hi,

Ive just created a VPN and connected sucessfully.

However, ive noticed its not quite performing correctly.

1. I cant use the internet when connected to the server (locally or remotely, no internet at all)
2. i cant find printers on the remote local server
3. i cant ping local hosts remotely
4. nothing appears under the "network", i thought the network name or host name would appear under network and allow me to browse shared documents, eg, COMPUTER_NAME in "networ"

however i can map network drives.

Any help much appreciated,

Cheers
 
I think the problem is you firewall, maybe not the local, but the network FW.

Can you provide what kind of VPN are you using (Windows, Cisco, ...), which protocol (L2TP,...) and if other users don't have this problem.

Cheers
 
Its currently only me using this VPN while in testing

Its over windows with port 1723 TCP forwarded on a SMC router. The VPN server is server 2008 and protocol PPTP.

Ive got the internet issue sorted, but still cant find any printers,

However whwn i ping the printer (192.168.1.200) i get a reply from xxx.xxx.xxx.xxx: destination host unreachable

And when it pings for some reason, changes the IP to 192.168.1.4

Thanks for your help!
 
one more thing, when i ping the printer 192.168.1.200 i get reply from 192.168.1.200:Destination host unreachable
and it displays the ip address 192.168.1.4 like its changed it?

Thanks
 
I think the problem is your network firewall which is blocking some ports and protocols. For example, you should enable ECHO REPLY / ECHO REQUEST in order to receive an answer from the printer.
 
When you are local... WHERE? On the "office" network? This is correct, on LAN usually you don't have to pass a firewall because of you are on the same LAN. When you use VPN you create a tunnel and sometime the firewall blocks other communications channels.
 
So what would i need to configure in the firewall to enable this

Just odd i cant find printers either. Its not really working as a VPN yet

Also windows firewall is disabled and i dont really use the router firewall

Would this require setting up routing?

Thanks again!
 
so reading a bit further, i found i may need to forward Protocol 47 GRE.

However, in port forwarding, only TCP and UDP are avalibale protocols for forwarding.
I have a SMC Barrigde router.

thanks
 
I don't think this will solve the problems with ping and printer but try the following procedure: (from technet):

To prevent the new default route from being created, select Internet Protocol (TCP/IP) on the Networking tab for the properties of the VPN connection. Click Properties, and then click Advanced. In Advanced TCP/IP Settings, on the General tab, clear the Use default gateway on remote network check box.
Click to expand...

Check this:
Go to network and sharing center and click advanced sharing settings on the left, see if there are any profile which block network discovery.

If you type the IP address of the print server, can you see printers?

Regarding the PING it's still strange, anyway, from your client to your server ARE THERE ANY FIREWALL? Correct?
 
box use default gateway on remote network is already cleared.

when i try my printer IP, Which is 192.168.1.200 (thats the local address)
it says

reply from 192.168.1.4: Destination host unreachable

and changed the ip address to 192.168.1.4 from 192.168.1.200

also, no printer can be found if i add network printer

thanks
 
Ok, so the problem may be your routing table.

Tell me:
Your LAN address
Your VPN address
Post the output of "route print" before connecting to VPN and then post the same command AFTER the connection.
 
Could you explain how to do this

Im sorry this is a learning curve to me

I have however just found the server was assigning
Vpn connections static ips not assigning over DHCP?

Not sure if this would make a difference

Thanks for your patience
 
No difference (I think).

Open a command prompt (cmd) and type:

ipconfing /all && route print
then connect to the vpn and do the same:
ipconfing /all && route print

Thanks
 
This is route print before....

Thanks!!
 
Excuse me, what is your VPN Address (IP)?

From what I can see, you LOCAL NETWORK (your computer) is on 192.168.1.0 and your office network (where the VPN is connected), is 192.168.1.0. If so, I think the problem is that you router actually doesn't know where to send packets.

Let me know.
