"multihome" doesn't work, the OpenVPN server responds from its primary IPv4 address (the one the OS selects as the default source for routing towards the client), rather than the IPv4 address it was contacted on. So the initial two packets look like this: 01:07:47.896447 IP 84.209.244.191.38878 > 87.238.35.253.1194: UDP, length 14 01:07:47.897423 IP 87.238.35.145.1194 > 84.209.244.191.38878: UDP, length 26 The client (84.209.244.191) expects the response packet to come from the address it contacted as --remote (87.238.35.253), but instead the server responds from 87.238.35.145 which is its primary address. Doesn't work, after some retransmissions and reconnect attempts the client gives up. The server logs the following: Jan 11 01:07:47 greed ovpn-server[10222]: ::ffff:84.209.244.191 TLS: Initial packet from [AF_INET6]::ffff:84.209.244.191:38878 (via 2a02:c0:1001:100::253%eth0), sid=98e4314f 9ea08578 I find the "via 2a02:c0:1001:100::253%eth0" part interesting, as that's not even the primary IPv6 address of the interface.
