I have a TS-X8.0TL/R5 NAS on each side of our site to site VPN connection. Machines on the other side of the connection can see the local NAS, but I can't from my side. I can remote into the windows PC's on the other side of the connection and can ping it and use its URL to access it. Two ASA5505's do the site to site VPN duty. On my side of the network the subnet is 10.2.3.X and gateway 10.2.3.2 on the other side is 10.2.5.x and 10.2.5.1. Both sides use DNS servers 10.2.3.11 and 10.2.3.13. I noticed that the NAS devices on both sides of the network don't show up in DNS. We always contact them via IP address. Any help would be appreciated. Router configs available if needed.
