System Management Software 1 SEL Fullness on ESXi host.

Unable to reset sensors, unable to delete log from Vsphere Client/Web

You get these messages:

Solution for me was:

This is NO downtime, but it will disconnect from VirtualCenter for a short period of time. But it will reconnect.

ssh to esxi host

  1. localcli hardware ipmi sel clear
  2. /etc/init.d/sfcbd-watchdog restart
  3. restart

Referesh the Webclient.

All erros are gone.

Client VPN and VPN server in ASUS router at the same time. Route all traffic thru VPN service.

What we want:



I don’t think this will work with ASUS orginal firmware, I have not tested.
I use Merlin (

Check what TUN you have in the router via ssh
Command: route

Then you see what TUN you have on the vpn, in my case tun15
You can also use tun1+ but then all TUN will be affected

iptables -I POSTROUTING -t nat -s $(nvram get vpn_server1_sn)/24 -o tun15 -j MASQUERADE

Test if this works

Then add it to a script that will apply this automatic after renoot.

1. Enable script in the gui
2. Create script

vi /jffs/scripts/firewall-start

iptables -I POSTROUTING -t nat -s $(nvram get vpn_server1_sn)/24 -o tun15 -j MASQUERADE

chmod +x /jffs/scripts/firewall-start


Don’t forget to tick to start vpn client on boot in the gui


Redirect Internet traffic Any or selective routing
