Vpn
Hi all!
First thread on this username, forgot what my old username was  and it won't accept any of my email addresses as being a member...oh well!Here goes... I have recently attempted to set up a VPN on my home server running Windows Server 2003 R2, all looks well, I can connect to the VPN locally and it authenticates me fine. However, on my router (Orange Livebox made by Inventel), I have forwarded TCP port 1723 to the server, but I receive error 721 when I attempt to connect via the internet. Is there a problem with my setup, or is my router incapable of allowin VPN? Any help would be greatly appreciated. jt999 |

Is VPN Passthrough enabled in your router configuration?
Your router may or may not support VPN Passthrough - I can not say for certain without knowing its make and model information. |

The router doesn't seem to have any options that mention VPN, all I know is that its an Inventel rebadged and sold as the Orange Livebox for orange broadband, if thats any help.
Thanks for your input jt999 |

GRE traffic (IP protocol 47)
Quote:
We had the same issue and later found that our pix 515e firewall was not properly configured for the GRE (IP protocol 47). Rectifying and correcting it solved our issue. Please read the technical documents for your router and see whether anything regarding gre is mentioned. Read somewhere that certain ISPs disable the GRE traffic for PPPoA/PPPoE (Usually home connections). If your ISP is not blocking the GRE traffic then it must be your router. Try to replace it with a cheap linksys BEFSR41 four port router (Which we used to confirm GRE was not blocked by our ISP), forward the tcp port 1723 to your VPN server and try to connect. VPN error 721 happens mostly or only when the GRE traffic is somehow restricted. Hope this helps you. regards
