Hi all!
I have a problem with sstp, which is working between two cloud core routers: CCR 1016 and CCR1036. Each routers has a static address on a WAN interface. Connection establishing by using certificates (key size - 1024), is working good and up less 1 second. Average latency in the tunnel is about 2-6ms.
Tunnel using to routing between our offices for sharing public folders and grant access to something servers. Network addresses and connection schema are in the attachment. When users working with RDP connection or using IP phones, everything is working good, average load to tunnel at that moment, is 1-2mbit, but when someone starts downloading something, ping in the tunnel increase to 150-300ms and usually stops.
I tested tunnel bandwidth with IPerf and got a bad surprise that I was right, tunnel does not working more then 10-15 seconds. When tunnel works with bandwidth more than 20mbit, usually it freezes, any data can't be sent, but the tunnel still works and switch shows the tunnels status, as "running". Thus, each time I have to restart connection manually or wait when it will be restarted by keep alive timeout.
(P.s. If you want and need it, I can make more screenshots and excuse me for my English)
With sincerely
