I'm having really bad speeds using Poptop on my Centos 6 64 bit VPS. I get to 3mbps download but the connection is unstable. I think it is related to the MTU and MRU settings.
What I've done so far:
Added this to /etc/ppp/options.pptpd
Code:
nopcomp
noaccomp
mtu 1400
mru 1400
default-asyncmap
Changed this in /etc/pptpd.conf
Code:
localip EXTERNALIP
remoteip 10.0.0.100-199
(Note: there's also an OpenVPN service running on 10.8.0.0/24 & 10.8.1.0/24)
Added this to /etc/ppp/ip-up
Code:
/sbin/ifconfig $1 mtu 1400
ifconfig:

It says "dropped:1318" in "venet0". Maybe this is a problem?
How can I resolve the speed issues and get a stable connection? Thanks in advance!
