There are a couple possible things to look at here. First, check the DRAC and the switch port it is attached to, and make sure it is set to Auto Negotiate the settings. I have seen some odd and intermittent behaviors when the DRAC or switch port is set to a specific speed, duplex, etc.
The second thing to try is remove the DRAC from the public IP and keep it on the internal LAN. I'd do this anyway because though the DRAC is not particularly hackable, nothing is completely impervious and giving somebody with bad intentions even 5 minutes in a DRAC can be disastrous. If you keep it on the LAN then you can use a VPN router or other remote access setup to get to a machine on the local network and then open a browser to get to the DRAC.
The switch port is set to Auto Negotiation as well.
Also, unfortunately there is no possibility to get private address, since its a co-location room, as I know, the ISP don't have this "feature", so they does not offer VPN ot any other solution which would allow me to set up private address.
The web server is turned off, ssh default port is moved from 22 and we have a "strong" password for the admin user. I think this is all I can do here.
I have an r710 and I had the same issue that I managed to solve by making sure that my ipv4 IP address's first three sets of numbers matched the network. I hope this helps you.

Hi Jeff,
Here is my related config parts:
/admin1-> racadm getconfig -g cfgNetTuning
cfgNetTuningNic100MB=1
cfgNetTuningNicFullDuplex=1

cfgNetTuningNicAutoneg=1
/admin1->
/admin1-> racadm getconfig -g cfgLanNetworking
cfgNicEnable=1
cfgNicIPv4Enable=1
cfgNicIpAddress=x.x.x.x
cfgNicNetmask=255.255.255.0
cfgNicGateway=z.z.z.z
cfgNicUseDhcp=0
# cfgNicMacAddress=d4:ae:52:80:8e:47
cfgNicVLanEnable=0
cfgNicVLanID=1
cfgNicVLanPriority=0

cfgDNSServer2=0.0.0.0
cfgDNSRacName=idrac-xxxxxxx
cfgDNSDomainName=
cfgDNSDomainNameFromDHCP=0
cfgDNSRegisterRac=0
/admin1->
The switch port is set to Auto Negotiation as well.
Also, unfortunately there is no possibility to get private address, since its a co-location room, as I know, the ISP don't have this "feature", so they does not offer VPN ot any other solution which would allow me to set up private address.
The web server is turned off, ssh default port is moved from 22 and we have a "strong" password for the admin user. I think this is all I can do here.
Do you think it is enough ?
Any other suggestion for the base issue ?
Thanks,
Misi
