How to setup a VPN with the Netopia 4652 DSL Router

I'm a Controls Engineer who has a client that has requested that I be able to connect to their in-plant network remotely. They use a Netopia 4652 for shared internet access only (at this time).

Their network does not have a domain controller present, but is populated with a NT 4.0 server and several other machines running W2K, Win XP and 98SE. There are a total of nine machines on the internal network behind the Netopia firewall.

What I need to do is access the shared directories of several of these machines as if I were plugged into their network on-site... but do it over the internet (assumedly using VPN). I use a cable modem with a Linksys BERF41? (from memory) at home on a XP machine.

I can see the Netopia's setup screens on the local net via telnet, but I have absolutely no idea how to set this up. Can somebody help?

Is the Netopia a hardware VPN server or do I need to setup a machine behind it? If so, what's the best option for doing this in what's basically a peer-to-peer networking setup? What do I need to do in the Netopia Setup?

Thanks,

John Kelley

The netopia 4000 series is capable of being a vpn endpoint so that you do not need a server behind it. You can download the netopia client and configure the router to authenticate you. http://www.netopia.com/en-us/support/technotes/hardware/NQG_054.html Will help you in setting up the client. I would edit my lmhosts file for name resolution on the remote lan since there will be no dns or wins to do that.

The guide you referred me to appears to be for unsing Safenet Softremote as a client. I am using the standard Windows set-up and appear to have done something right using Netopia's http://www.netopia.com/en-us/support/technotes/hardware/NQG_022.html help document... the client appears to connect but I get a error 619...the specified port is not connected. This occurs after a short wait while the dialog displays "Verifying user ID and password". There are no filters enabled on the router.

Any more suggestions...

Thanks,

John

You are running a private ip address on your end? Also make sure the netopia firmware is up to date. Does it cost extra for the softremote client even if you have the netopia hardware? If not I would go ahead and run that.

The Softremote client is $150.00. I'm not certain of your question "... running a private IP address on your end?" As the remote client I am using a cable modem with a Linksys router.

Now, in playing with this thing some more it appears to connect and then immediatly disconnect. That is also what's reflected in my XP event viewer.

BTW, I've tried the connection with-or-without the linksys but the results are the same... a quick, apparently successful connect and then an abrupt disconnect.

HELP.. this is driving me CRAZY!!!

I always thought if you bought and used the netopia vpn device you are given licenses for x amount of software cilents. I guess this was erroneous information. Do you have ipsec passthrough enabled on your home linksys? Also what firmware are you running?
