Routing problems on VPN servers running FreeBSD 8.0-RELEASE

[Li, Qing]

Few of the symptoms you described here were present in the vanilla
8.0-RELEASE but I have been fixing these in 8-STABLE since the official
announcement.

Could you please try 8-STABLE and report back if these problems
persist there?
