They both have their own separate WAN connection (we use a lot of bandwidth, hence the need for two WAN connections).

If anyone cares to comment on why it works perfectly this way, and not when using a NATed IP addresses, I'd be happy to read and learn. http://serverfault.com/questions/110009/vpn-returning-721-error-despite-successful-logins-to-from-other-locations But the reply goes through the same > channel as above, so the reply doesn't have this IP in the packet.

Microsoft also has a support article on Google if you use the search provided. Just to clarify. Similarly, I can successfully dial into the central site from my work PC. But > this issue is only for PPTP connections.

Can a Bridged network be the reason PPTP struggles when NATed to an assigned IP rather than when using the router's IP? Conclusion: I have NO clue as to why I have to use the router's public IP address rather than any of the other 31 public IP addresses our ISP assigned to If I use any of the other static public IPs, 208.38.4.102 - 208.38.4.116 in a NAT, it would take up to 6 retries for the connection to successfully connect.

When PPTP connections are made, the connection comes in and back out the same router (this I made sure).

FTP, WWW, RDP, PCAnywhere, SSL, PPTP, MAIL, etc...all these services are routed to internal servers/workstations.

Usually 721 just indicates that GRE is being blocked. When the server replies, the packet goes to the NAT router, is modified by NAT and gets the router's public IP as the sender's IP. A PPTP connection will definitely fail if GRE is > blocked at the router. Apple Info Site Map Hot News RSS Feeds Contact Us Copyright © Apple Inc.
