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?
