HH5 Infinity VPN issues


[link to this post]
 
Having some "interesting" issues trying to connect a laptop to the office via VPN and would appreciate any assistance.

If I connect via the home network, either wired or wifi, then without fail I get an error - host unreachable. Internet access is fine, it just wont connect to the VPN.

If, however, I connect via wifi to the BT WiFi with Fon network on the same HH5 then, once I've signed in to BT via a web browser, the VPN connects almost immediately.

Other than the network name and internal network IP range, no other settings have been changed on the HH5.

Hub version: BT Home Hub 5 (Type A) | Software version 4.7.5.1.83.8.204 | Last updated 22/01/15

Ideally, I'd want to connect via the home network (security) rather than the BT WiFi one (unsecured), but I can find no way to make it work.

What VPN protocol are you using?

Thanks smile

Just wish it worked for me as well! smile

It must come down to a router setting, as it works on the BT WiFi with Fon, just not on the specific network.

I'd rather not factory reset it, given that all that was changed was network name and internal IP range.

Have you tried turning the firewall off? have you tried putting the PC in the DMZ?
There's a setting on the Homehub for VPN, tried that?

The LAN IP range does not just happen to be the same as the LAN IP range at the VPN end?

When you can't get VPN working there seems to be no one to turn to for definitive help and advice. I've personally found that once you are absolutely sure that you are providing the right credentials and it still won't connect, reducing the MTU is often a golden bullet and in some cases replacing freebie routers from the ISP with a better quality router does the trick.

On the client PC, have you remembered to configure the connection for the pre shared key for authentication? Easy to forget about this step.

You don't have Parental Controls enabled, do you?

Parental controls not set. IP range differs from the work network, VPN setting for UDP port on the router set.

As I said, it works fine using BT WiFi with Fon, it just refuses to connect from the home network.

BT = [censored] Terrible (where VPNs are concerned!)
