The hna 1.234.56.0/27 and 123.45.67.0/24 must be replace by the HNA you
need for your configuration.
Your problem is simple, Dev A have no default route because Dev B must
have the HNA 0.0.0/0 so all other olsr node send it all request not
destinated to your internal network (destinated to the external network
aka internet because it's the olsr node that know how to reach the
internet).
Dev B don't need any hna because it will automaticly declare himself as
a /32 so all other olsr node will know how to rech it. You only add hna
when your need to route a subnet of device not supporting olsr.
So erase all hna, add the hna "0.0.0.0 0.0.0.0" to dev b that all.
