Description

site-to-site.

if set in openvpn client option "remote network" for example "192.168.18.0/24" -- openvpn client is crashed with parsing error.
For remobe this error need only(!) reboot server.

If need site-to-site routing - add command "route 192.168.18.0 255.255.255.0 192.168.220.9" (220.9 - is gateway ip in tunnel)

I cannot reproduce this. I tried a static key client and SSL/TLS client and everything worked as expected. The remote network was accepted, OpenVPN was running, route was in the table.

If you can narrow the symptoms down to a specific combination of options that may help, but as stated there isn't a bug I can identify.

crash does not always happen, in my network only 2 from 21 routers has this problem. PSK scheme.
BUT! problem with routes from "remote network" (in log: OpenVPN ROUTE: failed to parse/resolve route for host/network: 192.168.18.0) -- there is always 100%. Try it.
