We have same problems with 109/8 (allocated to RIPE NCC on January 2009)

When got report about unreachable network/server/(or only one service),
we must find and contact administrator of this network/server and ask 
him to repair firewall.
(Sometimes we must tediously explain, that problem is at their side)

I wish you luck
