  I put it so when I connect to localhost, I have access to all my files in the directory, regardless of whether or not I'm "online" or "offline" on WAMPServer (or not, others will have access to my Web page).

  When I turn WAMPServer 'on-line', it allows the connection of my WAMPServer homepage through both localhost and connection through the static IP address, I put in place, but only in LAN, meaning that only computers connected to my home network would have access to the page.

  My router cannot be configured to allow port forwarding for can I open a port to allow redirection to my computer, rather than the ambiguous router itself. As an alternative, I downloaded Hamachi to allow a computer to connect to the VPN (Hamachi) and, by extension, my IP for access to files in the directory.

  In theory, it should work, but it didn't. In my local network computers could still connect to the IP address, but the computer in the virtual private network, but not on the local network could not.

  Is there something I'm missing here, or is there any suggestions to make this work?

  Note:
  My works of static IP as what it is, however, it is different from the IP address used in Hamachi. If I change the IP address used by my computer to access the site to the IP address that uses my Hamachi, would that work? As another suggestion, can I change my static IP setting is automatic and change one used on WAMPServer (from localhost, allowing the connection to bring) than on Hamachi? Or I do all three IP addresses the same?

  Thanks for all the help and solutions,

• VPN and port forwarding problem

  Hello

  I configured a VPN (IPSec) between 2 sites on Cisco 881 - K9.

  The server 'A', which the 192.168.0.X address must be accessible on port 80, 8080 and 90 of the public network.

  I have configured the ports of shipment with the command:

  IP nat inside source static TCP 192.168.0.X 90 interface fastethernet 4 90

  IP nat inside source static TCP 192.168.0.X 80 4 80 fastethernet interface

  IP nat inside source static TCP 8080 interface fastethernet 4 8080 192.168.0.X

  The server is accessible from the outside, the site in which it is located.

  But there is a problem with the second site:

  • I ping the server with its local address 192.168.0.X
  • But when I try to open a Web page that is using port 80 or 8080 or 90, the server appears inaccessible

  It seems that the problem is due to the translation of port because when I delete the configuration of port forwarding is no problem over on the second site.

  Thanks for your help

  Hello

  You need conditional NAT.
  When you want to Port Forwarding to work just for a part of traffic, e.g. when access to the server from the Internet
  but not for traffic entering via VPN, you can add a roadmap to the end.

  Thus,.
  IP nat inside source static TCP 192.168.0.X PUBLIC_IP 4 xx xx map route VPN

  The road map tells when it is NAT that will to spend.
  It will always happen, but when traffic is coming from the VPN.

  Now... the problem is that you can add a roadmap, when you have a rule of Port forwarding to an IP address (and not an interface).

  Anyway, give it a try and let us know.

  Hello

  Port forwarding is different to allow ports through the firewall. I guess you meant allow tcp/21 and 21 1024-2774, right port?

  You need the following lines

  access list allow component snap permit tcp any any eq ftp

  access list allow component snap allowed tcp everything any 1024 2774 Beach

  You can be more specific and can replace "any" with the actual IP addresses

  Thank you

• Automatic EA6500 for PokerStars port forwarding

  When I play poker online I am sometimes disconnected. The network status report showed that it is because of my router. They recommended that do the following:

  Please set the trigger (automatic port forwarding) for the following ports: 26002 and 443 22.

  The access router configuration page and follow the instructions as a guideline.

  Click the Advanced tab.

  Click the app button

  Click the enable button

  Name of PokerStars

  After the outbreak of Port, enter 26002

  After the trigger Type, select TCP

  After the Public Port, enter 26002

  After Public Type, choose TCP

  Click on apply

  Repeat to ports 443 and 22

  In the Linksys Smart Wi - Fi, under Security, I went to the apps and games to find the port forwarding and triggering, but I don't see how I can implement a port as an example here with a public port. Can someone explain? I have little knowledge about this kind of thing. Thank you!

  First, you must go in the DHCP server setting and to reserve an IP address for the main device that you use to do this.

  Then in simple port forwarding using that IP address and the same port number for internal and external. External port, that's what they call public port.

• Port forwarding to another local subnet on RV130W

  I just replaced a RV120W with a RV130W and I'll have set up some of my port. I have the router as gateway on a subnet. Off this subnet are one number of other subnets reached via static routes.

  When I try to convey my mail server SMTP I seem not to be able to assign the address before anything else than the subnet the RV130W is on. Any reason, this feature is gone or have I missed how to configure?

  Bob,

  Hello, I hope you do well.  I tested this configuration in the lab and it seems to be a limitation of the device.  Whereas the RV120W done port forwarding through access rules that allowed for any address to be entered as destination, the RV130W will throw an error if the port destination address is not on the default LAN subnet.  Have you tried setting to the top of your other subnets like VLAN, rather than using static routes?

  Kind regards

• WRVS4400n (SSH access) port forwarding

  I have a WRVS4400n and a Server CentOS that I need to access SSH from WAN.

  I've created a single port rule to forward to open port 22 and pass to the server (whose address is 192.168.41.3)

  However ssh connect can't, 'ssh user@{external_IP}' command times out after 20 seconds.

  I was wondering why...

  If I connect to my server directly to the modem through the external interface - I have a problem to connect to it. Once, it is behind the router - no luck.

  I even added same rule for UDP, don't know if it's necessary, but it did not really hepl.

  The router is on the version of the firmware 2.0.1.3, on a background version is 2.

  Any suggestions?

  Centre,

  The server does not respond to the front port is because if the traffic is unknown to this subnet it is not sent to the address 41.1 looks. If you can not ping any what other subnet, then the local LAN subnet on the server you will not be able to communicate with a public IP or even a PC via a VPN tunnel, address because the destination IP address is outside the LAN subnet. The reason to ask if the server can ping internet.

