MTU inconsistent local and remote
-
Hi,
I always have this Warning when I connect iphone or android to OpenVPN server :
WARNING: 'link-mtu' is used inconsistently, local='link-mtu 1569', remote='link-mtu 1553'
I tested to find my max MTU from the internet connexion the OpenVPN client with different ping test to found the max MTU is 1472
ping -n 1 -l 1472 -f 8.8.8.8I tried to adjust the MTU (always on both side server and client) by adding both this options : "tun-mtu 1472". The MTU change when I'm connecting but again, the MTU isn't the same on both side and its not 1472 :
WARNING: 'link-mtu' is used inconsistently, local='link-mtu 1523', remote='link-mtu 1527'I had some authenticate/decrypt packet error, I switched to TCP and that seems to resolved my problem, but this warning continue to appear in logs.
I've done some research on the internet, a lot people talk about change parameter (tun-mtu, link-mtu) some people said that's not a problem (false alarm) but I dont think, I think VPN is really inconsistent and I got some disconnect because that.
Thanks for any suggestions.
