I have an SBS 2008 Server running DNS, DHCP etc on the range 192.168.42.x (where SBS is 239), Draytek 2930 is 1 (gateway). This is connected to fixed IP fibre connection (79 down,19 up). This is in Manchester.
A Remote office is setup using another Draytek 2930 connected to fixed IP ADSL (16 down, 1.2 up) using IP range 192.168.1.x where router is on 1 (as gateway) and DHCP is server via router. This is in Sheffield.
The remote office accesses a 2008 Server box physically sat next to SBS box on 42.71 for Terminal Services.
Trying to ping the names from of the servers from Sheffield - I get the response 192.168.56.1 for SBSSVR (SBS server) and no response for 2008SVR however RDP can connect perfectly for the IP.
The system works from the end user point but I do not know enough about IP addresses and subnets, or VPNs, to understand why it works or how to make it work with name resolution.
My questions are:
1. Why is the workstation in Sheffield (IP Address 192.168.1.102, Subnet 255.255.255.0 Gateway 192.168.1.1 Primary DNS 192.168.42.239, WINS 192.168.42.239) unable to resolve correctly the names located in Manchester?
2. How can I set it up such that all network traffic which does not involve the 42.x range is dealt with in Sheffield and does not impact on Manchester?
3. Would it be possible to add a Wireless Access Point into Sheffield to allow internet access which does not impact on Manchester at all?
Thanks for getting this far!
