Number of interfaces: maximum 3, was unlimited.
Currently (FortiOS 7.2.1), though, there is no actual enforcement of this limit - I configured BGP and few static routes, 6 all in all, and it worked without any issue. This means severe limiting of dynamic protocols labs like OSPF/BGP. Number of routes: the limit is also 3, while was unlimited before. Security Rules: the limit is 3, instead of 5.
