To be sure you'll need to check the MTU end to end from client to F5, something in the path may have a lower MTU.

 

Note MTU size on the F5 does excludes Ethernet headers so a value of 1500 should be fine (rather than 1518).

 

If you really want a larger MTU and want ICMP to work with it, let me know and I can supply the db key you need and save you a call.
