connecting 192.168.1 to 192.168.2

Question

_{Monday, January 14, 2013 2:08 AM}

We have two locations with small networks. One is defined as 192.168.1... and the
other as 192.168.2... There is a vpn defined between the two locations using ipcop
firewall/routing software at both locations. The vpn allows access to the erp
located at the 192.168.1... location. There is a MS 2003 SBS server at the 192.168.1... location
which I want 192.168.2... to have access for exchange email using outlook. They cannot see server.
I opened port 25 for the server but they cannot see or ping the server dns name. How can I
make this happen? I would like for 192.18.2... to have all resources at 192.168.1... if that
helps with your suggestion.

Thanks

  The first thing to work out is whether the VPN is correctly set up. If it is properly configured as a site to site VPN, any machine should be able to contact any machine in the "other" site.

  If the routing is correct, the next problem is DNS. Routing just provides IP connectivity (ie by IP address). To access a machine by name requires name resolution. Access to domain resources may also require domain membership (or at least a valid account in the AD database for the requester).

Hi jp501428,

Firstly, please check if you can ping each other with IP address.

If pinging is successfully, please let us know how you configure the DNS Server.

Based on my understanding, if you have a DNS Server in each site, you need to configure Zone Transfer correctly. If you have only one DNS Server, please make sure that you have pointed all your clients to it and please verify the DNS records.

If issue persists, please provide us unedited ipconfig /all of clients from each site for further research.

Hope this helps.
