I have BM 3.8 on OES NetWare : private address mask

Some users need to reach proxy on (because they get proxy thru
zenworks policy and I cannot change it) from stations 192.168.101... mask thru GW

So I configure a static route on GW : host next hop BM routable

I've verify all filters on BM but stations can't access even if
I put it "private and public"
With pktscan I saw that packet arrive on the BM routable address but they
never be pass to the private.

If I down Border I can ping from station without problem.
If I restart Border I can't.

Does anybody can say me why ?
