Error 721 Windows Vpn
Contents |
I have FINALLY resolved an ongoing issue with our VPN connections that we have been experiencing for over a year now. I will share these findings with this forum in case others can benefit from our situation. First let me explain the problem. The Problem: windows vpn error 800 It can take up 6 retries for any remote user to successfully created a remote PPTP connection windows vpn error 619 to our servers. Whenever we try to connect it display the following message: Verifying username and password... And it sit there displaying this message for about windows xp vpn error 721 30-40 seconds, then it says: "error: 721 The remote computer did not respond." Network Setup: We have two netopia routers on our network. They both have their own separate WAN connection (we use a lot of bandwidth, hence the need for two

WAN connections). One RAS server is configured to use one router as it's gateway, and the other RAS server uses the second router as it's gateway. When PPTP connections are made, the connection comes in and back out the same router (this I made sure). We use a multi-NAT for routing service request to internal servers. FTP, WWW, RDP, PCAnywhere, SSL, PPTP, MAIL, etc...all these services are routed to internal servers/workstations. We have approximately 32 public IP addresses, hence why we use Multi-NAT for routing public windows vpn port services to internal servers. Everything works perfectly, EXCEPT PPTP (VPN) connections. We have struggled with this for a year now. For whatever reason, it struggles to make a successful connection to our RAS servers. Like I said, it can take up to 6 retries to successfully connect to our RAS servers (up to 30 retries if the remote user is behind a Linksys router). The Fix: Today, I decided to try something different. I decided to use the router's public IP address for PPTP requests, instead of one of the other public IP addresses our ISP assigned us, and simply forward PPTP (TCP 1723 & IP 47) requests to the internal servers. Therefore, the only difference is that I am using a pingable IP address which happens to belong to the router instead of using one of the public IP addresses I have NATed. For whatever reason, this solved our problem with connecting to the RAS server. We no longer have to retry up to 6 times to successfully connect. 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 us. This was ONLY an issue with the PPTP service. All the other services work perfectly with the router's Multi-NAT table. In the end I don't know whether it's a router issue (ie, Netopia has problems routing PPTP requests), or a protocol issue (PPTP has problems when NATed), or whatever. All I ca

Resolution: If you have tried many thing error 721 other people suggest like rebooting, reloading hardware and re-installing the VPN or dial in connection, you still get the same problem. I will suggest to check the router settings and make sure TCP Port windows vpn error 1723, IP Protocol 47 (GRE) are opened. Also make sure that the router has the PPTP enabled and not firewall block the traffic. On the RAS server, check the DHCP settings.

and http://support.microsoft.com/kb/888201 shows possibly firewall config issue, maybe also the NAT type on the router she is using? probably be worth ensuring everything is upto date/latest firmware... 0 Jalapeno OP Jbenisek Feb 7, 2012 at 1:24 UTC Don't Panic Business Consulting is an IT service provider. Most routers have PPTP VPN Passthrough should be allow/on. Case 1: When a user attempts to access the Windows VPN server that is behind a Linksys WRT54G, he receives VPN Error 800 or 721. Troubleshooting: Upgrading the firmware fixes the problem. Note: you may need to re-set the router. Does she user Norton Internet Security? If so DO NOT Disable it UNINSTALL IT! Disable blocks all ports and makes the problem worse.      0 Tabasco OP MJB969 Feb 7, 2012 at 1:29 UTC Fixed it! Took her a new W7 laptop which I tested on Verizon Mobile Broadband, so I knew it worked. It got an error 800 at the users home. Got into the user's modem and found a setting to enable PPTP pass through.  0 Jalapeno OP Jbenisek Feb 7, 2012 at 1:51 UTC Don't Panic Business Consulting is an IT service provider. Great to hear. Did the verizon VPN work? 0 Tabasco OP MJB969 Feb 7, 2012 at 2:16 UTC The VPN worked fine on Verizon Mobile Hot Spot. Didn't work on the user's home Comcast until I enabled the PPTP passthrough. I have Comast at home as well, but my modem is about 6 years old. If I get a new one from them, I'll have to remember to enable that. 0 This discussion has been inactive for over a year.
