I am unable to complete a connection to the aslv4. I have a single public IP on the WAN interface of a router running NAT. Behind the router I have 2 web servers and the outside interface of the asl. I had the port mapping done for 1723 both TCP and UDP to the outside interface of the asl. In the PPTP log I receive the following:
Oct 1 22:02:04 (none) pptpd[23020]: CTRL: Client 66.156.97.89 control connection started

Oct 1 22:02:35 (none) pppd[23021]: Connection terminated.
Oct 1 22:02:35 (none) pppd[23021]: Exit.
I am apparently reaching the proper port but can not authenticate. Any suggestions? I believe a port may be blocked that is necessary to complete the connection but I am unsure. Help is greatly appreciated. Thanks
