Hi!
I am currently trying out OpenVPN 2.0 beta 4 using server mode.
My config on the server looks like this:
dev tun
mode server
ifconfig 192.168.100.1 192.168.100.2
ifconfig-pool 192.168.100.4 192.168.100.254
push "route 192.168.100.1 255.255.255.255"
route 192.168.100.0 255.255.255.0
[...]
Everything works fine as expected. (Which is really great. I appreciate the
good work done here)
I am wondering why there is a subnet of size /30 assigned to the client. I
would expect a Point-to-Point device to receive only one ip adress and not
a /30 subnet.
tun0 Protokoll:Punkt-zu-Punkt Verbindung
inet Adresse:192.168.100.6 P-z-P:192.168.100.5
Maske:255.255.255.255
The netmask is also not which one would expect for a /30 network.
I have some servers running with lots of ppp devices. I am assigning also
adresses out of a pool. The two addresses do not lie within the same subnet.
ppp138 Link encap:Point-to-Point Protocol
inet addr:192.168.1.31 P-t-P:10.3.14.223 Mask:255.255.255.255
Is there any good reason for this /30 assignment?
Is there a config option to change this behaviour (I didn't find one)?
How many IPs can be assigned within a pool?
I found:
#define IFCONFIG_POOL_MAX 65536
in pool.h
Has anyone tested this beyond a class-C network?
Torge
