Adjusting MTU speeds up a problematic VPN connection

Question:

I can connect to the VPN server using Checkpoint SecureRemote but the network is very very slow. A sniffer tool shows many bad packets. Any ideas?

Answer:

I would like to explore one detail with you. Please go to \Program Files\CheckPoint\SecuRemote\bin and find MtuAdjust.exe. Double-click it, choose Yes to continue, choose "Adjust MTU for all adapters", edit 1500 to be 1400, leave "Enable Path MTU Discovery" checked and press OK. This will assure that the MTU for NIC is set to 1400. This will prevent packet fragmentation which could slow or prevent encrypted traffic.

MTU means 'Maximum Transmittable Unit' and specifies the maximum size datagram IP that may pass to a driver. On an Ethernet network, MaxMTU will default to 1500.

Note: This tool window will always come up with a default value of 1500; this does not indicate the actual MTU setting of the NIC. After you set the MTU to 1400, let me know any noticeable changes.

Note 2: If you use a different VPN client software you can still adjust the MTU. E.g. you can find the value directly in your Windows registry here:

HKEY_LOCAL_MACHINE\SYSTEM\CurentControlSet\Services\NdisWan\Parameters\Protocols\0

Change the dword ProtocolMTU to whatever MTU you want to run.

You can also download a tool that does this job for you: MTU-Speed Pro.

this is not windows related. The thing with the MTU always makes to connection to have a slower d/l rate - not a VPN specific . Anyway this help in trying to set up a VPN and PPPoE connection.

blind then!!! Time went, we have lived with him a floor of year as usual Young married couple. But then he
became any to another, as though him Have changed. He began to shout at me, and soon at all did not turn on
me Due attention. But after even three months all was found out. There is I at him there was not one. I has
found out, that at him was much Mistresses whom he started to meet even more often. Sometimes he at all Came
home, explaining it is the work. In one day I was released from work before, and have come home much earlier
than usually. I had a key, and I have opened a door. When I have entered into a room could not believe to
it. He sat from one of The mistresses. On a table there was a bottle of champagne and they had fun. On my
question 'Who it with you?', he has told 'the Girlfriend on work'. Then he has approached to me and has
asked to leave me. Such impudence I from Him did not expect! During that moment I would not like to live. I
did not know, that with By itself to do. Late at night, I went along the street with bitter tears on the
person, Also did not wish to live. Then I have gone to my girlfriend. And further at me were Strong
emotions. I roared, and laid on a bed. In a month we with him Have divorced. After we have divorced, I saw
