Re: RV082 and QuickVPN

Are you trying to use QuickVPN to connect from a home PC to your RV082 at work? If so, what's your home router's model?

Please ensure the ip address of QuickVPN client is not in the same subnet as the LAN IP of RV082. Otherwise the tunnel will not connect.

How is RV082 connected to the internet? Does RV082 see another firewall router in front of it?

Re: RV082 and QuickVPN

Hi Davide

     I don't know if you trying to tunnel or use the vpn client, but the vpn client does not allow netbios to pass thru so you will not see the shared printers and files. If you tunnel between 2 routers it should allow netbios to pass thru, but the quick vpn client does not. Regardless if you want to use tunneling between routers or using the Quick vpn client both ends need to be on separate subnets. I hope it helps.

Hi, zzorro2001

QuickVPn is only a VPN client
I did not know that you can not share directories and printers

If I want to connect a RV082 and see directory and printer share, what I use?
I want use from my home and with my notebook with wi-fi

Thanks!!! Davide

Re: RV082 and QuickVPN

Not sure the issue you are having but it sounds like the local ip address is the same as the local lan ip address of the remote vpn router.  They have to be on different subnets.  Example 192.168.1.1 on the remote connection, and 192.168.2.1 on the rv082.

With QuickVPN 1.2.6 on first PC 192.168.1.100 connect

With QuickVPN 1.2.11 on secondo PC 192.168.1.101 Nothing

Boh!

Thanks

Re: RV082 and QuickVPN

We do this day in and out here using the RV042.  It's a great router except QuickVPN doesn't work.  It never has.  Use the PPTP server and everything will work fine.

Re: RV082 and QuickVPN

Try changing the home local subnet to a 10.x.x.x network and see if you get the same error message.

Re: RV082 and QuickVPN

There is a bug in QuickVPN where it doesn't resolve subnets correctly.  I appears to me that it's looking a substrings to determine if the networks conflict instead of really looking at the subnet.  In your case, you have an endpoint lan subnet of 192.168.10.x/24 and a source subnet of 192.168.1.x/24.  The software is looking at your source subnet string as "192.168.1" and comparing it to the string "192.168.10".  Since your destination subnet string starts with the source subnet string then it fails.  It's really stupid. You can do change your source subnet to anything but 192.168.1, 192.168.10, and 192.168.100 or change your destination subnet to anything but 192.168.1, 192.168.1x, 192.168.1xx.  It's embarrassing that Linksys/Cisco has a lazy programmer that can't do a real subnet check.  Even more embarrassing that this bug has been in the software for years.

In my case, my home subnet was 192.168.1.x and I couldn't connect to 192.168.121.x.  If I changed my home subnet to 192.168.2.x it would work.  If I changed my home subnet to 192.168.12.x it would fail ("192.168.121" starts with "192.168.12").  If I changed my home subnet to 192.168.11.x it would work. Etc.

Re: RV082 and QuickVPN

Yes, it is a known issue with the quickvpn client and as the cisco partner replied the work around is to have the third octect start with something other than a 1 if the other client is using a 1 in the third octect.  I apologize for this inconvenience and Cisco is aware of this issue.
