proxy-arp & mpd

[Oleksandr Samoylyk]

Dear Community,

I'm using proxy-arp for public ips for our clients in order to give them 
internet access using pptp-tunnels with mpd:

# cat /usr/local/etc/mpd5/mpd.conf | grep arp
         set iface enable proxy-arp

# uname -a
FreeBSD xxx.xxxxxx.xxx 7.0-STABLE FreeBSD 7.0-STABLE #0: Tue May 13 
06:54:41 EEST 2008     root at xxx.xxxxxx.xxx:/usr/obj/usr/src/sys/XXX  amd64

Sometimes I see hanged arps:

root   72148  0.0  0.0  2564   788  ??  S     9:33PM   0:20.69 
/usr/sbin/arp -S xx.xxx.xxx.xx 0:e:c:70:c6:4c pub

where xx.xxx.xxx.xx is public ip address

In such moments clients can't connect to pptp-server (e.g., Error 800 
for Windowz clients).

Why does that happen? How can I prevent such situations?


Thank you!
