Hi! I am trying to connect the Tab to a PPtP VPN. No encryption as encryption has a lot of problems in Android. (I de-activated encryption in the checkbox at the Tab)
All my other phones work perfect (Droid and DroidX) with the same conf (no encryption), but the Tab seems to not being able to connect.
In the VPN server, I have the following message:
A connection between the VPN server and the VPN client x.x.x.x 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.
This happends in the tab, both in Wifi and 3G... so it's not verizon.
Any other devices connect perfect... any ideas where is the problem??
Tomorrow I am calling Samsung, as Verizon doesen't have an idea of what I am talking. Seems to me that there is something missing in the software of the Tab. Seems that the same problem happens with other samsung android Phones... Any ideas guys??
