Since last night I’m experiencing a strange connectivity problem. Before I continue to describe this problem, I’ll explain my new setup.
- 2 virtual machines
- 3GB Ram Each
- 40 GB Disk space
- 1 Intel virtualization
- 1 AMD virtualization
That’s it for the hardware part, now the software part
- Using a High Availability Cluster (Thank you for fixing this one)
- 3 Uplink interfaces to BGC (Belgian ISP)
- 1 Ethernet connection 192.168.1.x / 24, wireless access point
- 1 Ethernet connection 10.13.37.x / 24, internal
- 1 shared connection, 10.13.38.x / 24 internal DMZ
Problem:
This morning I noticed that my Astaro Appliance hadn’t had any problems with the kernel panic. (please look to the other thread for that). However, I did notice that 10.13.37.1 wasn’t ping able. I thought that the interface or the Astaro would be down. However, when I tried to ping 10.13.38.1 it worked.
Examples:
root@kwik-e-mart:/mnt/datastore0/scripts# ping 10.13.38.1
PING 10.13.38.1 (10.13.38.1) 56(84) bytes of data.
^C

But, looking at the ARP table, is see the address….

When I ping from another server…. It seems to be reachable. But there is no really connectivity except the ping command.

IPS is disabled so that should not be a problem. Any ideas?
