so that iRule comes from the devcentral wiki entry on TCP::option, did you read that whole section?

it mentions changing your TCP profile with the tcp-option setting (seems CLI only), i got the same error until i created a second TCP profile like.

create ltm profile tcp tcp-opt-change tcp-options "{29 last}"

but are you sure this is going to do what you want? it suggests something like adding the client IP, but that option 29 seems not meant for that. it might be a typo and should say 28, but even if you do that it all depends on the receiving system understanding what you do and looking at that.
