I have a remote site in the UK that is getting slow speeds through our L2L IPSEC VPN. We have a 50 mb/50mb connection here (in NY) and they have a 10mb/8mb connection on their end.

However with testing, the highest connection speeds that I am seeing are about 1.5 mb/s. Are there any settings that I can change to speed things up?

Currently my interfaces have a 1500 MTU. Is there are way to lower VPN traffic to a MSS of 1420, so large packets wont be split into two packets?

Hi,

It seems there is delay problem, how many is the average ping time between two ASA endpoints?

Best regards,
