Can somebody give me a basic overview of how to set up a site to site VPN.
OK VNP experience is a little lacking, I dial into my office on my PC using PPTP, Single PC, Single User, Simple to set up. OK now I need to bridge two LANS over a VPN - the important thing is that both the local and remote LAN are the same LAN.
My LAN at the office is on 10.1.2.0, all HOST’s on the network are assigned static IP addresses (Servers and equipment - and I like to know where things are). The router is connected to the internet via dual 1:1 Gbit fibres. I would like to extend part of the 10.1.2.0, say 16 (14 usable?) IP address, on to a remote LAN. The reason for this is we have some equipment that MUST sit on the same LAN, but we need them at separate physical locations. The branch office is fed with a single 1:1 Gbit fibre internet connection (It currently has a PFsense router - but that can change).
What type of VPN would be the best to use? Much of the content will be UDP audio and video streams, and latency is an issue.
What happens with broadcast and multicast traffic over the VPN. Whilst some of our software uses mDNS and ZeroConf, we can manually enter IP addresses if issue with broadcast address.
Can somebody give me a clue on the process of setting up the LOCAL and REMOTE routers, do I need security certificates? do I have to pay for them? do I then need a domain? the list goes on - this is not security sensitive or exciting data so don’t need to go overboard.
Thank You
