I'm just wondering if on my server I have this [code] push "dhcp-option DNS 208.67.222.222" [/code] and on my client config, I have [code] dhcp-option DNS 8.8.8.8 [/code] which dhcp-option would take effect? Also, which specific parameters am I only allowed to push to the client config?

push goes from server to client, not vice versa. The client cannot change [b]anything[/b] on the server.

pushed options tend to overrule client-side options; as for knowing which options can be pushed: you can push pretty much anything you want, but some options cannot be processed after the VPN link is up (e.g. change the ciphers, MTU sizes etc). All other options can be pushed from the server to the client.

What if a client has this option in his client config. Will he be able to change the dns on the server?

push "dhcp-option DNS 208.67.222.222"
