The vpn tunnel only works well with small files (less than 20 kbytes) The same vpn client (key and config) from other locations works well. I tested the tunnel with tcp (instead of udp) connection, there was perfect.

08/01/2019 · Note: If the tunnel path-mtu-discovery command was not configured on the forwarding router in this scenario, and the DF bit was set in the packets forwarded through the GRE tunnel, Host 1 would still succeed in sending TCP/IPv4 packets to Host 2, but they would get fragmented in the middle at the 1400 MTU link. Also the GRE tunnel peer would have to reassemble them before it could decapsulate 26/11/2013 · Keep in mind that IPsec in tunnel mode adds an ESP header and an additional IP header for tunneling the packet (usually with an additional size of around 70-80 bytes). When a packet is nearly the size of the MTU and when you tack on this encapsulation overhead, it is likely to exceed the MTU of the outbound link. That’s where IP fragmentation kicks in – which could lead to performance Tunnel UDP MSS-Fix: Disabled; Additional Config section: Paste the below data; reneg-sec 0 persist-tun persist-key ping 5 ping-exit 30 nobind remote-random remote-cert-tls server route-metric 1 4.
