Our company has an MPLS VPN that connects the main site (lets call it A) and a branch office (B). Before buying the Peplink for B, the local computers on B were connected to the VPN through a Thomson TG585v8 gateway provided by the ISP hosting the VPN. The company decided to buy a multi-wan router for Office B which would host the VPN line and 2 more ADSL lines for internet use. The setup looks something like this:
Office A LAN —> Gateway —> ISP Backbone —> Thomson TG585 Gateway (provided by the ISP) —> Peplink Balance 30 —> Office B LAN
Computers in Office B are using a CRM and an Ordering application which run via a Remote Desktop connection (RDP) from office A (don’t ask me why…). When running the RDP from B to connect to A, print jobs from the ordering application must be sent to the main printer of Office B which is attached to the Domain Controller of B.
Our problem is that since Office B is now behind a NAT, Office A cannot see B’s LAN, thus the printer cannot be shared to the remote location. In other words, the printer from Office B needs to be shared to Office A. How can this be done?
How about if I NAT map the domain controller’s (i.e. the computer where the USB printer is located) IP to the WAN1 interface IP (OR the gateway’s public IP?), so then I could share the printer to the remote location using the Interface IP (or GW’s public IP) instead of the domain controller’s local IP.
Is this the way to do it? If yes, is it as simple as just mapping the GW’s public IP to the said private IP? Any other suggestions?
Thanks in advance,
