Opening Port 123 on my Linksys BEFSR41 Router

Hi

I am trying to use an NTP client (Simmtime) to get the time off the web but port 123 is getting blocked by my Linksys BEFSR41 Router.

Can you tell me how I can unblock port 123 in my router so Simmtime will work?

Thank you
Brad McMillan

    Hi Chase:

    I think it is just port 123, so I guess the range is 123 to 123. The protocol is NTP which is UDP.

    BTW, since I posted my question I did the following as a result of learning more about the BEFSR41:

    I went to "advanced->forwarding->UPnP Forwarding" and entered

    Ext Port: 123 to 123
    Protocol: UDP
    IP Address: 192.168.1.101 (which is the address of my computer with Symmtime running)
    Enable: checked
    Apply

    But my Symmtime still cannot connect to the NTP server.

    Thanks again,
    Brad

    Hi Brad,



    Before opening ports on your router, do you know if there are any ranges and if its TCP or UDP or both?

Hi:

It turns out I didn't need to open port 123 on my router to get SymmTime to work.

Thanks for the efforts

BL-C131 port forwarding.


So you've configured port forwarding on the router. Do you have any anti-virus applications installed or have your set an exclusion in Windows firewall?

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.

Need proper setup for linksys befsr41 to xbox


If the router is already set up, all you should have to do is run cable from router to xbox. Xbox should be set to automatically detect settings.

Linksys BEFW11S4-RM 4 port wireless router


This is an old router. Look at the power light. You must have a STEADY power light. RESET the BEFW11s4 by pushing the reset button for 30seconds. Unplug the power of the BEFW11s4 for 30 seconds. Connect pc to port 2 or 3. pc should get an ip of 192.168.1.x. If you are getting this ip that means that the pc is already detecting the router.

Good Day

NAT


First, you need to get into the user interface for the router.  To do that, just open your web browser, type in 198.168.1.1 & hit enter.  A login prompt will pop up if you're able to access the router.

If you've never done this before, the username is blank & the password is admin

What, exactly do you want to do with the NAT firewall?

To enable/disable NAT: click on setup, then click on advanced routing.

To filter Internet NAT redirection: click on security, then click on filters.

You can find this information in the User guide provided by LinkSys at:

http://www.linksys.com/servlet/Satellite?c=L_CASupport_C2&childpagename=US%2FLayout&pagename=Linksys%2FCommon%2FVisitorWrapper&cid=1166859876500&displaypage=download

Select your version number, then click on User Guide when it comes up.  User guides & Interfaces for the BEFSR41 are almost identical on every version.

VPN


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 192.168.5.100. 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.
