Thank you so much Thomas, some progress, it works!
Sorry I bother to a few more question:
Testing a bit I sudden see "neighbor sol" message come from ::2 instead of ::1,
and traffic no longer work. They use two gateway? I add both?
If you write ::2, are you referring to 2a03:118e:202::2 or
2a03:118e:202:55::2?
Neighbour solicitations are used by nodes to find other nodes, not routers:
https://en.wikipedia.org/wiki/Neighbor_Discovery_Protocol#Functions
And How I can use specific octets for my address? I test to use ex. "::123" making my address
"2a03:118e:202:55::123" instead of "2a03:118e:202:55::" but then it doesn't work at all.
Are you sure the complete 2a03:118e:202::/64 prefix is routed to your
server? Or do you only get one IPv6 address out of /64 prefix?
If the /64 prefix is indeed routed to your server then you can add
another IPv6 to your interface and that will work.
ifconfig vio0 inet6 ....::123 alias
https://man.openbsd.org/ifconfig#alias
Btw - slaacd: you can stop & disable slaacd if you get a link local
default route which doesn't work. RAs is a normal way to get a default
route but providers may handle it differently.

You have to add the gateway first, an example can be found in the
route(8) manpage: https://man.openbsd.org/route#EXAMPLES :
"Add a static inet6(4) route to a host which is on the vio0 interface
that is outside your prefix, and use that host as a default gateway, as
used by some hosting providers:
# route add -inet6 2001:db8:efef::1 -cloning -link -iface vio0
# route add -inet6 default 2001:db8:efef::1"
