At one of our destinations we have problems with UDP packet loss and therefore the Speedfusion VPN is very slow. IPSec VPN works better but I cannot figure out how site A, B and C which are connected over MPLS can communicate with each other.
Below you see the network diagram. The company policy doesn’t allow local Internet breakout so all traffic goes via VPN to HQ (the IPSec VPN Profile the remote network is 0.0.0.0). I would expect that local network still can communicate with each other as there are static routes to each subnet but it seems that IPSec VPN overules the static routes. With SpeedFusion/PepVPN it worked fine.
