Hi,
had the same problem with a pptp vpn (don't ask why we use pptp). As
described i had to set the MTU of the physical network adapter (e.g.
eth0) to 1000 to get the VPN working without disconnectes all the time.
You can set the MTU easily via the network manager on the "ethernet"
tab, but you
Hi All,
I have a good news to share, I could solve this problem after around a week.
There are couple of points.
# I have this problem, only with my Home Wifi. It was working fine with office
Wifi / Smartphone Hotspot.
# I could solve the problem by simply changing MTU value. Refer below
I've had the same problem for about a year, and now, I think, I've
finally found the way to fix it (at least somehow).
Looks like in my case it was the same as in

manager/+bug/991666/comments/16 (duplicate routes entries).
So what I've done.

I have exactly the same problem on Ubuntu 16.04. I have created a vpn
connection and it disconnects after almost 5 minutes. One weird thing is
that the laptop fan starts working with a high speed and exactly at the
same moment the vpn disconnects.

Hi all,
I've experienced a very simmilar issue on 14.04 as well. The reason of
my case actually was in routing table, in particular - routes pushed by
VPN server. Those routes were wrong or interpreted incorrectly and some
kind of packet collision was happening shortly after connecting VPN.

Hi everybody,
I have the exact same symptoms on 14.04 with a PPTP VPN.
I have a very strong feeling this is related to custom routes. I can initiate
the VPN and have it working (had it up for at least 15min without problems),
but as soon as I add a custom route on the command line the
Weird. It has stopped disconnecting once I moved custom routes from VPN
connection to Wi-Fi connection settings.

For me the issue occurs with Juniper SSL VPN. Apparently network manager
adds the original default route, I'd guess upon DHCP renew, which
overrides the default route that should go to my VPN tunnel (from
/var/log/syslog):
NetworkManager[xxx]: info Policy set 'xxx' (wlan0) as default for IPv4

I've been using the Wifi connect now for 16 hours:
Bus 001 Device 002: ID 148f:3072 Ralink Technology, Corp. RT3072
Wireless Adapter
The PPTP VPN connection has stayed up for the entire time - not one
single disconnect. The only problem is the RT3072 is incredibly slow
compared to my wired
I believe I have found what was casuing the problem in my case. I have a
Realtek R8168 onboard ethernet, but Ubuntu was loading the Realtek R8169
driver.
lspci | grep -i eth output:
01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL8111/8168B PCI Express Gigabit Ethernet controller
Sorry, looks like I spoke too soon (post #4). The disconnections are
still occuring even though I have replaced the R8169 with the R8168
module. I'm now testing with a WiFi dongle, will see how solid/stable my
PPTP connection is using different networking equipment.
