I have a remote site that is very small that I want to set up a site to site VPN to be able to firewall the traffic at the remote site. After setting up the VPN, it seems that I cannot get any Netwerk to communicate from the main site to the remote site other than the LAN network. Also, I cannot reach any devices between the two networks unless it is on the LAN network.

Has anybody had experience with this? Here is a brief layout of my network:

Main site: WAN>ER605>Firewall(PA850)>Cisco switch>site servers/resources/AP's

Remote site: WAN>ER605>EAP>site devices

Trying to go from remote site devices>Remote site ER605>Main site ER605>PA850>WAN
