I have a 2860 to 2760 with lan to lan vpn, which is working and connected.
However I can only access the router in the remote site not the nodes.
Yet the remote site can access the router and nodes on the main site.
The same happens when I ping or traceroute.

As far as I can tell bother are setup correctly.

Any thoughts anyone?

Is the 2760 (the remote site?) operating as the gateway on the network?

If the VPN is up but not passing traffic, there are two things that typically cause it:
1. The VPN router is not the gateway - in which case, set up a static route on the actual gateway to use the VPN router's IP for that subnet
2. Windows Firewall / other software firewalls - in which case, add the IP range of the VPN into the allowed addresses

There are some other things maybe to check? Have a look at this guide to confirm the settings match up
