Hi, we have a MediaFast 500 on our main site and a consumer Router in 2nd office at another location. We’ve set up “remote user access” via L2TP with IPsec on our MF500 so users can connect via VPN in order to access a SambaShare on our MainSite. This works quite well when everyone is in a different location.
However, when two employees are in the second office (so the two employees share the same network), and try to establish a VPN connection to the main site, only one can connect at the same time. The second one can’t establish a connection until the 1st disconnects. This seems to only happen with Windows Clients. Macs seem not to be affected by this.
I’ve done some research on the web and found that we’re not the only one with this problem. It seems like a limitation in IPsec itself and a design choice in how Windows establishes L2TP IPsec connections. However, it seems that technically it is possible. I’d like to know if we can find a way to debug this / get around this.
