Hi Dobby,
I am using the router as an AP in holiday villas. The network setup has an RB951 in each villa configured as an AP with hotspot and external RADIUS authentication. The ether1-gateway is connected to an SXT-5HPnD on the roof (in bridge mode) linking back to an Omnitk on the roof of the villa that actually has the internet connection. This is in turn connected to an RB
751 which does the main routing. I am out and about at the moment so cannot do a network diagram or post configs but could do this later if it would help.
The key points of the network are:
- Hotspot configured on all RB951 and RB751
- External RADIUS authentication
- OVPN connection to central server 1 for DUDE monitoring
- PPTP connection to central server 2 for RADIUS
- Watchdog configured to ping management server
- Between 1 and 7 RB951s connected to each cluster
The issue that I am getting is that some of the RB951s will just hang and the DUDE will show them as down. Even after the Watchdog Ping time has expired they do not reboot and I have to go out to the villa to reboot them by cycling the power. When get to the villa there is no response from the box on either the wireless or wired ports so there is no way of finding out what is happening at the time.
The lookups can happen at any time and even when the villa has been unoccupied for over a week and there is no real traffic load at all. It is driving me nuts currently as I have around 40 951s installed and at least 1 or 2 lock up every week.
Any help or advice would be greatly appreciated.
Thanks
Steve
