Hi, I've setup a server with Topology Subnet, and push static IP to clients. server config: [code] topology subnet push "topology subnet" ifconfig 10.10.0.1 255.255.0.0 # server IP address client-config-dir ccd [/code] ccd client file: [code]ifconfig-push 10.10.111.2 255.255.0.0[/code] When I do a ifconfig on the client I see: [code]inet addr:10.10.111.2 P-t-P:10.10.111.2 Mask:255.255.0.0[/code] What is the P-t-P?? why is it the same as the client IP? Thank you

on another client that is running another distro if I do ifconfig I get : [code]inet 10.10.111.3 netmask 255.255.0.0 destination 10.10.111.3[/code] The wording are different, but I think they mean the same thing. (p-t-p and destination) what exactly are theycould someone explain? or is my config wrong? thank you.

Topology Subnet shows P-t-P

Hi, I've setup a server with Topology Subnet, and push static IP to clients.

server config:

topology subnet
push "topology subnet"
ifconfig 10.10.0.1 255.255.0.0 # server IP address
client-config-dir ccd

ccd client file:

ifconfig-push 10.10.111.2 255.255.0.0

When I do a ifconfig on the client I see:

inet addr:10.10.111.2  P-t-P:10.10.111.2  Mask:255.255.0.0

What is the P-t-P?? why is it the same as the client IP?

Thank you

It is normal even with --topology subnet

eg:

tun108: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST>  mtu 1500
        inet 10.8.0.2  netmask 255.255.255.0  destination 10.8.0.2

All tunnel nodes are always p-2-p .. --topology is something unique to openvpn

Under the hood, openvpn always routes to the other end of the tunnel
with the exception on the server in P2MP mode. ie. with multiple clients,
in that case the openvpn process maintains an internal routing table.

ok, thank you.
I just want to ensure it is normal and not a result of foul configuration.
