Accessing Folder Shares via VPN

Posted on 2007-07-25

I have a VPN setup between a  Netgear and a Linksys router. I can ping devices on either side of the VPN both ways. However, when I try and access a file share on a server, I get the message "No Network Provider Accepted The Given Network Path"

This happens both ways. Other VPN traffic is working fine, I can use SQL Server Management Studio to connect to remote SQL servers, I can connect to an Exchange server, HTTP sites etc, but I cannot share files and folders.

This has been working fine for a few weeks, but I am now getting the error. I presume it could be a firewall problem, but am not sure what I need to change and where.

Also I notice in the VPN log that it constantly logs:

Wed, 2007-07-25 10:24:27 - [USA] sent QI2, IPsec SA established
Wed, 2007-07-25 10:24:27 - [USA] received Delete SA payload: deleting IPSEC State #11417
Wed, 2007-07-25 10:24:29 - [USA] sent QI2, IPsec SA established
Wed, 2007-07-25 10:24:30 - [USA] received Delete SA payload: deleting IPSEC State #11418
Wed, 2007-07-25 10:25:14 - [USA] sent QI2, IPsec SA established
Wed, 2007-07-25 10:25:14 - [USA] received Delete SA payload: deleting IPSEC State #11419
Wed, 2007-07-25 10:26:14 - [USA] sent QI2, IPsec SA established

However it does not log this for any of the other VPN's, and we have 3 others which are working just fine..

Any ideas on how to resolve this...

    Is your VPN setup to allow netbios between VPN endpoints?

    If you search for a remote computer using the IP address, can you find it. If you are able to find, then can you access the shared resources.

    As you have site-to-site VPN tunnel, by defaul all traffic is allowed on the VPN tunnel. Can you check if this is the case.

    Thank you.

    Changed the router and the problem went away. Netbios was enabled, and I couldnt access via IP either.

    It seems to be likely that NETBIOS traffic wasnt getting through, why I dont know as it had previously worked, but we needed to change the router for other reasons so this helped justify it.
