When you enable mpd5 on Freebsd 9.1, the outgoing speed of the Internet connection on the VPN clients and server drops. Where to dig?

Set up Freebsd 9.1 vpn server on mpd5 (Version 5.6). There was a VPN server, everything was in order. The server was updated a very long time ago, because. performs only three functions, and there was no need to update. Recently I noticed a very fast drop in the speed of the Internet connection, with mpd5 enabled, both on the server and on clients that are connected via VPN. Turning off MPD5 - all the fire. Has anyone encountered a similar problem? Changed network cards to new ones - no result.
mpd.conf
#
# MPD configuration file
#
# This file defines the configuration for mpd: what the
# bundles are, what the links are in those bundles, how
# the interface should be configured, various PPP parameters,
#etc. It contains commands just as you would type them
# in at the console. Lines without padding are labels. Lines
# starting with a "#" are comments.

Tell me, where can I dig? Google has been working for a month, nothing sensible and specific on this problem was found.
Additional information is required - I will send it without problems.

Few initial data. Do clients go to the Internet through the same VPN server when connected?

Yes, clients use Internet VPN servers. There are essentially two clients, more is not required. What other data are you interested in?
