Hello,
I am configuring a RV160 as OpenVPN server. And I've got two problems:
After configuring the router I try to make a connection from "OpenVPN Connect" (as I have done to other OpenVPN servers).
I can't connect and I get the error "EVENT: option_error: sorry, 'fragment' directive is not supported, nor is connecting to a server that uses 'fragment' directive".
Apparently a setting should be changed on the router but I can't find anything similar via the web-interface.
Then I come to the second problem:
I would like to make a connection via the Console port, with Cisco blue cable and a RS232 port. Just as I have done earlier with other Cisco-routers. But no connection :-(
Any hint would be welcome!
Thank you in advance.

Thanks, but sorry for my ignorance: Where should this be done, on the client or the server? I haven't seen the parameter anywhere...

- Seems to be an openvpn (client parameter) :
Ref : https://openvpn.net/community-resources/reference-manual-for-openvpn-2-4/
>...
–fragment maxEnable internal datagram fragmentation so that no UDP datagrams are sent which are larger than max bytes.The max parameter is interpreted in the same way as the –link-mtu parameter, i.e. the UDP packet size after encapsulation overhead has been added in, but not including the UDP header itself.

Thanks for the reference, but:
I have configured TCP
I have tried with another client (tunXten), the connection works perfect
I have tried UDP with different max-parameters, same result.
I'm going to use the connection from an Android phone where I already have the OpenVPN-client installed.
So I'm a bit .....
