Hi,
I am having a strange issue. For several years we are using several networks connected through VPN site-to-site tunnels, using Cisco ASA appliances. I am in the central office, we have a Windows 2008R2 server and people can remotely connect into it from local net, over the site-to-site VPN or over a personal tunnel created with AnyConnect. On one remote site ( Taiwan) we have another Windows 2008R2 server installed long ago that can be access from anywhere. All servers are inside, none in DMZ. Recently they installed a 2012 server in the Taiwan office. It can be accesses ( ping, RD) from the local net or from a tunnel opened with AnyConnect. But I cannot access it over the site-to-site tunnel! Not even the ping.
I have no experience with 2012 servers and ... it is installed with Chinese interface that I cannot read anyway. I was thinking the Windows firewall was preventing the connection, but the local admin told me he turned it off.
Any idea where to look for? The only difference between accessing the firewall over the site-to-site VPN and locally or client based VPN is the IP address, the server net is 10.30.10.0/24, client VPN is getting 10.30.254.0/24 and the computers over the site-to-site VPN are using 10.10.0.0/16 addresses.
Thanks for any advice
