If your lag interface is up, what’s not working?

Does something like this work?

ping -D -s 8972 <ip L2 adjacent host>


and then this not?

ping -D -s 8972 <gateway>



If your firewall is on the LAN side supporting jumbo frames ok, but not WAN side, then the router will have to fragment all of the packets. (unless DF bit is set of course).
