Connect to a server that is using fragment

[wlanrouter]

Hey there. Ist there any way or trick to connect to a OpenVPN Server that is using fragment? We have a lot of OpenVPN Server all over the world and I can't change Server config. On Windows Client it works perfect with this config:

Code: Select all

client
dev tun
proto udp

remote 210.210.210.210 5123

resolv-retry infinite
nobind
persist-key
persist-tun

comp-lzo
tun-mtu 1500
fragment 1300
mssfix


ca ca.crt
cert mysecret.crt
key mysecret.key


ns-cert-type server
verb 3

I can import it on Android if I erase the fragment line. But the connection will disconnect as soon as I try to send bigger packages. I tried a lot of changes like mssfix 1300, link-mtu 1200, tun-mtu 1300, 1280, 800. Nothing works. Any ideas?

Nobody? I though of reducing the outer fragment so the inner fragment will not come to it's limit.
