Hello,
any month my Sophos UTM works fine, but then i get Errors to connect to WebUI (Error "503 Service unavailable".
So i install (download fresh latest ISO) it new on my ESXI 5.5 with the Informations i found for VMs: Suse Open Server 11 64 Bit Template, 2 CPUs with 2 Cores, 4 GB Ram, 100 GB HDD, 1 x VXNET3 Adapter, select Default Setting for HDD (i think it was LSI SAS Controller).
I create new virtual Harddisk (on a other physical Disk, then the VM before), cause i read in some other threads about 503 Problems that they has Hardwareproblems (e.g. SSD Firmwareproblem, HDD Bad Sectors).
The VM has only one NIC, cause i can not connect them between Internet and LAN (cause it is an Cableinternetconnection, and only works with my Fritzbox - but this is an other Problems).
So i have Defaultgateway (Fritzbox) 192.168.40.254, UTM (LAN) 192.168.40.250 and some Servers/Clients in the 192.168.40.0/24 Network.
in the first Step, the UTM makes only Emailprotection (NAT Port 25 from Fritzbox to UTM), the UTM filters and send to Server 192.168.40.2. This works very fine.
I can access without problems, to the WebUI - but some hours later, this doesn't work. I get Error "503 Service unavailable" - i restart only UTM and everything works fine for the next hours.
I have Home License, so the Support says, i have to went here for help.
Can anybody help me to fix this error?
