Hi,
We've got a Cisco 851 router and we are hosting Web services (HTTP et HTTPS), email (SMTP) et VPN (PPTP, L2TP).
As we don't know Cisco CLI, I used the SDM to open ports.
I opened the Web, Mail and PPTP and they are working. But L2TP is not, user connexion are not working, the L2TP server is not receiving any request. Can you check my configuration.
IP Cisco : 192.168.0.254
Web, Mail, VPN : 192.168.0.253
Open Ports:
ip nat inside source list 1 interface Dialer0 overload
ip nat inside source static udp 192.168.0.253 4500 interface Dialer0 4500
ip nat inside source static udp 192.168.0.253 500 interface Dialer0 500
ip nat inside source static udp 192.168.0.253 1701 interface Dialer0 1701
ip nat inside source static tcp 192.168.0.253 1723 interface Dialer0 1723
