Exchange iApp and app service name with dots

Hi!

I deployed Exchange iApp v1.5.1 and used our FQDN as App service name, and ran into an issue with the generated snatpool irule.

When connecting to the VIP this error message is logged

TCL error: /Exchange/mail.domain.com_Internal.app/mail.domain.com_Internal_snatpool_irule3
 - can't read "static::snat_ips_domain": no such variable     while executing
"snat $static::snat_ips_mail.domain.com_Internal([expr {[crc32 [IP::client_addr]] % [array size static::snat_ips_mail.domain.com_Internal]}])"

The generated iRule looks like this

when RULE_INIT {
     Use a local array to configure SNAT addresses.
     These addresses do not need to be defined in a SNAT pool or elsewhere.
    set static::snat_ips_mail.domain.com_Internal(0) 10.10.1.151
    set static::snat_ips_mail.domain.com_Internal(1) 10.10.1.152
    set static::snat_ips_mail.domain.com_Internal(2) 10.10.1.153
}
when CLIENT_ACCEPTED {
     Calculate the crc32 checksum of the client IP
     Use the modulo of the checksum and number of SNAT IPs to pick a SNAT IP
    snat $static::snat_ips_mail.domain.com_Internal([expr {[crc32 [IP::client_addr]] % [array size static::snat_ips_mail.domain.com_Internal]}])
}

Just from reading the error it looks like the reference to $static::snat_ips_mail.domain.com_Internal "breaks" after the first dot.

I've tried enclosing the array name in curly braces in different ways but that only produces various syntax errors.

TCL and arrays are not quite what I do every day 🙂 Is there any way to modify the snat statement so that it can reference static::snat_ips_mail.domain.com_Internal?

Thanks
