Hi all.
I access to internet through VPN/PPTP server.
Recently I tried to switch to another ISP
and have some troubles with it.

Minimal subset of my config look like this:

%%%%%%%%%%% /etc/ppp/peers/provider2:
debug
name cheusov
pty "/usr/pkg/sbin/pptp 217.21.51.32 --nolaunchpppd"
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

After '/usr/sbin/pppd provider2'
I have the following outputn from 'ifconfig -a'

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
ppp0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500
        inet6 fe80::2e0:4cff:fe14:2ed1%ppp0 ->  prefixlen 64 scopeid 0x3
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

and the following /var/log/message

What does the following line mean and how to fix this?
Jul  8 00:32:02 chen pppd[6708]: Couldn't set interface address: Address 87.252.248.124 already exists

pptp-1.7.0 is from pkgsrc.
