I don't know if this is the right forum to ask about BBSM, but maybe someone has had these problems.
The first problem is the BBSM box seems to only redirect page sets located in the /ekgnkm directory.
The second problem is that we have to map a port before anything else, and since the client isn't able to access the /welcome.asp directory we are not able to map the port.
We have tried the walled garden, and that didn't help. We think the problems are related because the (unauthenticated) client box won't access or be redirected to anything accept that ekgnkm directory.
If anyone has any ideas or suggestions they would be greatly appreciated.
