Question about Efficient Networks 5950 SHDSL Business Gateway Router

1 Answer

VPN client Hiya, I'm trying to establish a connection with a VPN client. The client works on my laptop elsewhere but not at home so it was suggested that the router is the problem, and probably the router's firewall is blocking VPN traffic. Apparently i need to open some ports and allow an ESP protocol but i don't know what this means or how to do it. ("You need to open ports 500 and 4500 and allow protocol 50 (ESP).") How do I do this? And on which computer, as there are 3 hooked up to the same router (my laptop plus 2 desktops). Thanks! Susan

Re: VPN client

Susan, if it is true that the router's firewall is blocking this traffic, you need to access the configuration of the router and open those ports up. Every router is different though, so I cannot just tell you generic'ly how to do this... So, what is the manufacturer and model of the router?

And to Vij.. did you hold down the reset button for up to ONE minute? this is a Hard Reset and will clear the firmware of most models.. just pushing the Reset button and releasing is known as a Soft Reset, and will NOT clear the firmware...

Base from the description of your problem this issue has something to do with the firmware of your router, so to correct the problem do a firmware upgrade on your router or if there's no updated firmware you just flash the firmware to it then check if the problem is already fix after doing that.

Can I establish a VPN Client Access with the motorola wr850g router. The ones at the college being used , routers that is, are Lynksys and are new ... AM in a rut here !!!!

you should but the question is: are you are authorized?
my understanding is that vpn connections usually required a client and you definitely need authorization configured on both ends.

attempt to configure the client in xp as explained here
consult with the adminstrator of your vpn lan site if there are any port forwarding that you may need to configure on your router.

good luck!

Belkin N1 F5D8231-4 V3000

are you running the Cisco VPN client from home, where this Belkin is your gateway and connecting to say your work?
If so, have a look in the settings of the Belkin to see if you can enable VPN Pass-through.

Try disabling some of the firewall functions on the belkin to isolate the issue and turn the rest back on.

If for some reason this model doesn't work even after the above, try changing the VPN client's connection settings,there are only two to choose from... (click modify on your connection entry, go to the Transport tab > then choose from:
IPSec over TCP and IPSec over UDP (port 10000)

I have a belkin router f5d7230-4. whenever i plug in my laptop from work to vpn to my jobs network, it wont go through. i had it working before and i havent made any changes since that time. in the...

The UDP flood suggests a possible DoS (Denial of Service) attack which hoses your connectivity but doesn't harm your PC or change anything. Can you surf the web through the Belkin okay when not VPN ing? Is it just your VPN connection that doesn't work? Do you get any message or dialog boxes popping up when you try to connect saying anything about the remote host not reachable or you username/password is not valid. You VPN client should be giving you some indication of the failure to connect. Any other PC at home to VPN to work with? Also possible that your PC has been denied access to work because your PC caused problems on the corp network. You probably would not be aware of that. Is there an IT department at work to support you?

VPN connection - Client cannot connect

Hi mwells960

Theres alot of differnet things i could ask you, but im going to assume you're jsut setting up a basic VPN. That means that somebody is telecommuting to work and wants to hit the server at work.

That means you have a static ip at work, and your at home workers has whatever, a internet connection lets say. Im thinking DSL with ATT since its a netopia 3347N.

If the netopia has a gui interface, you cant vpn thru it. Its not a VPN router. Its a residential router that you're trying to make do too much.

The sad news is, you can't upgrade it to an Enterprise having firmware router anymore, netopia use to offer that, but when Motorolla bought them out last year, they did away with that nice little feature. For true VPN'ing with a router, first, go get a VPN router to start with.

Most people accomplish what you are doing by putting the netopia in to bridegemode, and then putting a VPN router like a linksys behind it.

Cannot connect to SonicWall VPN

My guess is that dhcp is using the same private network scheme. Try changing your home network scheme to something different than your office.
For example:
Office = 192.168.1.x
home = 192.168.2.x

DI 524 Router Not able to connect to office VPN on Wireless

I have the same model router at home, just checked the settings, you should be able to pass through the router with a normal vpn connection.

If you use a special VPN client, like a CheckPoint Secure VPN client, the router might block it. Also you might want to ask your office's sys admin if you are not blocked by the firewall or something similar. Your office's sys admin will prolly solve your problem since he knows your work network's configuration and setup and how to connect to it.
