I'm struggling with setting up VPN connections reliably and was advised (by the VPN provider) to change my system's (17.1) MTU value to something between 900 and 1100. Although this strikes me as being on the low side, the default value apparently is 1500
Code: Select all
ifconfig | grep MTU
Although I'm not a networking expert, I do understand the basics ans so I've perused several postings regarding this topic, but the offered "solutions" have not been able to provide anything useful:
1. http://serverfault.com/questions/608931 ... amazon-vpc
I've changed the dhclient.conf file to include:
Code: Select all
interface "eth0" {
default interface-mtu 1492;
supersede interface-mtu 1492;
}
interface "lo" {
default interface-mtu 1492;
supersede interface-mtu 1492;
}
Code: Select all
sudo ethtool -K lo sg off
2. http://ubuntuforums.org/showthread.php?t=1284176
Tried the "interface-mtu" settings before as well as after the "request" entry: no success
3. http://www.ubuntugeek.com/how-to-change ... linux.html
Tried the interfaces file: added MTU 1100, but no success
Is anyone able to offer a solution or a poiting in the right direction? Help would be much appreciated. Many thanks in advance!
