HELP: can connect, but cant browse network

Postby jpderooy » Jul 01 05 11:25 pm

I finaly setup VPN. I run VPN on the file server and setup wingate on the internet server to let trough TCP and UDP port 809 to the VPN server.

When I want to connect from a client over the internet to the VPN server, everything works ok. I can connect and the VPN server accept the connection.

On the client side I see a conflict: Published routes (x.x.x.x) (In conflict).
I try to install the RIP tool, but still can't browse the network.

What can I do to fix this?

it means that you probably use the same address space on both sides - for example, your server side uses 192.168.0.x address range and the same is configured on the client - I'd suggest that you re-configure the client machine and assign an IP address from different subnet (say, 192.168.1.x).

I have my client put in the 192.168.1.x range and there are no conflicts!

But: I still cant browse the network. I installed the VPN only software on both the client and the server and I installed the RIP tool on th eclient only.


What to do?


PS. Post a screenshot to show you the settings?

You do not need RIP client on a machine where Wingate is installed.
Now, can you ping this server-side machine?

This is the situation:

At office:

- DSL Modem (port 809 tcp/udp forwarded to Internet Gateway)
- Internet Gateway running Wingate 6.0.4 std.
- File/app server running Wingate VPN

Client site (remote over the internet):

- Wingate VPN + RIP tool
=============================

I changed my remote clients' ip range and there are no conflics now and I can connect. But I still can't ping or browse the office's network.

What to do?

Then first thing to do is to make sure that UDP traffic is redirected along with TCP port 809. Please, double-check this. If it is properly redirected, then the problem may be in the driver - if you give me your operating system for the machines you run both VPN node (client and server) I will send you the new drivers for them.

On the DSL Modem I let through both UDP and TCP port 809 to the wingate machine. On the wingate machine I configured the firewall to redirect both UDP and TCP port 809 to the wingate VPN machine. This is double checken and as far as I know ok.

VPN client runs on Windows XP and the VPN server on a Windows 2003 SBS.


Hope you have a suitable solution!

Have you received it? I am a bit worried your mail server might refuse the attachment.

Installing the driver on Windows XP works fine, but when installing the driver on Windows 2003 SBS is a problem. The server boots but the normal windows clients can't acces the server anymore. So not only VPN isn;t working but the normal network is down too!

Hope you can help me here!

Ok, then - restore the backuped driver on this 2003 machine (server), reboot it and try again.

Hi,

Looking at your published routes it looks like your VPN is set to local machine access only, you're not publishing the route for the LAN, just the server. You can check this by going to the VPN properties and looking at the local participation setting, it should be set to local network.

It looks like the WinGate server is accessible, but that's just a guess because you've blacked out the machines. Having only the WinGate VPN host server accessible is consistent with the routes that you're exporting.

Hi, these settings are ok.

I installed wingate and wingate VPN on one and the same server (internet gateway).

So we have:

router -> Wingate + VPN -> file server


I CAN connect, no problem there, but some machines can ping to the server and other (connected through anotherdsl modem) can't.

What is the work-around for setting up the client and how to configure the DSL modem the employee has at home?

Depends on the types of DSL modems - if they are plain dialups, then nothing special should be done unless these modems have built-in firewalls - then port 809 TCP and UDP should be open. If these DSL modems are routers, then the new driver should be installed on both sides.

they are routers....NAT DSL modems.

I have disabled allof this on the server side (let wingate configure the firewall). Do I manually open 809 on the client side? Even when we ude NAT?

That's the problem - if inbound port 809 is not open (usually on the server side) than the clients cannot initiate data channel that uses port 809 UDP. On the client side the standard driver might experience difficulties because of the internal port conflict - that's why the new driver is needed.

ok, can you please give a simple work around? Mention: I have no extra drivers installed and nothing configured.

DSL modem (firewalled etc) -> Internet gateway with Wingate and VPN


I put all trafic from the DSL directly to wingate...and wingate firewall opens 809. What to do (install) server side and what client side.


Thanks!

Ok, now - you've got this new driver, haven't you? Simply install it on both sides and give it a try.

the wingate/VPN server isn;t the windows 2003 server anymore. It's a Windows NT4 server. Is that the same driver? And what to open client side on the modem/DSL router?

No, the drievr is different - I'll email the new one to you. On the client side try it first without opening any ports - the client should initiate all the connections automatically punching holes in DSL firewalls.

Hi, Ricardo

I sent the new drivers to you this morning - did you receive them? I was a bit concerned because quite a lot of people had their spam filters tuned to discard messages with potentially executable content.

The new driver requires now the new engine - we are about to release it, so it'll be a couple of days before new software is available.
