I am not able to authenticate to my MS PPTP server on the other side of a Watchguard x700 w/7.3 software.
I have configured a 1-1 NAT w/an available routable IP address mapped to an internal address of 10.0.0.96
I have configure a packet filter from ANY to the outside routable I used. I have also tried from any to the 10.0.0.96 address.
On the PPTP server I get a message about GRE not being passed but I am using the Watchguard PPTP filter that includes GRE. I see where you can't static NAT GRE so, that is not an option.
I am looking for help in troubleshooting this problem. Thanks....
