CentOS 7.3 - Multiple NIC problems

[Grex]

Hi,

I have a virtual Server CentOS 7.3.1611 with kernel 3.10.0-514.26.2.el7.x86_64 on a ESXi 6.5 and have two network adapters (vmxnet3) added.

Code: Select all

        inet 192.168.100.70  netmask 255.255.255.0  broadcast 192.168.100.255

My gateway (Barraucda F600) has multiple IP addresses configured, one is 192.168.100.1 and the other 192.168.113.1, and has the same MAC address.
ARP table on client:
gateway ether 00:10:f3:5e:7f:6b C ens160
gateway ether 00:10:f3:5e:7f:6b C ens192


So the problem is, if I try a ping 192.168.100.1 I have 0% packet loss, but if i try to ping 192.168.113.1 I have 4-10 pings in a row of success, than I have a long timeout, that some pings are succesfully again. I have a packet loss of ~75% percent.

I temporary removed GATEWAY entry of ens192 and restarted network and adapters (ifdown && ifup) but it is the same problem.
