CISCO ASA 5505 - Port forward problem
HejHåber der er en der kan hjælpe her da vores CISCO er ved, at give mig grå hår og det der er værre :-)
Først lidt baggrund info for at forstå problemet:
Offentlig statisk IP adresse på CISCO'en: 87.61.46.250
LAN 192.168.29.0 / 255.255.255.0
Der er desuden en VPN tunnel til 87.237.152.33 som virker :-)
Jeg har en test server med statisk IP 192.168.29.200 på LAN'et hvor der er en server applikation der lytter på port 50000
Jeg kan ikke få hul igennem fra internettet og ind til denne applikation på trods af, at jeg mener at have lavet NAT og de rigtige access regler :-)
Her er configurationen:
