freebsd security - Oct 2015 - VPN support broken after Freebsd 10.2-RELEASE p4 update (FreeBSD-SA-15:24.rpcbind)

Hi,

can anybody help me?

I have a linux VPN host in my network and a Freebsd host (FreeBSD 10.2-RELEASE):
after the latest update (p4) I'm not able to access my BSD system via VPN.

From inside my network (not using VPN) everything works fine; however FreeBSD
host is unreachable via VPN.

I can reach via VPN every other host in the network.

Any idea?

Regards
