L4 ace30 - ssh and sftp fail

Hello , Team

The XXX.XXX.2.XXX bandwith is divided into 1-127 and 128-254.

A server ip - XXX.XXX.2.139.

The B server has two IPs. (one- VIP:XXX.XXX.2.32 , Real IP-XXX.XXX.2.141)

-A server can connect ssh and sftp to B server Real IP.

-Within the local L4 configuration, the other bandwith servers are ssh and sftp connections to the B server VIP.

 

issue : Ping from A server to B server VIP goes out.

However, ssh and sftp connections can not be made from A server to B server VIP. This is not enough.

( A -> B VIP ssh and sftp access fail message)

Connecting to XXX.XXX.2.32 . . .

ssh : connect to host XXX.XXX.2.32 port 22 : Connection refused

Couldn`t read packet : Connection reset by peer 

 

I knew. When the A server tries to connect ssh and sftp with VIP IP, the destination real Real ip responds.

Therefore, ssh and sftp connections fail in the same ip band (10.2.227.139 -> 10.2.227.141).

 

To solve this issue, do I need to set something like SNAT or proxy ip? Or are there other solutions?

 

Best Regards.
