I have followed DrayTek LAN-to-LAN IPsec VPN Configuration Guide with my setup and i now have a green ipsec tunnel in VPN and Remote Access >> Connection Management but i cannot access any devices in the remote site.

I used this guide to get a connection.

My main site is on 192.168.1. range and my remote site is on a 192.168.0. range once connected should i be able to simply browse to each other in either web browser or explorer?

and also once connected should you be able to browse in both directions? from remote site back to the main site?

Thanks

In the first instance see if you can ping remote devices.

Tried to ping a known device on the other network with no response.

Okay, so if the tunnel us up, it's a routing issue of some kind. The networks/routers either don't know
how to route to each other or the router for replies. Double check VPN profile
settings, masks etc.
