iRule to allow IP exceptions for starttls required SMTP

Hello,

 

I'm trying to write an iRule for one of our clients. They require STARTTLS on SMTP for all clients except for a select few IPs. Is there a way to write an iRule to allow these IPs to bypass the STARTTLS require tag I've added to the farm?

 

Thanks,

Kj

    Id try putting a dgl for exceptions and calling that in client accepted event to bypass those. Try modifying and​ test it. Good luck.
