Been trying to concatenate sets update:

tcp dport @b_t update @b_sa4 { ip saddr } drop;
tcp dport @b_t update @b_sa6 { ip6 saddr } drop;

with:

tcp dport @b_t update @b_sa4 . @b_sa4 { ip saddr . ip6 saddr } drop;
What's the intention here?

but that did not work out. Is somehow possible to concatenate sets update?
Yes, you can do:

tcp dport @b_t update @b_sa4 { ip saddr . ip6 saddr } drop

You can update one single set at a time. Not sure what you expect from
this concatenating sets instead of keys.

The two mentioned sets are dynamic, learning ip | ip6 saddrs from hits on tcp dport.

The intended concatenation was to put it into one rule instead of two, like if ip saddr then update element in set @b_sa4 and if ip6 saddr then update element in set @b_sa6 respectively.
