NW6 sp3 / BM 3.7 sp?

We have our Groupwise server on the private network. A public IP is
bound to the public NIC on BM. Outside access to GW is fine using the

DNS name.

When accessing GW from the private LAN, DNS name fails. We understand
is a BM thing. We set up a DNS server to alleve this but it is not

I was hoping there is a solution on the BM side of things to allow the

DNS name to get to GW server when the request originates from the
private LAN.

Currently, staff are required to use an IP addr when in the bldg, and

the DNS name when at home.

Any input is appreciated
