Hi,

Natively, F5 don't allow to limit ssh connection. you can act on the following point:

expert@(appliance-name)(cfg-sync In Sync)(Active)(/Common)(tmos) list sys sshd all-properties
sys sshd {
    allow { ALL }
    banner disabled
    banner-text none
    description none
    fips-cipher-version 0
    inactivity-timeout 0
    include none
    log-level info
    login enabled
    port 22
}

You can restrict access to specific IP but don't limit connection number...
