OpenVPN peers prior to 2.4, or peers with data cipher negotiation disabled, will not be able to connect to a 2.5 peer unless option data_fallback_ciphers is set on the 2.5 peer and it contains a cipher supported by the client.

For users who need compression, we build with LZ4 support by default. LZO in OpenVPN pulls in liblzo at approx. 32 kB. OpenWrt users will no longer be able to connect to OpenVPN peers that require LZO compression, unless they build the OpenVPN package themselves.
