I setup PPTP server (LOCATION A) at data center with 100x100 connection.
PPTP Client (LOCATION B) is connected to 100 x 10 connection.
EoIP tunnel is connecting the two locations through the PPTP tunnel, so I can assign devices at Location B IP addresses connected to Location A.
It all works ok, but the connection is really slow. When I speedtest.net a device at Location B using Location A’s IP addresses I am only getting a 10x2 at best.
Is this an MTU issue? I setup everything at 1500, including PPTP/EOIP.
Looking to get close to my full bandwidth at Location B and utilize the public IPs from location A.
What encryption settings are you using, and what hardware are the routers?
In general for encrypted tunnels, you should use ppc, tile, or x86 architecture routers. The ppc and tile architectures support hardware acceleration for encryption. Most x86 routers have “computer grade” CPUs that are able to handle the encryption much better than the mipsbe processors. If either end of the tunnel is a mipsbe processor (RB2011, CRS series, RB951, etc), then I would expect a max of 5-10Mbps of traffic across the tunnel – and you should see very high CPU usage on the mipsbe unit when passing that much traffic.
We have tried switching from a pptp/eoip to a ipsec/eoip and still the same results, around 30%-35% of our total bandwidth. We just can not get the eoip tunnel to push more then 35mbps. It seems with setting the eoip mtu to 1390 gives us the best results but still not where we need it to be.
The hardware at location A is a CCR1009-8G-1S-1S+ in to a 100/100 link in a data center and location B is a CCR1009-8G-1S-1S+ with a 300/20 link at our office.
I have a link with two RB921’s and the max I get over an EoIP tunnel is 25 - 35 Mbit. If I change the setup so that there is no EoIP tunnel and the device that I have on the remote side, a NAS, is part of the same network, I get 75-90 Mbit.
*note: The rb921 has gigabit ports, but I have them linked at 100 mbit, one side has a RB493AH connected and the other has a RB2011UAS ( POE injector that is used will only allow 100 Mbit link)
And In fairness, the Iomega NAS usually only gets these 75-90 Mbit when connected locally anyways.
So, why the HUGE difference in data rates when using an EoIP? Don’t know. CPU rates on all of the MT hardware is low ( Don’t know exact values)
The wireless link rates can get up to 200+ Mbit easily.
