VPN VNC and Web Services in router sub-network without Port Forwarding
Posted on 2010-08-25
Is there a way to accomplish the following without port forwarding? Here are details:
Looking for 1) VNC access and 2) access to web services, both hosted on the same PC within subnetworks.
There are several identically configured sub-networks for which this needs to be accomplished. Each sub-network is in a different location (i.e. time zones apart, different facilities) and behind a different gateway with the only known being that regular outgoing connections (email, Internet) are allowed as per typical PC usage behind the gateways. Each sub-network is behind its own identical router that I've configured. This sub-network router is what gets placed in the facility network.
[Remote Admin PC 0 VNC Client and Web Service queries] <=> [Internet Cloud] <=> [Facility 1 Gateway - No Port Forwarding allowed] <=> [My Router 1, Custom Config] <=> [My Sub-Network, including MS IIS running my custom Web Services PC 1]
Can you please clarify or suggest: if using VPN, can these (VNC, Web service query) needs be met without port forwarding?
I've seen references to Hamachi and hardware VPN as well as MS (Microsoft) VPN. Could you please provide notes about pricing of hardware VPN that might be affordable (under $200) per unit that could make that usable? Would simply running VPN on the PC 1 via Microsoft be sufficient?
Would VPN be required at the facility level, or could it just be implemented with my sub-network and then my remote admin PC 0? Perhaps just with required pass-through at the facility level (what would be required)?
If VPN would work, to what would I point my browser if I wanted to pull up the web service within the sub-network from my remote admin PC 0?
Please do not hesitate to post any questions at all if I need to clarify something here.
Thanks very much for your assistance.
