Two separate floating IP's is fine from an LTM POV... However GTM really wants to be configured on a non-floating IP. I've never tried configuring a GTM listener on a floating IP before... That may be where you strike any issues.Even if it works straight away, I've had strange behaviours in the past from GTM when bending the rules slightly.

 

If you do get it configured like that. Make sure you check out the sync between any other GTM's you have configured (The above GTM Primary/Secondary implies your'e running two GTM's in a sync'ed config). That's probably where it will go bad if it does.

 

What I'd suggest though is configuring TWO separate NON-floating IP's per GTM and creating GTM listeners on those. (For a total of 4 separate GTM listeners)
