I've noticed that I cannot maintain stable RDP or VPN sessions to my clients networks. They seem to drop every few minutes. ... been slow since they had that disaster 3-4 weeks ago?
I'm a VPN novice, but would guess at physical-layer disruptions, which might not be alerted by their web-browser. Karoo might clarify any line-events, unless they've System Maintenance/Error Logging turned-on for their Router/Modem and its Log's haven't a narrow time-span due to spurious data.
Tunnels created by Check-Point's VPN-1 client seem isolated from the Router's re-dialing, and their client seems even to ride-out new IP-Addresses + NAT, but the Citrix Presentation-Server Webclient crashes and can even leave remote Applications open.
After the 23-Jan crash, an automated message advised callers to turn their Routers OFF/ON. Needed to unhook both mains+DSL from mine, which was recursively dropping its line.
