Good Evening, and thank you in advance for any help given.
Lan 1 - 192.168.0.0/24
Lan 2 - 192.168.100.0/24 (also has 192.168.101.0, 192.168.102.0, 192.168.103.0,192.168.104.0 and 192.168.108.0 all /24)
Lan 3 - 192.168.1.0/24
Lan 2 and 3 link to Lan 1 Via IPSEC
I have a 80Mb FTTC connection connected to a Cisco 887VA VDSL over POTS
I am generally happy with my internet speed which regularly peeks at approx. 25mb down and 17mb up although Im sure with some tweaks I could get more. However VPN performance is incredible poor.
Lan 2 has a 100mb Fibre connection and can get a internet speed of approx. 97mb
Lan 3 has a 20mb WiFi connection to some WISP and can generally get 20mb both directions
However Lan 2 using Wireshark seems to send a lot of retransmissions and out of sequence packets which cause issues
Lan 3 only ever really gets 500kb over the VPN.
Below is my sanitised configuration from the Cisco 887Va on Lan 1
Would anyone mind casting their eyes over it and tell me if I can improve the config or if im missing config which would help with speed issues/Retransmissions. Im sure there is a MTU/MSS issue somewhere between Lan 1 and Lan 2
Thank you for any help
Regards
Mark