  Is it possible to remove the default gateway on the eth0 interface, just in case it is causing problems with the statements of the route on the server.

  What is a linux server?  If yes you can run the command-line - n to see what looks like your routing table?

• NETGEAR ProSafe VPN Firewall SRXN3205 and port forwarding?

  Hi, this is a long shot, but I'm pulling my hair out at this point and can be a bit over my head, as I am new on network

  Small short story, I have two servers, one is the NAS box (IE if I connect via the internet to the site via public IP network from home, I get it that site says 'my actions' I insert login and pass and get access to them.)
  That is, everything is peachy.
  The problem is when I try to connect to my FileMaker Server I'm not and instead, he takes me to the login NAS box. So I think ok, I need to port forward (5003 for filemaker) to go to different PC local LAN(192. etc)

  Security > firewall > Add Service entering:
  Service: fmserver
  Action: Always leave
  Send to LAN Server: unique address 192. etc is filemaker installed on (and different on a NAS)
  Definition of Port number: 5003<-- is="" this="" right?="" how="" else="" would="" you="" indicate="" you="" want="" all="" connections="" on="" this="" port="" to="" go="" to="" this="" specific="" lan="" machine="" from="" internet="" instead="" of="" default="" which="" seems="" to="" be="">
  rest is default, I click on apply.

  Here's what I don't understand. In the table of incoming Services, (security > firewall) I have two local IP in the list, a SIN, the other for Filemaker. But only the top works and can be connected to. I can move every top position and it will work, but they will not work at the same time, just the one that sits on the top of the sad Smiley page

  and yes I read the manual again and again and don't know how I'm screwing up the port forwarding on this point, even if I am brand new to probably something stupid Smiley Happy (our work IT guy is gone so tried to get involved through this somehow)

  Any help would be appreciated.

  Hello sinieq,

  There is a hierarchy on incoming service table, which is normal. I see 4 services added using "ANY" (ALL use any port number) you will need to remove/disable these because of the rule of the hierarchy on the table, all other services will be ignored when EVERYTHING is used. What is the port number used by the NAS Server? I don't see a port defined to access NAS. Try disabling services by using "ANY" and try again by adding the translation to the port number of the NAS.

  Let us know what happens.

  Thank you

• RV220W and Port forwarding

  Hello

  I have a problem with my Cisco RV220W with Firmware 1.0.3.5

  I have in my local network a Dreambox with the IP 192.168.1.230, he listen Port 8880.

  How can I implement a WAN port forwarding to the Dreambox?

  Thank you

  Michael

  Hi Michael,

  Thank you for posting. Please follow the steps below to transfer the port to your Dreambox:

  1. Log in to the router, then go to: Firewall-> Access Control-Services > custom.
  2. Press 'Add' and then type Dreambox name, TCP for type. The Port of departure and Port of finish will be 8880. Press "Save".
  3. Go to the IPv4 firewall rules and press 'Add '. Use the following settings:

  Area: No reliable (WAN)

  Area: Trust (LAN)

  Service: Dreambox

  Action: Always allow the

  Source host: no

  Send to the Local (DNAT IP) server: type the address LAN IP of the Dreambox here device (i.e. 192.168.1.150)

  Ignore the other settings on this page and press 'Save' at the bottom. You should now be able to reach the Dreambox from the Web using: 8880

  Please let us know if it works or if you need further assistance.

• SSH port forward in upcoming white

  I am trying to set up a connection to database via a hopserver using SSH port forwarding, as described in the article by Jeff SSH Tunnel with #SQLDev 4.1 EA1 and ai2 side by side .  I have screenshots, but don't want to publish sensitive information in the forum - where the descriptive text instead.

  I have 4.1.0.18 SQL Developer build HAND - 18.37 (ai2), identical to his article.

  My laptop with SQL Developer (internal corporate network)

  My-jmpbox-01 (linux hopserver that I can ssh to)

  prod-db-01 (Server database DB on port 1521 of housing)

  From my laptop, I can't not directly to the prod-db-01.  First of all, I must first SSH to my-jmpbox-01.

  Therefore, in the developer SQL 4.1 ai2, here's what I'm trying to do:

  Display-> SSH

  click right-> new host SSH SSH hosts

  Host = my-jumpbox-01

  Port: 22

  Click OK

  Back to the host SSH window

  my_unix_user@my-JumpBox-01 right click-> TEST

  
  Enter your regular LDAP password

  Click OK

  Back to the host SSH pane:

  Click right my_unix_user@my-jumpbox-01 -> New Remote Port Forward

  Name prod-db-01

  Host: prod-db-01

  Port: 1521

  automatically assign the remote port

  Ok

  should now look like this:

  prod-db-01. right click-> CONNECT

  password

  and OK

  now move your mouse over the line of prod-db-01 and I see a DISTANT PORT (which probably indicates that he got a course valid tunnel).

  Back in the connections (top left) pane

  Click + icon (new connection)

  Display "new database connection:

  login name: prod-db-01

  user name: scott

  password: *.

  connection type: SSH

  Under the Port Forward Dropdown, I don't see the my_unix_user@my-jumpbox-01 or the prod-db-01-connection. It is completely empty.  The troubleshooting steps I can take? has anyone else seen this problem before?

  > Click right my_unix_user@my-jumpbox-01-> new remote Port Forward

  You want a LOCAL port forward

  Take a remote port, for example, your database server network traffic and forward on the SSH tunnel to another destination, say to your client computer.

  An attacker Local port would take your jdbc via SSH traffic to a another machine before a database connection was attempted.
