Question about SMC Barricade 7004 Router

Trying to get VPN to work but not sure what fields to fill out to open ports on router. There is a previous post about opening some ports but I'm not sure what to fill out in all the fields or what it is looking for. I'm trying to VPN into work from home. VPN is setup correctly. This is an older router but i never had need for VPN until now, SMC won't even support it.

How do i open udp prts 53,67,68,500,4500 on a linksys wrt54gs2 router

Judging by the port numbers you listed, you are trying to setup a VPN tunnel to a corporate network. If this is a client based VPN, you actually don't need to open these ports at all, given that the router will allow all traffic outbound, by default. However, if you are trying to build a site-to-site VPN, your Linksys router isn't capable of this.

Now, I suppose you may have a device inside your network, behind your router, that is running some VPN software of some sort. In which case you want to turn on port forwarding. This can be a complicated task. Please comment, if that is the case and I will go into more detail.

Wrt160n vpn error 800

Error 800: Unable to establish VPN connection

This issue may be caused by a router that has outdated firmware.

Make sure that port 1723 is opened on your router.
For VPN connection , you can try opening port 500, 443-447, 10000-20000 and important port 1723 on your router.

I will suggest you to upgrade firmware on your Linksys router.
After upgrading the firmware, reset the router to factory default and reconfigure it manually.
Open the ports mentioned above and see if that works.

How do I setup our router to allow VPN client?

you are trying to connect to the VPN client.
Which VPN software you are using ?
To connect to the VPN , you will need to trigger ports on the router.
open the set up page of the router and trigger the ports on the router. The port numbers will be. 1723 , 10000-20000 , 443-447 , 500. Also reduce the MTU settings to 1365.
Disable the Block Internet request, you will find this option under security tab.
Make sure that the firmware of the router is up to date.

WRT120N doesn;t permit VPN accesses

Most times when VPN is not working is because one of the ports is not forwarding right. Easy fix is to go to router settings and enable DMZ for your computers IP address. Also you can actually find out what are the ports this VPN uses and go to Port Forwarding part of router and open the ports manually. My favorite is DMZ. All this does is open up ports for your computer IP address so there is no blocked pockets. Good luck.

Problem with VPNand Linksys router WRT150N

If that is the case you may forward ports on the router for VPN connection, try to open 47, 500 and 1723 all TCP and UDP protocol.

Here's what you need to do, check the IP address of the computer where you have the VPN software,

here's how:
click start> run> type cmd> hit okay
on the black screen put in ipconfig and check the IP address there,

> when you get the IP address then we can enable port forwarding on the router

> open IE on the working computer on the address bar, type

> nothing for username and password is admin in lower case

> then click on the applications and gaming tab on the router,

> and from there, example of how to field that in is like this,

> for aaplication name - VPN1
> for port it is 47 to 47
> for protocol it is BOTH
> for IP address ex. 192.168.1.XX -
> then check enable, do the same thing for the rest of the port.
> save the settings and try it again after.

> if it is still nothing, you may connect the computer that has the VPN connection directly to the modem and check if you will be able to connect via VPN

i'll wait for your response, thank you and have a nice day!

VPN Passthrough Configuration

1. Please assign an IP address to your computer using the IP Address Reservation.

a. Please open any web browser like Internet Explorer or Netscape Navigator.
b. Connect to the router by typing or in the address field and click Enter or Return key.
c. A window will prompt for a user name and password. The default username is "admin" and the default password is "password".

Note: If it does not take password as the password, you might have changed it when you have run the NETGEAR Setup CD so please try other passwords. If you cannot remember the password, you need to reset the router and run the Setup CD to reconfigure it.

d. On the setup page, please click LAN IP Setup under Advanced tab.
e. Click Add under Address Reservation then you will be brought up to a new window.
f. On the Address Reservation window, please select the radio button of the computer you wish to add.
g. If the computer you want is not on the list; click the Refresh button to update the table.
h. If the computer is still not on the Address Reservation Table; please enter the IP Address, MAC Address, and Device Name of the computer you wish to add.
i. Please click on the Add button when finished.

2. On the Set Up page of the router, select on Port Forwarding/Port Triggering under Advanced tab.
3. Click Add Custom Service and type VPN on the Service Name box.
4. Set the Service Type to TCP/UDP and input the VPN port numbers under the Start and End Port field.
5. Type in the last digit of the IP address of your computer. Then, click the Apply button.

Example: The IP address of the computer trying to establish the VPN connection is

Service Name Start Port End Port Server IP address
VPN1 47 47
VPN2 50 51
VPN3 500 500
VPN4 1723 1723

the following is from a nice guide i found on the net, see if it works for you: First thing to check is whether your router has any settings for PPTP or IPsec "pass through". These are commonly found in Linksys routers but you may have to hunt around for them on other makes. All you need to do is enable the setting for the VPN protocol that you're using, reboot your router and, if you're lucky, the VPN connection will come right up. Note: Not all routers have these enables and the lack of them doesn't necessarily mean that you can't get VPN working. Open up that Firewall Still no connection? The next step is to try opening some ports in your router's firewall to get your VPN connection made. In each case, you'll need to open the specific ports (and protocol) to the IP address of the computer that you're running the VPN client on. NOTE that port mappings work with only one computer at a time. If you have multiple VPN clients that you need to connect, your router will have to support the VPN protocol that you're using without requiring ports opened. If you're using Microsoft's PPTP protocol, TCP port 1723 is the port you'll need to forward to allow PPTP control traffic to pass. Figure 2 shows the Forwarding screen on a Linksys BEFSR41 set to forward this port to a client with IP address PPTP also needs IP protocol 47 (Generic Routing Encapsulation) for the VPN data traffic itself, but note that this is a required protocol, not a port. The ability to handle this protocol must be built into the router's NAT "engine"?which is true of most present-generation routers. IPsec-based VPN's need UDP port 500 opened for ISAKMP key negotiations, IP protocol 51 for Authentication Header traffic (not always used), and IP protocol 50 for the "encapsulated data itself. Again, the only "forwardable" item here is UDP port 500, which is also shown programmed in Figure 2 to the same LAN client machine?protocols 50 and 51 must be built into your router. Tip: Not all routers are created equal! Some allow only one VPN tunnel to be opened and used by a single client. Others support multiple tunnels, but with one client per tunnel. Unfortunately, most vendors don't make the VPN pass through capabilities of their products clear in their documentation, nor do they have support staff properly trained to provide this information either. In most cases, your only option is to try a router in your specific application, and make sure you can return it and get your money back if you can't get it working. Still not Working? Getting many IPsec-based VPN setups working can be a black art due to the wide variation in techniques used by various vendors. Although IPsec products have become more uniform as the technology matures, your company may use older, more proprietary products that may not be configured with NAT in mind, or require additional ports to be opened in your firewall.
