Need to Load balance SFTP traffic

Hi All,

 

 

I need to load balance the SFTP traffic to two real servers. Can any one help me out please. The situation is exactly like this VS:192.168.10.1 :22 ----> RS1: 10.10.10.1:22, RS2 : 10.10.10.2:22.

 

I think it is pretty simple any help is higly apprecieated.

  • Here's a very basic walkthrough;

     

     

    Local Traffic > Nodes > Create -- Create two Nodes for your real servers, apply an ICMP Health Monitor

     

     

    Local Traffic > Pools > Create -- Create a pool and assign your two Nodes to it, specify the relevant port your real servers are listening on and apply a tcp_half_open Health Monitor

     

     

    Local Traffic > Virtual Servers > Create -- Create a Virtual Server, assign a name, IP address (that's reachable by clients) and relevant Service Port, Type: Performance (Layer 4)

  • Hi ,

     

     

    Thanks for help But I am still confused what persistence shall I use, I don't want to use Source address persistence as all the traffic is coming for Firewall IP so in this case if SA persistence is used traffic will end up going to single server, what can be the alternative , is HASH persistence can work for this ?
  • Hash persistence will not work as the traffic is encrypted. If my understanding of SFTP is correct, you do not need persistence. SFTP will use a single long-lived (if necessary) connection and not open additional ones like a HTTP client might.
