Hi all,
I am having a bit of a struggle with a port forward off pptp & gre (the whole package offcourse) from the public nat outside interface towards the inside interface.
Here is a configuration example.
Here is an example of a normal portforward configuration. I want to ask your help in modifying this config with the goal of forwarding also GRE as a protocol.
int lo 10
ip address "public"
ip nat outside
int vlan 200
ip address 192.168.1.254 255.255.255.0
ip nat inside
ip access-list extended 100
permit ip 192.168.1.0 0.0.0.255 any
deny ip any any
To allow all hosts in the local subnet to access the internet
ip nat inside source list 100 interface lo 10 overload
Now, we know that the 192.168.1.1 is the pptp server.
ip nat inside source static 192.168.1.1 1723 interface lo 10 1723
Question his, what is the next step to allow GRE to pass from Wan to Lan toward the PPTP server ? (192.168.1.1).
Thank you for your help.
Kind Regards
Jan Meylaers
