The new vpn service is awesome but it is frequently dropped

Post by C8288 » Sat Mar 09, 2013 3:55 am

The speed is good and it is very stable. But when I use vpn on ipad, the vpn network frequently disconnected...
I don't know the reason, maybe it is because of my ISP? I am from China and use vpn to access YouTube and Facebook. Please help me, thanks!
Btw, there is a small mistake in the top logo of this forum. It should be User's instead of Users'... :)
Thanks!

Hi C8288,

Any VPN servers in the list are unstable for L2TP from your ISP? Did you try others?

It is reported that some ISPs (e.g. China Unicom) are using NAT on their users to save the number of IP addresses.
Some NATs are too unstable to keep UDP session for long time. L2TP/IPsec uses UDP 500/4500, the session might be terminated suddenly.

By the way I think "Users'" is correct.

Thanks.
I am testing now.My ISP is China Unicom :(...
The VPN service is very stable on my pc but it is frequently dropped on my ipad. Perhaps it is because of the bugs of IOS?
