Looking around the interweb's it seems that one area that this firmware as made a slight improvement on is VPN.
Quoting from
http://forum.synology.com/enu/viewtopic.php?f=145&t=...
I have recently upgraded to BT Infinity Fibre broadband, and my router has changed from BT Homehub 4 to BT Homehub 5.
Before this change, I was able to successfully VPN into my Synology 413J.
I have configured the BT Homehub 5 port forwading exactlty the same as it was with BT Homehub 4.
I can successfully remotely connect to 413J via DNS address, but unable to VPN into it.
Receive message "Verifying user name and password", which appears to succeed, then,
after some time, receive message "Error 800: The remote connection was not made because the attempted VPN tunnels failed ....."
Anybody have any ideas how to resolve this ???
The after this current firmware update;
I progressed the issue with BT and they provided an Openreach modem which I installed with the BT Homehub 4. However this did not resolve the VPN issue.
BT support performed VPN testing on Synology, and confirmed that VPN was OK on ADSL line with HH4, but not OK on Fibre with Openreach Modem/HH4 or HH5.
BT hub developers worked on the issue and updated the HH5 firmware.
VPN now OK using PPTP and L2TP-Certificate authentication protocols.
Still unable to establish VPN connection using L2TP - pre-shared key
BT are aware of this and currently working on the issue.
My original HH5 firmware was 4.7.5.1.83.8.173.1.6, Current firmware 4.7.5.1.83.8.204
BT inform me that they are currently rolling out the firmware update to existing HH5 customers
I don't use VPN on the HH5. But I thought it was interesting information. Not sure if others have similar issues before, and then fixed after?
Demon => Freeserve => Pipex => Be => Sky => BT Infinity 2
