Hi

Ref: https://forums.openvpn.net/viewtopic.php?f=6&t=24318
(Not interested in a solution for it, just for info)

Details of *my* question:

Server.conf:

push "redirect-gateway def1 block-local"
push "dhcp-option DNS 10.100.0.X"
push "block-outside-dns"

Note:
1. There is no push "route 10.100.0.X"
2. redirect-gateway should force 10.100.0.X over the tunnel
(presuming there is no specific route on the client)
3. (eg) Server LAN 192.168.101.0/24
Client LAN 192.168.121.0/24

In this scenario:
Would block-outside-dns block access to the pushed DNS server ?

thanks

Never mind .. of course it would not block dns otherwise private VPNs
could not use google dns etc.
