Hi: long-time WFH network+systems monitoring specialist, using multiple concurrent RDP+SSH sessions. Have had occasional, intermittent RDP session freezes (and reconnection), but since TT upgraded firmware in Sagemcom FAST 5364 to SG4K10002829t have experienced frequent RDP freezes - usually after resuming usage of a session - almost as though a device in the chain has quietly dropped the session, so next few packets go nowhere. Have attempted to prove this with simultaneous Wireshark sessions at each end - but can't see evidence of new TLS session and RDP uses UDP. Almost every RDP session (on 2 different machines) does this now after a few mins of not being used - exasperating and a major productivity hamper.
However, continuous ICMP Ping from my machine to RDP and google.co.uk *has* shown 3-4 dropped packets to RDP but *not* to google, suggesting that the VPN session is being hampered.
When TT firmware first upgraded, TT did acknowledge some VPN clients had been affected by f/w upgrade: wondering if this issue is still there? Typically running 6-8RDP sessions + 2-5SSH sessions at once, as well as non-tunnelled mail/web/StackOverflow (!) web sessions.
Any ideas? Seen this elsewhere? Thanks.
