 |
Running Firmware: DD-WRT v3.0-r33006
OpenVPN, Client Mode
I'm trying to optimize my OpenVPN tunnel MTU.
My default config for my DD-WRT is a MTU of 1452.
The openvpn tunnel default is 1500 (UDP Tunnel)
In the config screen, I'm trying to understand what the best settings for this situation are in relation to:
Tunnel UDP Fragment (value)
Tunnel UDP MSS-Fix (check or not)
In addtion/in lieu of settings in "Additional Config"
The OpenVPN docs and the wiki here are not clear to me.
My first assumption is with a 1452 MTU, anything with MSS would have to be AT MOST 1412 (1452-40), is that correct? |
