RV215W - Problem setting up site-to-site VPN

Question

Hello,
I've taken a plane to newbie-land and need help in setting up a site-to-site VPN. I know this is very basic stuff so I apologize for asking something that's been answered a million times before. I just can't find an answer I can translate directly to my situation.
I have two RV215W routers, and although I've found a considerable amount of information on setting up the VPN on this model, I can't find anything on setting up two of them to create a functional VPN. I think I'm probably making an error in my IP addressing.
It appears that somehow I'm creating an endless loop on at least one end.  I can't ping specific devices on the other network, and when I type the LAN IP address of the remote router into a browser it actually goes to the local router's setup page. After running awhile the network gets so bogged down with its own traffic (I'm assuming) that it grinds nearly to a halt. I can see in the IPSec connection status that both sides are connected, but I'm not sure exactly what they think they are connected to. Tons of VPN traffic on both ends, though.
I have been using the Basic VPN Setup page  following instructions in the RV215W Administration guide's "Configuring Basic Site-to-site IPsec VPN Settings", page 104. Basically, I'm configuring the routers as mirror images with regard to local and remote LAN and WAN settings, although I have to admit I don't know if that's how you're supposed to configure them to work together.
Here's my environment:
Local Network:
WAN: XXX.XX.XX.XX
LAN: 192.168.0.0/255.255.255.0
Router IP Address: 192.168.0.1
Remote Network:
WAN: YYY.YY.YY.YY
LAN: 192.168.1.0/255.255.255.0
Router IP Address: 192.168.1.1
Here are my router configurations:
Local Network Router:
Connection Name: Bob
Pre-shared Key: wxyz
Remote endpoint: 192.168.1.1
Remote WAN IP Address: YYY.YY.YY.YY
Redundancy Endpoint: Not enabled
Remote LAN IP Address: 192.168.1.0
Local LAN IP Address: 192.168.0.0
Local LAN Subnet Mask: 255.255.255.0
Remote Network Router:
Connection Name: Jerry
Pre-shared Key: wxyz
Remote endpoint: 192.168.0.1
Remote WAN IP Address: XXX.XX.XX.XX
Redundancy Endpoint: Not enabled
Remote LAN IP Address: 192.168.0.0
Local LAN IP Address: 192.168.0.0
Local LAN Subnet Mask: 255.255.255.0
When I look at the advanced settings I don't see any items that need to be changed, at least according to what I've gathered in my searches for information on my problem. The IKE and VPN policy tables are enabled, and for kicks I've toggled NAT traversal and NETBIOS different ways.
Thank you for any help!

Answer 1

We are a relatively small not-for-profit so I've never had to do much in the way of anything beyond setting up stand-alone networks and no-brainer stuff like port-forwards, troubleshooting devices that don't like this or that feature in a router, etc. We are growing quickly though.
The reason I need to do this one on-site is because there are several devices I can't reach remotely. They have specific IP addresses and you can only configure them from the front panel. Nearly everything else would work perfectly, but those devices would not be happy. :-) I'll be able to remote from there though to a computer at this location.
Thanks again!
