We have Azure Load Balancer which needs to be redirect traffic any of the Healthy IPTABLE Servers (Total 2 IPTABLE Servers). From IPTABLE server traffic will be forwarded to Other Production Servers (Which are not accessible Directly).
We have configured port 22 as health probe on Azure Load Balancer. Because of this we are getting logs created like following on Production Servers.
2019-04-27T05:52:29.443677-05:00 azneqodrt001 sshd: Did not receive identification string from 10.16.10.12
Alternatively, We have created custom port 5500 using nc command. Again we have reconfigured Load Balancer health probe with port 5500 (on IPTABLE Servers) instead of 22. But it was worked only for few minutes. Later it stopped working.
Can anyone suggest any alternative for this kind of situation.
