can I VPN?
 

Hi
I have a Asus WL-520g wireless router connected to my NTL cable modem.
The cable moden is a NTL-Home 100,
I tried a VPN connection last week in the USA and everything worked fine.
When I try to connect to the VPN from my home I get a connection error

A connection between the VPN server and the VPN client has been established, but the VPN connection cannot be completed. The most common cause for this is that a firewall or router between the VPN server and the VPN client is not configured to allow Generic Routing Encapsulation (GRE) packets (protocol 47). Verify that the firewalls and routers between your VPN server and the Internet allow GRE packets. Make sure the firewalls and routers on the user's network are also configured to allow GRE packets. If the problem persists, have the user contact the Internet service provider (ISP) to determine whether the ISP might be blocking GRE packets.

My question is does my router and/or NTL allow GRE

Thanks

I use my NTL connection to make VPN connections from home to work, so yes you can through NTL.

Your router supports VPN passthrough. Is it switched on?

Thanks for your reply Wicked and Crazy,
I could not see anything in the router setting for VPN passthrough. Could it be named as something else?

Thanks

Can you VPN without the router in place (plug the PC into the CM), then you will know it is a router problem.

I tried that last night with a network cable and still the same. Do you know if a NTL cable modem have a firewall setting?
Thanks

You did power off the modem and power back on again when swapping over from router to direct connection?

VPN is not barred on ntl networks, in fact I use it regularly. I'd suggest it's a local error on your PC, or at the server you are connecting to.

IPSEC Passthrough
PPTP Passthrough
L2TP Passthrough

Thanks for all your help Wicked and Crazy, I got a new error today
Error:
732
PPP parameter negotiation did not succeed because the local and remote computers did not agree on a common set of parameters. Contact your system administrator to verify the configuration of network protocols such as TCP/IP or IPX. Also, your system administrator can enable PPP logging by using the Netsh.exe utility, which may help identify the PPP negotiation problem.

Any idea what could causes that error

Thanks

Re: can I VPN?
 

Did you do what Rob said? Remove the router and then power cycle the CM once it is plugged directly into the computer.
Then VPN.
Can you then surf the net?
Can you then VPN? If you cannot, the problem is with the client or the host, not the network.

Sorry.. wrong thread.

Re: can I VPN?
 

Yip, did all that.
Can surf the net, but still can't VPN
I'm getting the host setting checked
Thanks
