Hi, <skip>
and the guide continues with "allows IPv4 packets to be transmitted over > a link with MTU 1473 or higher" > > Is this a typo? A while ago I have tested this part and turns out that mssfix value indeed *includes* UDP and IP headers, contrary to what documentation says: > UDP packet size after encapsulation overhead has been added in, but not including the UDP header itself I just gave it another try and observed the same behavior - outgoing IP packet size equals mssfix value. I have a setup where the OpenVPN server is behind a link with MTU 1350. > The VPN uses UDP. > What can be the maximal mssfix size then, 1322 bytes? > Based on observation above, mssfix 1350 should be a safe option. -- -Lev
