Error 721 Vpn Windows Xp
6 retries for any remote user to successfully created a remote PPTP connection 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 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 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,

You are the third person this past week who has had this issue... Hmmm... What router do you have? If it is a MS router, did you let it autoupdate itself? Also, have you applied any new security hotfixes lately?

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 connection error 721 1723, IP Protocol 47 (GRE) are opened.

Protocol (PPTP) client. You may even get an error 721 after making an unsuccessful attempt to establish a dial-up connection after upgrading your computer to Microsoft Windows XP from earlier versions. The exact error 721 description may vary from 'Remote PPP peer is not responding' to 'the remote computer is not responding'. Cause of Error 721 Point-to-Point Tunneling Protocol uses Generic Routing Encapsulation (GRE) for tunneled data and the error may occur if the network firewall does not permit the GRE protocol traffic. The Generic Routing Encapsulation protocol is used along with Point-to-Point Tunneling Protocol to create virtual private networks between the server and the client or between the clients. You may even encounter this error if the modem driver is not compatible with Windows XP. How to fix the Error 721 To resolve this error, you need to configure the network firewall so as to permit the GRE protocol 47. Also, you need to make sure that the firewall permits the TCP traffic on port 1723. Both of these conditions are required in order to establish the virtual private network connectivity by using Point-to-Point Tunneling protocol. Installing the latest Windows XP compatible driver for the modem can also fix the problem in some situations. Follow Us!
