problem:
after few minuts, sometimes hours
without any warning
and no log entries
router stops forwarding ports for LAN servers

only remote restart/reboot helps

:-(

I use virtual servers section to forward ports (web & ssh) into LAN servers
I also use VPN to manage my LAN

the same behaviour is with all protection against attack enabled and also with disabled


when router stops forwarding, I'm able to open vpn and manage router
I can't ping local LAN servers from router's Diagnostic panel


any ideas what is going on?
