NWBC 3.0 connection thru saprouter outside LAN

hello guys,

someone of you tried to use NWBC 3.0 with the entry in saplogon with saprouter ?

I would like to logon to my NWBC outside LAN but the page does not come up . I have used the entry in saplogon that has public Ip of my saprouter .

The connection to my system works but the page of NWBC that uses this entry does not .

it seems like it's ignoring this entry

Any successfull case of using this scenario?

Regards
