My name is Diego and I am part of the Small business Support community. I have seen your post and would like to help you with information that might be helpful on your case. On the next link you would find an example of VPN tunnel configuration, step by step. You could find this and more information about our cisco small business products on the guide me section.
I check the link, and is great to get started on VPN
Actually I have a couple VPN set in my RV042 Router and they work fine
My problem is matching and pairing the RV110W with RV042, to make the VPN Tunnel working between this two aplicances, specially because the configuration available in the RV110W is very limited. and the configuration setup page is very different from the RV042
