Userland PPP not deleting old IP on disconnect

Hi Fellow Node user :),

I have the same + similar issue.

tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1492
         inet 121.45.215.128 --> 203.16.215.183 netmask 0xffffffff
         inet 121.45.69.26 --> 203.16.215.186 netmask 0xffffffff

The second line only shows up when the gateway is different between IP 
assignments from the ISP. I have no idea if this blocks access to the 
previous IP, not that it's a major issue.

uname -a
FreeBSD gateway.abdulla 7.0-STABLE FreeBSD 7.0-STABLE #1: Sat Jun 21 
03:10:37 CST 2008     root at gateway.abdulla:/usr/obj/usr/src/sys/MYKERN  i386

My ppp setup is almost the same.

Cheers
