Had a BM server which had a leased line to internet with ip of class C
210.x.x.x. Normal internet surfing had no problem and even had users able
to access back to company accessing Groupwise either online mode or remote
mode. Recently the ISP is providing Broadband users with Class A ip address
60.x.x.x. Now the weird part is that whenever users that are on this Class
A network, they cannot access the Groupwise server via any mode. Best part
is that users can ping to the server public ip address but not able to
access the application. Had remove all the filtering on BM but it didn't help.

Had check with the ISP and they told us that there is nothing wrong with
their end. What they said is that the BM is the cause of the problem as the
BM is preventing the Class A ip from getting into the network.
