SNAT outbound connections from pool members to virtual server IP for a specific outbound port

Hi,

First, when creating a forwarding VS, create a specific VS for FTP:

VS_OUT_FTP

• Type Standard
• Destination 0.0.0.0/0
• profile ftp
• translate disable (default when creating a VS with a network destination)
• Pool none

This will allow FTP dynamic port to be handled as FTP Data connection.

After that, you can create the irule with switch instead of if, elseif, elseif, ..

when CLIENT_ACCEPTED {
    switch [IP::client_addr] {
        "10.0.0.10" -
        "10.0.0.11" { snat 172.18.1.1 }
        "10.0.0.12" -
        "10.0.0.13" { snat 172.18.1.2 }
        "10.0.0.14" -
        "10.0.0.15" { snat 172.18.1.3 }
    }
}
