[solved] Netgate 8200 + OpenVPN with and without DCO problem

[SwissSteph]

I have an OpenVPN configuration (without DCO) on my Android phone that works. If I activate the "DCO" checkbox in the configuration, the same phone becomes really slow in its connection (for setting it up and for surfing).

Do you have any idea why and what I could try to benefit from the advantages of DCO ... including the speed I don't have!

Thanks for your advice

My configuration dated from version 22.01 and then I went from version to version, now in 23.05 activating "DCO" and "QAT" on my 8200 crashed "UNBOUND".
I completely redid the "Wizard" and now I can activate "DCO" and "QAT" and everything works. I've taken all the "information" from my old setup, but well ... one more mystery!
