Error 721 Vpn Windows 2003
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 error 678 vpn the problem. The Problem: It can take up 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
Error 721 Directv
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 https://support.microsoft.com/en-us/kb/888201 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 http://www.pcreview.co.uk/threads/error-721-finally-resolved.1574450/ 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, 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 whet

Hello, I'm working on seting up a VPN connecting and having many problems. Ill try to include as much relivant information as possible: I've been working over the past week or so to setup a VPN between our Home Officer network and my step-sisters Home network so she can work there instead of runing back and forth. However, after many hours and even more headaches error 721 i still cant seem to get it working. I was configuring it connect to 2003 server but because i need to set it up on other XP Pro computers later i opted to try XP instead. The network(server side) consists of a Linksys BEFVP41 V2(vpn cable/dsl router) and a Wireless A+G router. Currently i have the vpn router setup as the gateway, the wireless is set in router mode. All ports(even on both routers) error 721 vpn VPN uses that i am aware of are forwarded to the server computer( PPTP/L2TP-IPSec pass-throughs) prot 47 and 48-50, ports 1723 and 500 are forwarded(for both TCP and UDP). I have ports forwarded on the client end as well(its useing a bellsouth dsl modem/router, i dont have specific information on it with me at my location) i beleive.(however i am unsure, are there any specific client side ports i need to open besides 1024-65524 range?) When i attempt to connect i receive error code 721 every time. I've checked everything and so far i dont beleive there is a firewall runing blocking ports anywhere. Norton is installed on all machines but no firewall is setup or enabled. Windows personal firewall are disabled on both ends as well as the router firewalls. I attempted to test DMZ hosting out to see if it was a problem with the routers but it wouldnt even connect to the IP at that point(i receive a different error at this point, saying it couldnt connect and the server may be unreachable). I can succesfuly ping every computer and both routers here on the office network as well asn ping the remote clients IP. The server connection has a static IP, the client is dynamic, our ISP(BellSouth) does not block VPN traffic either. I've looked over more
