Linksys VPN Tunnel Only Opens Shares One Way

Hello All,

    I have a client who is using the Linksys VPN Router RV042 at two separate locations.  They have setup a VPN Tunnel connecting the two routers at each location.  Currently I can ping computers via IP address at either location so it appears to be talking back and forth.  I can also open either of the routers by IP address when the Tunnel is connected.  The issue I have is that currently I can only open shares when connecting from Site A and opening computer shares on Site B.  But when using computers at Site B I can't open computer shares on systems at Site A.  Does it matter what side I initiate the VPN Tunnel from?  According to the user it was working fine for a while but just stopped working.  I noticed the Tunnel was disconnected so just enabled it again but can't get Site B to open the Shares located at Site A.

After the tunnel was re-established, can you still ping from Site B to Site A?  

When you try to access the shares, attempt it using the IP address of the host instead of the PC name to eliminate any resolution issues.   i.e. \\192.168.1.1\share      If it works with the IP but not with the name, you should concentrate on DNS or WINS issues.  

Are both sides using DHCP or static addresses?   If its DHCP and you are using active directory DNS, make sure DNS is healthy and replicating to and from each site.

Yes I can ping Site B to Site A.  I can ping the systems where the shares are located.

When trying to open the shares I have tried via \\192.168.2.100\share but I get an error saying it can't locate the resource.

Both sides are getting DHCP addresses from the Linksys routers.  This is a Workgroup environment.

Are the RVOs doing any firewalling between sites?  If so, what are you blocking ....   Are the windows firewalls active on the server or your local machine?

Try running the NET VIEW \\<servername>  of the machine you want to access.    Do you get an error 6118 back?
