Support is already on this, but perhaps someone has been through this before me. I'm running the Ros v4.17.
When I restore my configuration, and the router comes online, I can ping its WAN-ip just fine (I'm pinging it from a workstation to which I connect using Radmin).
All of the sudden it stops replying to ping (in less than 10 minutes usually). Firing some ports scans via the "shields up website" seems to expedite the issue. Instead of getting echo replies, I'm getting "destination host unreachable messages".
Rebooting the router does not help at all. Sometimes it evens hangs during a reboot and I need to cut power.
The only thing that helps is restoring the configuration again.
In the meanwhile I can browse the internet just fine. Everything else appears to be perfectly normal.
Pretty darn weird if you ask me:). Does anyone have any ideas what might be causing this stuff?
